The following information is for FCC compliance of Class A devices: This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio-frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications. Operation of this equipment in a residential area is likely to cause harmful interference, in which case users will be required to correct the interference at their own expense. The following information is for FCC compliance of Class B devices: The equipment described in this manual generates and may radiate radio-frequency energy. If it is not installed in accordance with Cisco’s installation instructions, it may cause interference with radio and television reception. This equipment has been tested and found to comply with the limits for a Class B digital device in accordance with the specifications in part 15 of the FCC rules. These specifications are designed to provide reasonable protection against such interference in a residential installation. However, there is no guarantee that interference will not occur in a particular installation. You can determine whether your equipment is causing interference by turning it off. If the interference stops, it was probably caused by the Cisco equipment or one of its peripheral devices. If the equipment causes interference to radio or television reception, try to correct the interference by using one or more of the following measures: • Turn the television or radio antenna until the interference stops. • Move the equipment to one side or the other of the television or radio. • Move the equipment farther away from the television or radio. • Plug the equipment into an outlet that is on a different circuit from the television or radio. (That is, make certain the equipment and the television or radio are on circuits controlled by different circuit breakers or fuses.)

CHAPTER
1
Product Overview This chapter provides physical and functional overviews of the Cisco 12012 Gigabit Switch Router (GSR). It contains physical descriptions of the router hardware and major components, and functional descriptions of the hardware-related features. The Cisco 12012 is a member of the Cisco 12000 series of gigabit switch routers. The Cisco 12012 is aimed at scaling the Internet and enterprise backbones to speeds of OC-3/STM-1 (155 Mbps), OC-12/STM-4 (622 Mbps), and OC-48/STM-16 (2.4 Gbps). The Cisco 12012 is built around a high-speed switching fabric that is scalable from 5 to 60 Gbps, providing high-performance to support IP-based local and wide-area networks (WANs). The Cisco 12012 has two separate card cages; the upper card cage and the lower card cage. The upper card cage has 12 user-configurable slots that support a combination of line cards and a Route Processor (RP). The rightmost slot in the upper card cage supports a non-configurable alarm card. Network interfaces reside on line cards that provide connection between the router’s switch fabric and the external networks. The lower card cage has five slots for the cards containing the switch fabric: clock and scheduler cards (CSCs) and switch fabric cards (SFCs). The lower card cage is keyed; the top two slots accept clock and scheduler cards, and the lower three slots accept switch fabric cards. You can configure the Cisco 12012 for either source AC operation or source DC operation. AC-input or DC-input power supplies reside in a power supply bay located near the bottom of the frame.
Note The Cisco 12012 does not support a mixture of AC- and DC-input power supplies.
Product Overview 1-1
Physical and Functional Overviews
Warning AC operation requires a minimum configuration of two AC-input power
supplies.
Two blower modules, one mounted at the top of the frame and one mounted at the bottom of the frame, provide cooling air to the system.
Physical and Functional Overviews The Cisco 12012 is a modular system consisting of the following components (see Figure 1-1):
•
Frame—a rigid metal structure that is 19-inches (48.3-cm) wide, 21-inches (53.3-cm) deep, and 56-inches (142.2-cm) high and weighs 75 lb (34 kg) empty. Three sets of rails in the frame support the other three major components: a card cage assembly and two blower modules. The frame mounts into either a telco-style or four-post rack that is secured to the building structure.
•
Card cage assembly—a sheet metal enclosure that mounts in the frame. The card cage assembly consists of the upper card cage, the lower card cage, and the power supply bay. All three components are tied together electrically through a passive system backplane in the back of the card cage assembly. The upper card cage has 12 vertical slots for line cards and an RP. A unique slot (rightmost slot) in the upper card cage supports an alarm card. The lower card cage has five horizontal slots for the switch fabric. A removable air filter in a hinged air filter tray is mounted in front of the lower card cage. The power supply bay is at the bottom of the card cage assembly; it has slots for up to four AC-input power supplies or up to two DC-input power supplies.
•
Blower modules—two identical blower modules that slide on rails into the top and bottom of the frame. They provide cooling air for all of the components in the card cage.

Physical and Functional Overviews
The front of the Cisco 12012 provides access to all system components, making the system easy to service. All its major components are field-replaceable units (FRUs), including the following:
• • • • • • •
Gigabit Route Processor (GRP) or Performance Route Processor (PRP) Line cards Clock and scheduler cards Switch fabric cards Alarm card Power supplies Blower modules
The following sections provide brief overviews of each FRU. Chapter 7, “Maintaining the Cisco 12012,” and separate documents called configuration notes contain instructions for removing and replacing FRUs. For information on ordering FRUs, contact a customer service representative.
Gigabit Route Processor Each Cisco 12012 GSR has one main system (or route) processor. The route processor (RP) processes the network routing protocols and distributes updates to the Cisco Express Forwarding (CEF) tables on the line cards. The RP also performs general maintenance functions, such as diagnostics, console support, and line card monitoring. Two types of RPs are available for the Cisco 12012 GSR:
• •
Gigabit Route Processor (GRP) Performance Route Processor (PRP)
When not explicitly specified, this document uses the term route processor (RP) to indicate either the GRP or the PRP.
Note If you install a second, redundant RP, it must be of the same type as the primary RP.

Building and distributing routing tables to line cards Providing general system maintenance functions
Product Overview 1-5
Physical and Functional Overviews
The GRP communicates with the line cards either through the switch fabric or through a maintenance bus (MBus). The switch fabric connection is the main data path for routing table distribution as well as for packets that are sent between the line cards and the GRP. The MBus connection allows the GRP to download a system bootstrap image, collect or load diagnostic information, and perform general, internal system maintenance operations. The GRP plugs into any slot in the upper card cage in the Cisco 12012 except the rightmost slot, which is reserved for the alarm card. The GRP contains the following components:
•
IDT R5000 Reduced Instruction Set Computing (RISC) processor used for the CPU. The CPU runs at an external bus clock speed of 100 MHz and an internal clock speed of 200 MHz.
•
Up to 256 megabytes (MB) of parity-protected, extended data output (EDO) dynamic random-access memory (DRAM) on two, 60-nanosecond (ns), dual in-line memory modules (DIMMs); 64 MB of DRAM is the minimum shipping configuration.
•
512 kilobytes (KB) of static random-access memory (SRAM) for secondary CPU cache memory functions (SRAM is not user configurable or field upgradeable).
• •
512 KB of NVRAM (NVRAM is not user configurable or field upgradeable).
•
Air-temperature sensors for environmental monitoring.
Most of the additional memory components used by the system, including onboard Flash memory (8-MB) and up to two PCMCIA-based Flash memory cards. The default GRP PCMCIA Flash memory is 20 megabytes (MB).
The Cisco IOS software images that run the Cisco 12012 reside in Flash memory, which is located on the GRP in the form of a single in-line memory module (SIMM), and on up to two Personal Computer Memory Card International Association (PCMCIA) cards (called Flash memory cards) that insert in the two PCMCIA slots (slot 0 and slot 1) on the front of the GRP. (See Figure 1-2.) Storing the Cisco IOS images in Flash memory enables you to download and boot from upgraded Cisco IOS images remotely or from software images resident in GRP Flash memory. The Cisco 12012 supports downloadable system software for most Cisco IOS software upgrades, which enables you to remotely download, store, and boot from a new Cisco IOS image.

Caution
SRAM SRAM provides secondary CPU cache memory. The standard GRP configuration is 512 KB. Its principle function is to act as a staging area for routing tables update information to and from the line cards. SRAM is not user configurable or field-upgradeable.
Product Overview 1-9
Physical and Functional Overviews
NVRAM The system configuration, software configuration register settings, and environmental monitoring logs are contained in the 512-KB NVRAM, which is backed up with built-in lithium batteries that retain the contents for a minimum of five years. NVRAM is not user configurable or field-upgradeable.
Before you replace the GRP in the system, back up the running configuration to a Trivial File Transfer Protocol (TFTP) file server or an installed Flash memory card so you can retrieve it later. If the configuration is not saved, the entire configuration will be lost—inside the NVRAM on the removed GRP—and you will have to reenter the entire configuration manually. This procedure is not necessary if you are temporarily removing a GRP; lithium batteries retain the configuration in memory until you replace the GRP in the system.
Caution
Flash Memory Both the onboard and PCMCIA card-based Flash memory allow you to remotely load and store multiple Cisco IOS software and microcode images. You can download a new image over the network or from a local server and then add the new image to Flash memory or replace the existing files. You can then boot the routers either manually or automatically from any of the stored images. Flash memory also functions as a TFTP server to allow other servers to boot remotely from stored images or to copy them into their own Flash memory.
System Status LEDs This section describes the two types of system status LEDs used on the GRP: LED indicators and alphanumeric LED displays.
•
The GRP has the following eight LED indicators: — Two PCMCIA activity LEDs (one per PCMCIA slot): these LEDs light when the slot is accessed. The LEDs receive power from the switched slot voltage. — Four RJ-45 Ethernet port LEDs: these LEDs are used in conjunction with the RJ-45 Ethernet connector. When the MII Ethernet port is in use, the LEDs are disabled. The LEDs indicate link activity, collision detection, data transmission, and data reception.
1-10 Cisco 12012 Gigabit Switch Router Installation and Configuration Guide
Physical and Functional Overviews
— Two RJ-45 or MII Ethernet port select LEDs: these LEDs, when on, identify which one of the two Ethernet connections you selected. When the RJ-45 port is selected, its LED is on and the MII LED is off. When the MII port is selected, its LED is on and the RJ-45 LED is off.
•
The alphanumeric displays are organized as two rows of four characters each. The displays’ content is controlled by the MBus module software. The displays’ content is controlled by the GRP’s MBus module software. Both rows of the display are powered by the MBus module. These alphanumeric displays provide information about the following: — System status messages that are displayed during the boot process — System status messages that are displayed after the boot process is complete During the boot process, the alphanumeric LED displays are controlled directly by the MBus. After the boot process, they are controlled by the Cisco IOS software (via the MBus), and display messages designated by the Cisco IOS software. The following levels of system operation are displayed: — Status of the GRP — System error messages — User-defined status/error messages
Note A complete, descriptive list of all system and error messages is located in the Cisco
IOS System Error Messages publications.
Soft Reset Switch A soft reset switch provides a reset to the R5000's software on the GRP. Access to the soft reset switch is through a small opening in the GRP faceplate. To depress the switch, you must insert a paperclip or similar sharp pointed object into the opening.
To prevent system problems or loss of data, use the soft reset switch only at the advice of Cisco service personnel.
Caution
Product Overview 1-11
Physical and Functional Overviews
PCMCIA Slots The GRP has two PCMCIA slots available. Either slot can support a Flash memory card or an input/output (I/O) device as long as the device requires only +5 VDC. The GRP supports Type 1 and Type 2 devices; it does not support +3.3 VDC PCMCIA devices. Each PCMCIA slot has an ejector button for ejecting a PCMCIA card from the slot.
Asynchronous Serial Ports Two asynchronous serial ports on the GRP, the console and auxiliary ports, allow you to connect external devices to monitor and manage the system. The console port is an Electronics Industries Association/Telecommunications Industry Association (EIA/TIA)-232 receptacle (female) that provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal.
Note EIA/TIA-232 was known as recommended standard RS-232 before its acceptance
as a standard by the Electronic Industries Association (EIA) and Telecommunications Industry Association (TIA).
The auxiliary port is an EIA/TIA-232 plug (male) that provides a data terminal equipment (DTE) interface; the auxiliary port supports flow control and is often used to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management.
Ethernet Port The GRP has one Ethernet port available, using one of the following two connection types:
•
RJ-45 receptacle: an 8-pin media dependent interface (MDI) RJ-45 receptacle for either IEEE 802.3 10BaseT (10 Mbps) or IEEE 802.3u 100BaseTX (100 Mbps) Ethernet connections.
•
MII receptacle: a 40-pin media independent interface (MII) receptacle that provides additional flexibility in Ethernet connections. The pinout of this standard 40-pin receptacle is defined by the IEEE 802.3u standard.

Physical and Functional Overviews
Note The RJ-45 and MII receptacles on the GRP represent two physical connection
options for one Ethernet interface; therefore, you can use either the MDI RJ-45 connection or the MII connection, but not both simultaneously.
Performance Route Processor Each Cisco 12012 GSR has one main system (or route) processor. The route processor (RP) processes the network routing protocols and distributes updates to the Cisco Express Forwarding (CEF) tables on the line cards. The RP also performs general maintenance functions, such as diagnostics, console support, and line card monitoring. Two types of RPs are available for the Cisco 12012 GSR:

Flash memory contains the Cisco IOS boot image (bootflash) and is not field replaceable. 2 Flash disk— The PRP ships with a Flash disk that can be installed in either Flash disk
slot. (See Figure 1-5.) The Flash disk contains the Cisco IOS software image. Storing the Cisco IOS images in Flash memory enables you to download and boot from upgraded Cisco IOS software images remotely, or from software images that reside in PRP Flash memory. Cisco 12000 series Internet Routers support downloadable system software for most Cisco IOS software upgrades. This enables you to remotely download, store, and boot from a new Cisco IOS software image. The Cisco IOS software runs from within the PRPs SDRAM. Figure 1-5 shows the locations of the various hardware components on the PRP.

Caution Cisco Systems strongly recommends that you use only Cisco-approved memory.
To prevent memory problems, SDRAM DIMMs must be +3.3VDC, PC133-compliant devices. Do not attempt to install other devices in the DIMM sockets.
SRAM SRAM provides 2 MB of parity-protected, secondary CPU cache memory. Its principal function is to act as a staging area for routing table updates and for information sent to and received from line cards. SRAM is not user configurable and cannot be upgraded in the field.
NVRAM NVRAM provides 2 MB of memory for system configuration files, software configuration register settings, and environmental monitoring logs. This information is backed up with built-in lithium batteries that retain the contents for a minimum of 5 years. NVRAM is not user configurable and cannot be upgraded in the field.
Flash Memory Flash memory allows you to remotely load and store multiple Cisco IOS software and microcode images. You can download a new image over the network or from a local server and then add the new image to Flash memory or replace the existing files. You then can boot the routers either manually or automatically from any of the stored images. Flash memory also functions as a Trivial File Transfer Protocol (TFTP) server to allow other servers to boot remotely from stored images or to copy them into their own Flash memory. The onboard Flash memory (called bootflash) contains the Cisco IOS boot image, and the Flash disk contains the Cisco IOS software image. A 64-MB ATA Flash disk ships by default with the PRP. Table 1-4 lists the supported Flash disk sizes and their Cisco product numbers.

System Status LEDs The sections describes the two types of system status LEDs used on the PRP: LED indicators and alphanumeric LED displays. The device or port activity indicators consist of the following functional groups:
•
Two Flash disk activity LEDs (labeled SLOT-0 and SLOT-1)—1 LED per Flash disk slot: these go on when the slot is accessed.
•
Four RJ-45 Ethernet port LEDs (labeled LINK, EN, TX, and RX): used in conjunction with each of the RJ-45 Ethernet connectors. Each connector includes a set of 4 LEDs that indicate link activity (LINK), port enabled (EN), data transmission (TX), and data reception (RX).
•
Two Ethernet connection LEDs (labeled PRIMARY): these two LEDs, when on, identify which of the two Ethernet connections is selected. Since both ports are supported on the PRP, the LED on port ETH0 is always on. The ETH1 LED goes on when it is selected.
The alphanumeric display LEDs are organized as two rows of four characters each and are located at one end of the card. These LEDs provide system status and error messages that are displayed during and after the boot process. The boot process and the content displayed are controlled by the PRPs MBus module software. At the end of the boot process, the LEDs are controlled by the Cisco IOS software (via the MBus), and the content displayed is designated by the Cisco IOS software. The alphanumeric display LEDs provide information about the following:
• •
Status of the PRP System error messages

Physical and Functional Overviews
•
User-defined status and error messages
Note A complete, descriptive list of all system and error messages is located in the Cisco
IOS System Error Messages publications.
Soft Reset Switch The soft reset switch causes a nonmaskable interrupt (NMI) and places the PRP in ROM monitor mode. When the PRP enters ROM monitor mode, its behavior depends on the setting of the PRP software configuration register. For example, when the boot field of the software configuration register is set to 0x0, and you press the NMI switch, the PRP remains at the ROM monitor prompt (rommon>) and waits for a user command to boot the system manually. But if the boot field is set to 0x1, the system automatically boots the first IOS image found in the onboard Flash memory SIMM on the PRP.
Caution The soft reset (NMI) switch is not a mechanism for resetting the PRP and
reloading the IOS image. It is intended for software development use. To prevent system problems or loss of data, use the soft reset switch only on the advice of Cisco service personnel.
Access to the soft reset switch is through a small opening in the PRP faceplate. To press the switch, you must insert a paper clip or similar small pointed object into the opening.
Flash Disk Slots The PRP includes two Flash disk (PCMCIA) slots. Either slot can support an ATA Flash disk or a Type 1 or Type 2 linear Flash memory card. The PRP ships by default with one 64-MB ATA Flash disk.
Note The PRP only supports +5VDC Flash disk devices. It does not support +3.3VDC
PCMCIA devices.
Product Overview 1-21
Physical and Functional Overviews
All combinations of different Flash devices are supported by the PRP. You can use ATA Flash disks, Type 1 or Type 2 linear Flash memory cards, or a combination of the two. Each Flash disk slot has an ejector button for ejecting a card from the slot.
Note Type 1 and Type 2 linear Flash memory cards may not have the capacity to meet the
requirements of your configuration.
Asynchronous Serial Ports The PRP has two asynchronous serial ports, the console and auxiliary ports. These allow you to connect external serial devices to monitor and manage the system. Both ports use RJ-45 receptacles. The console port provides a data circuit-terminating equipment (DCE) interface for connecting a console terminal. The auxiliary port provides a data terminal equipment (DTE) interface and supports flow control. It is often used to connect a modem, a channel service unit (CSU), or other optional equipment for Telnet management.
Ethernet Ports The PRP includes two Ethernet ports, both using an 8-pin RJ-45 receptacle for either IEEE 802.3 10BASE-T (10 Mbps) or IEEE 802.3u 100BASE-TX (100 Mbps) connections.
Note The transmission speed of the Ethernet ports is auto-sensing by default and is user
configurable.
Line Cards The Cisco 12012 is shipped from the factory with up to 11 installed line cards that provide a variety of network media types (based on your order). The line cards are installed in slots 0 through 11 in the upper card cage and interface to each other and to the RP through the switch fabric (cards in the lower card cage). Vertical cable-management brackets attach to each line card to manage and organize the network interface cables.

Physical and Functional Overviews
Line cards installed in the Cisco 12012 support online insertion and removal (OIR), which means you can remove and replace a line card while the Cisco 12012 remains powered up.
To ensure adequate airflow through the upper card cage, empty card slots must have a card blank installed.
Caution
Note Detailed instructions for removing, replacing, and configuring the line cards
supported by the Cisco 12012 are contained in the configuration note for the individual line card.
Alarm Card The alarm card occupies a special slot (rightmost slot) in the upper card cage. The slot is labeled Alarm card, is physically narrower, and has a different backplane connector than the rest of slots in the upper card cage.
Product Overview 1-23
Physical and Functional Overviews
The alarm card has three primary functions:
•
Provides a visual display of three severity levels of alarms (critical, major, and minor) detected by the system through the MBus. The alarms can warn of an overtemperature condition on a component in the card cage assembly, a fan failure in a blower module, an overcurrent condition in a power supply, or an out-of-tolerance voltage on one of the cards in the upper or lower card cage. The threshold levels for triggering the different stages of alarms are set by software. The RP continuously polls the system for temperature, voltage, current, and fan speed values. If a threshold value is detected, the RP sets the appropriate severity level of alarm on the alarm card lighting one of three pairs of LEDs and energizing the appropriate alarm card relays activating any external audible or visual alarms.
•
Provides a connection point for the system to connect to two site-wide external alarm systems. Two redundant, 25-pin D-sub connectors on the alarm card faceplate are tied directly to the critical, major, and minor alarm relay normally open, normally closed, and common contacts. Only safety extra-low voltage (SELV) external alarm circuits can be attached to the two alarm card connectors. The external alarm can be visual or audible. Audible external alarms can be reset by the reset switch on the alarm card faceplate. Visual alarms are reset by software.
•
Provides visual status of the clock and scheduler cards and the switch fabric cards. Five pairs of LEDs (one pair for each slot in the lower card cage) provide a visual status of the switch fabric.
The alarm card faceplate contains the following connectors and indicators (see Figure 1-6):
•
Critical/Major/Minor LEDs—Three pairs of LEDs; two pairs are red, and one pair is amber. The LEDs are driven by MBus software. The LEDs give a visual indication of critical, major, and minor alarms detected by the system. The LEDs are paired for redundancy.
•
Audible alarm cutoff switch—A switch used to turn off an external audible alarm. It does not affect any visual (LED) alarms set on the alarm card. The audible alarm remains activated until the alarm condition is cleared or this button is pressed.
•
Alarm 1 and alarm 2 connectors—Two, 25-pin D-sub connectors. The alarm card relay contacts are tied to these two connectors. You can attach visual and audible alarm circuits to the alarm 1and alarm 2 connectors.

Note Only safety extra-low voltage (SELV) circuits can be connected to the alarm 1 and
alarm 2 connectors. Maximum rating for the alarm circuit is 2 amps, 50 volt-amp.
CSC/SFC LEDs—Five pairs of LEDs (one pair for each slot in the lower card cage) showing clock and scheduler card status and switch fabric card status. A green enabled LED indicates that the card in that slot has been detected by the system. A red fail LED indicates that the system has detected a fault in the card in that slot.

Clock and scheduler card and switch fabric card LEDs
Switch Fabric The heart of the Cisco 12012 is the switch fabric circuity, which provides synchronized gigabit speed interconnections for the line cards and the RP. The switch fabric circuitry is contained on two types of cards, a clock and scheduler card and a switch fabric card, which install in the five slots in the lower card cage. (See Figure 1-7.) A clock and scheduler card is installed in either slot 0 or slot 1 (CSC 0 or CSC 1) in the lower card cage; a switch fabric card is installed in slot 2, slot 3, or slot 4 (SFC 1, SFC 2, or SFC 3) in the lower card cage.
Product Overview 1-25
Physical and Functional Overviews
A system must have a one clock and scheduler card installed to operate. Both types of cards have a switching capacity of 15 Gbps. You can add switching capacity (up to 60 Gbps) and redundancy by increasing the number of switch cards (to a maximum of five cards) installed in your system.

Each clock and scheduler card or switch fabric card provides OC-12/STM-4 (622 Mbps) switching bandwidth for the system. By adding three more cards in the lower card cage, the bandwidth is increased to OC-48/STM-16 (2.4 Gbps). Table 1-5 lists the switch fabric bandwidth and the card configurations needed to support the bandwidth.

1. One clock and scheduler card must be installed in a system.
A minimally configured system has one clock and scheduler card installed. This configuration provides an OC-12/STM-4 bandwidth, but no switch fabric, clock, or scheduler redundancy. Adding a second clock and scheduler card provides fabric, clock, and scheduler redundancy, but no increase in bandwidth. Adding three switch fabric cards to a system with a single clock and scheduler card increases the system bandwidth to OC-48/STM-16, but no clock or scheduler redundancy. Adding a second clock and scheduler card to the system gives you OC-48/STM-16 bandwidth plus fabric, clock, and scheduler redundancy. The clock and scheduler card contains the following functionality:
•
System clock—Sent to all line cards, RP, and switch fabric cards. The system clock synchronizes data transfers between line cards or line cards and the RP through the switch fabric. In systems with redundant clock and scheduler cards, the two system clocks are synchronized so that if one system clock fails, the other clock takes over.
•
Scheduler—Handles requests from the line cards for access to the switch fabric. When the scheduler receives a request from a line card for switch fabric access, the scheduler determines when to allow the line card access to the switch fabric.
Product Overview 1-27
Physical and Functional Overviews
•
Switch fabric—Circuitry that carries the user traffic between line cards or between the RP and a line card. The switch fabric on the clock and scheduler card is identical to the switch fabric on the switch fabric card.
The switch fabric card contains only the switch fabric circuitry, which carries user traffic between line cards or between the RP and the line cards. The switch fabric card receives scheduling information and the system clock from the clock and scheduler card. The switch card is keyed to occupy slots 2, 3, and 4 (lower three slots) in the lower card cage. A minimally configured Cisco 12012 does not require a switch fabric card; however, to maximize the bandwidth and switching capacity of the Cisco 12012, three switch fabric cards must be installed. Status of the cards in the lower card cage is displayed by five pairs of LEDs (one pair for each card slot) on the alarm card in the upper card cage. Each pair of LEDs includes a green enable LED, which indicates the clock and scheduler card (CSC) or switch fabric card (SFC) is installed and operational, and a red fail LED, which indicates a fault has been detected on the card installed in that slot.
Power Supplies The power supply bay, located at the bottom of the card cage assembly, can accommodate up to four AC-input power supplies or two dual-width DC-input power supplies.
Do not mix power supplies in the Cisco 12012. In multiple power supply system configurations, all power supplies must be of the same type (four AC-input power supplies or two DC-input power supplies).
Caution
Note Detailed instructions for handling and replacing the Cisco 12012 power supplies are
contained in the configuration notes Cisco 12012 Gigabit Switch Router AC-Input Power Supply Replacement Instructions (Document Number 78-4334-xx) and Cisco 12012 Gigabit Switch Router DC-Input power Supply Replacement Instructions (Document Number 78-4330-xx). The appropriate configuration note accompanies each AC-input or DC-input power supply that is shipped from the factory as a FRU.

AC-Input Power Supply The AC-input power supply is a modular unit that measures 10 inches (25.4 cm) by 3.8 inches (9.6 cm) wide by 15 inches (38 cm) deep and weighs 18 lb (8.2 kg). (See Figure 1-8.) The Cisco 12012 requires two AC-input power supplies to operate. Installing one or two additional AC-input power supplies provides power supply redundancy and current sharing capability.
Warning AC operation requires a minimum configuration of two AC-input power
supplies.
An AC-input power supply has the following features:
•
A power factor corrector (PFC). Allows the power supply to accept source AC voltages from 180 to 264 VAC, single phase, 47 to 63 Hz. Each AC-input power supply requires a dedicated 20A service, North America; 10A or 16A, International.
• •
A handle. Provides a grip point for removing and replacing the power supply.
•
A power supply power cord appliance coupler. The main disconnect for the system. The power supply power switch engages a latch that secures the power supply in the power supply bay.
•
Two LEDs on the power supply faceplate. Indicate the following:
A captive screw at the bottom of the faceplate. Secures the power supply in the power supply bay.
— A green AC OK LED indicates that the source AC voltage is within the operational range of 200 to 264 VAC. The LED is on any time the power supply is connected to source AC and the power supply power switch is on. If the LED is off, a problem might be indicated. — A red output fail LED indicates that one or both of the power supply output voltages (+5 and –48 VDC) is out of tolerance. The LED flashes on and off for five seconds as a test of the LED when you first turn on the power supply.

•
Two LEDs on the power supply faceplate. The LEDs indicate the following:
A captive jackscrew. Seats and unseats the power supply in the backplane power supply connector and secures the power supply to the power supply bay.
— A green input OK LED indicates that the source DC voltage is within the operational range of –40.5 to –75 VDC. The LED is on anytime the power supply is connected to source DC and the power supply power switch is on. — A red output fail LED indicates that one or both of the power supply output voltages (+5 and –48 VDC) is out of tolerance. The LED will flash on and off for five seconds as a test of the LED when the power supply is first turned on.
•
Six threaded terminals—two each for negative (source DC), positive (source DC return), and ground. A hardwired source DC power cable is required from the site DC power source to the DC-input power supply. The DC power cable leads should be 4 American Wiring Gauge (AWG) high strand count wire. The lugs for connecting power cable leads to the power supply should be dual-hole, M6 terminal lugs with .625-inch (15.86-mm) centers.
•

Caution
Power Distribution The backplane distributes power in the Cisco 12012 through the backplane to all cards in the upper and lower card cages and to the two blower modules through two harnesses. (See Figure 1-10.) The power supplies convert either source AC or source DC into +5 VDC and -48 VDC. The +5 VDC goes directly to each card to power the MBus module. The –48 VDC feeds a DC-DC converter also on each card. The MBus module controls the DC-DC converter. When directed by the RP or by MBus software, the MBus module turns on the DC-DC converter; the –48 VDC is converted into +3.3 VDC and +5 VDC for use by the card. Power for the blower modules is supplied directly from the backplane through two harnesses mounted on the frame. An internal blower module controller card converts –48 VDC into a variable DC voltage which powers the blower module fans. An increase in the system ambient air temperature increases the voltage to the fans, increasing their speed.

Blower Module The Cisco 12012 has two blower modules; one is located above the upper card cage, and the second is located below the power supply bay. (See Figure 1-1.) The two blower modules maintain acceptable operating temperatures for the internal components by drawing cooling air through both card cages and the power supply bay. The blower module is a sheet metal enclosure containing three fans, a fan controller card, and two faceplate LEDs. (See Figure 1-11.) The top and bottom blower modules are identical and are interchangeable. Both blower modules have snap-on plastic front covers mounted over the blower module faceplates. Two blower module LEDs are visible through the front covers.

The blower modules draw room air in through an air filter on the front of the lower card cage (See Figure 1-12). The top blower module draws the air up through the upper card cage and out through exhaust vents on the back of the blower module; the bottom blower module draws the air down through the lower card cage and power supply bay and out through exhaust vents on the back of the blower module.

Product Overview 1-35
Physical and Functional Overviews
A blower module controller card in the blower module monitors and controls the operation of the three variable-speed fans. The variable-speed feature enables quieter operation by allowing the blower modules to operate at less than maximum speed when doing so provides adequate cooling to maintain an acceptable operating temperature inside the card cage assembly. Temperature sensors (two per card) monitor the internal air temperature. When the ambient air temperature is within normal operating range, the fans operate at their lowest speed, which is 55 percent of the maximum speed. If the air temperature inside the card cage assembly rises, fan speed increases to provide additional cooling air to the internal components. If the internal air temperatures continue to rise beyond the specified threshold, the system environmental monitor shuts down all internal power to prevent equipment damage from excessive heat. If the system detects that one of three fans within a blower module has failed, it displays a warning message on the console screen. In addition, the two remaining fans go to full speed to compensate for the loss of the one fan. If another fan fails, the system shut downs to prevent equipment damage. A handle on the blower module provides a grip point for removing and replacing a blower module. (See Figure 1-11.) Two LEDs (one green and one red), visible through the blower module front cover, provide blower module status. The green LED, when on, indicates all three fans are operating normally. The red LED should remain off during normal operation. If the red LED is on, a fan failure or other fault has been detected in the blower module. The fault can be one or more stopped fans or one or more fans running below speed, or the controller card has a fault.
Note The configuration note Cisco 12012 Gigabit Switch Router Blower Module

Air Filter The Cisco 12012 is equipped with a serviceable air filter mounted in a hinged tray located in front of the lower card cage. Do not run the Cisco 12012 without an air filter installed. You should inspect and clean the air filter once a month (more often in dusty environments). Procedures for vacuuming and replacing the air filter are contained in the section “Cleaning and Replacing the Air Filter Assembly” in the chapter “Maintaining the Cisco 12012.”
Cable-Management System The Cisco 12012 cable-management system organizes the interface cables entering and exiting the system, keeping them free of sharp bends (excessive bending in an interface cable can cause performance degradation) and out of the way. The Cisco 12012 cable-management system consists of two components: a horizontal cable-management tray attached to the frame above the upper card cage, and vertical cable-management brackets, one bracket per line card. (See Figure 1-13.) The horizontal cable-management tray keeps all of the interface cables organized as the cables enter the Cisco 12012 from either the left or right side, and directs them down through the bottom of the tray to the individual line cards. A vertical cable-management bracket attaches to each line card with two captive screws. Rubber clips on the bracket hold the interface cables in place, keeping the cables organized. On line cards with multiple ports, the vertical cable-management bracket keeps the interface cables organized when you remove and replace the line card. You can unplug the interface cables from the line card and keep cables clipped in the vertical cable-management bracket while you remove the bracket from the line card. Then, when you replace the line card, the interface cables are already broken out to the correct line card interface connectors.

Maintenance Bus The Cisco 12012 maintenance bus (MBus) and MBus modules manage all of the maintenance functions of the system. The Cisco 12012 MBus consists of two separate busses (providing MBus redundancy) that link all of the line cards, the RP, the switch fabric cards, the power supplies, and the blower modules. Each component contains an MBus module that allows the component to communicate over the MBus. The MBus module on each component is powered by +5 VDC directly from the power supply. The MBus modules perform the following functions:
•
Power-up/down control—Each MBus module directly controls the DC-DC converters on the component it is mounted on based on commands it receives from its on-board EPROM and from the master RP. Each MBus module is tied directly to +5 VDC from the power supply. When power is applied to the Cisco 12012, all MBus modules immediately power up. The MBus modules on the RP or clock and scheduler card immediately turn on the DC-DC converter, powering up the respective card. The line card MBus module waits to power up the line card until it receives a command from the master RP.
•
Device discovery—The RP can determine the system configuration using the MBus. A message is sent from the RP over the MBus requesting all installed devices to identify themselves. The response back provides slot number and card and component type.
•
Code download—A portion of the line card operating software can be downloaded from the RP to the line card over the MBus. Because the MBus is relatively slow compared to the switch fabric, only enough code is downloaded to the line card for it to access the switch fabric and complete the download process.
•
Diagnostics—The diagnostic software image is downloaded from the RP to the card under test.
Product Overview 1-39
System Specifications
•
Environmental monitoring and alarms—The MBus module on each component monitors that component’s environment as follows: — Line cards and the RP are monitored for temperature by two temperature sensors mounted on each card. The MBus module makes voltage adjustments through software for the +3.3- and +5-VDC DC-DC converters. — Clock and scheduler cards and switch fabric cards are monitored for temperature by two temperature sensors mounted on each card. The MBus module makes voltage adjustments through software for the +3.3- and +5-VDC DC-DC converters — Environmental monitoring includes voltage monitoring, temperature monitoring from two temperature sensors, and rotational speed sensing for each blower module fan.

Preparing for Installation This chapter provides specific information about preparing your site for the Cisco 12012. Included are safety guidelines, specific preparatory information, and tools and parts required to assure a successful installation of your Cisco 12012. The shipping package for Cisco 12000 series routers is engineered to reduce the potential of product damage associated with routine material handling experienced during shipment. To minimize potential damage to the product, transport these products in their Cisco-specified packagings. Failure to do so may result in damage to the router or degradation of its performance. Also, do not remove the GSR or Internet Router from its shipping container until you are ready to install it. The router should always be transported or stored in an upright position. Keep the router in the shipping container until you have determined where you will install it. Use the unpacking documentation included with the router when you unpack the Cisco 12012. Inspect all items for shipping damage. If anything is damaged, immediately contact a customer service representative. Sections in this chapter include the following:

Safety Recommendations Site Requirement Guidelines Tools for Installation Unpacking the Cisco 12012 Site Log
Preparing for Installation 2-1
Safety Recommendations
Before installing your Cisco 12012, you should consider power and cabling requirements that must be in place at your installation site, the equipment you will need to install the router, and the environmental conditions your installation site must meet to maintain normal operation. This chapter guides you through the process of preparing for your router installation.
Safety Recommendations The following guidelines will help to ensure your safety and protect the equipment. This list is not inclusive of all potentially hazardous situations, so be alert.
• •
Never attempt to lift an object that might be too heavy for you to lift by yourself.
• • •
Keep the work area clear and dust free during and after installation.
•
The Cisco 12012 operates safely when it is used in accordance with its marked electrical ratings and product usage instructions.
• •
Do not work alone if potentially hazardous conditions exist.
•
Review the safety warnings listed in the document Regulatory Compliance and Safety Information for the Cisco 12012 Gigabit Switch Router (Document Number 78-4347-xx) that accompanied your Cisco 12012 before installing, configuring, or maintaining the router.
Always disconnect the power source and unplug all power cables before working on the router.
Keep tools and router components away from walk areas. Do not wear loose clothing, jewelry (including rings and chains), or other items that could get caught in the router. Fasten your tie or scarf and sleeves.
The installation of your Cisco 12012 should be in compliance with national and local electrical codes: in the United States, National Fire Protection Association (NFPA) 70, United States National Electrical Code; in Canada, Canadian Electrical Code, part I, CSA C22.1; in other countries, International Electrotechnical Commission (IEC) 364, part 1 through part 7.
2-2 Cisco 12012 Gigabit Switch Router Installation and Configuration Guide
Safety Recommendations
•
Cisco 12012 routers with AC-input power supplies are shipped with a three-wire electrical grounding-type plug that will only fit into a grounding-type power outlet. This is a safety feature. The equipment grounding should be in accordance with local and national electrical codes.
•
Cisco 12012 routers configured with DC-input power supplies require a 60-ampere DC circuit breaker for the input DC power source. This circuit breaker should protect against short-circuit and overcurrent faults in accordance with United States National Electrical Code NFPA 70 (United States), Canadian Electrical Code, part I, CSA C22.1 (Canada) and IEC 364 (other countries).
•
Only a DC power source that complies with the safety extra-low voltage (SELV) requirements in UL950, CSA 950, EN 60950, and IEC950 can be connected to a Cisco 12012 DC-input power supply.
•
A Cisco 12012 configured with DC-input power supplies is to be installed in a restricted access area in accordance with Articles 110-16, 110-17, and 110-18 of the National Electric Code, ANSI/NFPA 70.
•
A Cisco 12012 configured with DC-input power supplies shall have a readily accessible disconnect device incorporated in the fixed wiring.
Lifting Guidelines A fully configured Cisco 12012 weighs approximately 380 lb (172 kg); it is not intended to be moved frequently. Before you install the router, ensure that your site is properly prepared so you can avoid having to move the Cisco 12012 later to accommodate power sources and network connections. Whenever you lift any heavy assembly, follow these guidelines:
•
Have a second person available to help lift the assembly; avoid lifting the assembly alone.
• •
Ensure that your footing is solid; balance the weight of the object between your feet. Lift the assembly slowly; never move suddenly or twist your body as you lift.
Preparing for Installation 2-3
Safety Recommendations
•
Keep your back straight and lift with your legs, not your back. If you must bend down to lift the assembly, bend at the knees, not at the waist, to reduce the strain on your lower back muscles.
•
Always disconnect all external cables before lifting or moving the Cisco 12012.
Caution To prevent damage, never attempt to lift or tilt the Cisco 12012 using the handles
on the blower modules or on the power supplies. These handles are not designed to support the weight of the Cisco 12012.
Safety with Electricity The line cards, redundant clock and scheduler cards, switch fabric cards, alarm card, blower modules, and redundant power supplies can be removed and replaced while the system is operating without presenting an electrical hazard or damage to the system. Follow these basic guidelines when working with any electrical equipment:
•
Before beginning any procedures requiring access to the interior of the Cisco 12012, locate the emergency power-off switch for the room in which you are working.
•
If an electrical accident occurs, proceed as follows: — Use caution; do not become a victim yourself. Disconnect power to the system. — If possible, send another person to get medical aid; otherwise, assess the condition of the victim and then call for help. — Determine if the person needs rescue breathing or external cardiac compressions, then take appropriate action.
• • •
Disconnect all power and external cables before installing or removing a router.
• •
Never install equipment that appears damaged.
Never assume that power has been disconnected from a circuit; always check. Do not perform any action that creates a potential hazard to people or makes the equipment unsafe.
Carefully examine your work area for possible hazards such as moist floors, ungrounded power extension cables, and missing safety grounds.
2-4 Cisco 12012 Gigabit Switch Router Installation and Configuration Guide
Safety Recommendations
In addition, use the guidelines that follow when working with any equipment that is disconnected from a power source, but still connected to telephone or network wiring:
• •
Never install telephone wiring during a lightning storm.
•
Never touch uninsulated telephone wires or terminals unless the telephone line has been disconnected at the network interface.
•
Use caution when installing or modifying telephone lines.
Never install telephone jacks in wet locations unless the jack is specifically designed for wet locations.
Preventing Electrostatic Discharge Damage Many router components are sensitive to damage from static electricity. Some components can be degraded by voltages as low as 30V. Conversely, static voltages as high as 35,000V can be generated just by handling plastic or foam packing material, or by sliding assemblies across plastic and carpets. Not exercising the proper electrostatic discharge (ESD) precautions can result in intermittent or complete component failures. To minimize the potential for ESD damage, observe the following guidelines:
• •
Always use an ESD wrist strap or ankle strap and ensure that it makes good skin contact.
•
Always place a card component-side up on an antistatic surface, in an antistatic card rack, or in a static shielding bag. If you are returning the item to the factory, immediately place it in a static shielding bag.
•
When installing a line card or RP, use the ejector levers to properly seat the card connectors in the backplane, then tighten both captive screws. These screws prevent accidental removal, provide proper grounding for the system, and help to ensure that the card connector is seated in the backplane.
When handling a removed line card, switch fabric card, or RP, make sure the equipment end of your ESD strap is attached to one of the two upper card cage ESD connection sockets or to bare metal on the frame. Avoid contact between the card and your clothing. The wrist strap only protects the card from ESD voltages on the body; EDS voltages on the clothing can still cause component damage.
Preparing for Installation 2-5
Site Requirement Guidelines
•
When removing line cards, clock and scheduler cards, switch fabric cards, or an RP, use the ejector levers to unseat the card connector from the backplane. Pull the metal card carrier out slowly, placing one hand along the bottom of the carrier to guide it straight out of the slot.
•
Handle line cards, clock and scheduler cards, switch fabric cards or an RP by the metal card carrier edges only; avoid touching the board or any connector pins.
For safety, periodically check the resistance value of the antistatic strap. The measurement should be between 1 and 10 megohms.
Caution
Laser Safety Single-mode style line cards for the Cisco 12012 are equipped with lasers, which emit invisible radiation. Do not stare into open line card ports. Observe the following warning to prevent eye injury.
Warning Because invisible laser radiation may be emitted from the aperture of the port
when no cable is connected, avoid exposure to laser radiation and do not stare into open apertures.

2-6 Cisco 12012 Gigabit Switch Router Installation and Configuration Guide
Site Requirement Guidelines
Rack-Mounting Guidelines Before installing the Cisco 12012 in telco-style or 19-inch equipment racks, consider the following general rack-mounting guidelines:
•
Install the frame in an enclosed rack only if the rack has adequate ventilation or an exhaust fan; use an open rack when possible.
•
A ventilation system that is too powerful in an enclosed rack can also prevent cooling by creating negative air pressure around the frame and redirecting the air away from the air intake vent. If necessary, operate the router with the rack door open or in an open rack.
• •
The correct use of baffles inside an enclosed rack can assist in cooling the router. Equipment located near the bottom of the rack can generate excessive heat that is drawn upward and into the intake ports of equipment above, leading to failures in the router. If the enclosed rack you are using does not have a ventilation fan, one should be installed.
The rack-mounting hardware included with the Cisco 12012 is suitable for most 19-inch equipment racks or telco-style racks. We strongly recommend a rack-mount installation for the Cisco 12012 because of size and weight considerations. Following are specific rack-mounting guidelines for the Cisco 12012:
•
The Cisco 12012 weighs approximately 380 lb (172 kg) fully configured. To keep the equipment rack center of gravity as low as possible, mount the router so that the bottom of the router frame is no higher than 10-inches (25.4-cm) from the floor.
•
If you use telco-style racks, be sure that the rack is bolted to floor. The frame mounts to the two rack posts, and the rest of the frame is cantilevered off of the posts. Ensure that the weight of the Cisco 12012 does not make the rack unstable. Some telco-style racks are also secured to ceiling brackets, if necessary, because of the weight of the equipment in the rack. Make sure that the rack you are installing the Cisco 12012 in is secured to the building structure.
•
The height of the Cisco 12012 frame is 57-inches (144.8-cm). Allow sufficient space in the rack for the frame.
•
To mount the router between two posts or rails, the inner clearance (the width between the inner sides of the two posts or rails) must be at least 17.5-inches (44.5-cm).
Preparing for Installation 2-7
Site Requirement Guidelines
•
Maintain at least a 6-inch (15.25-cm) clearance at the front and back of the router frame for cooling air intake and warm air exhaust. Avoid placing the router in an overly congested rack because the heated exhaust air from other equipment can enter the inlet air vents and cause an overtemperature condition inside the router.
• •
Allow at least 19 inches (48-cm) of clearance at the front of the rack for maintenance.
•
When mounting the router in a four-post or telco-style rack, be sure to use all of the screws provided to secure the frame to the rack posts.
Install and use the cable-management bracket included with the router to keep cables organized and out of the way of line cards, power supplies, and the blower modules. Consider the equipment and cabling that is already installed in the rack. Ensure that cables from other equipment will not impair access to the upper or lower card cage, or require you to disconnect cables unnecessarily to perform equipment maintenance or upgrades.

Site Requirement Guidelines
Airflow Guidelines The Cisco 12012 air circulation system consists of two blower modules: one mounted at the top of the frame (above the upper card cage) and the other mounted at the bottom of the frame (below the power supply bay). The blower modules maintain acceptable operating temperatures for the internal components by drawing cooling air in through a replaceable air filter and circulating the air through both card cages and the power supply bays. Observe the following guidelines when selecting a site to install the Cisco 12012:
•
The site should be as dust-free as possible. Dusty environments can clog the air filter, reducing the cooling airflow through the system. This can cause an overtemperature condition in the system.
•
Allow sufficient airflow by maintaining a minimum of 6 inches (15.2-cm) of clearance at both the inlet and exhaust openings on the frame. If the airflow is blocked or restricted, or if the inlet air is too warm, an overtemperature condition within the router can occur. Under extreme conditions, the environmental monitoring system will shut down the power to protect the system components.
Temperature and Humidity Guidelines Table 2-1 lists the operating and nonoperating environmental site requirements. The ranges listed are those within which the Cisco 12012 will continue to operate; however, a temperature measurement that is approaching a minimum or maximum indicates a potential problem. You can maintain normal operation by anticipating and correcting environmental anomalies before they approach critical values. The environmental monitoring functionality built into the Cisco 12012 protects the system and components from potential damage from overvoltage and overtemperature conditions. To assure normal operation and avoid unplanned maintenance, plan and prepare your site before you install the router.

Power Guidelines The Cisco 12012 can be configured with either AC-input or DC-input power supplies. The Cisco 12012 requires two AC-input power supplies or one DC-input power supply to operate. Site requirements differ depending on the type of source voltage. We recommend you follow these precautions and recommendations when planning power connections to the Cisco 12012:
•
Check the power at your site before installation and periodically after installation to ensure that you are receiving clean power. Install a power conditioner if necessary.
•
Install proper grounding to avoid damage from lightening and power surges.
Warning AC operation requires a minimum configuration of two AC-input power
supplies.
Preparing for Installation 2-11
Site Requirement Guidelines
AC-Powered Systems In sites where the Cisco 12012 operates with AC-input power supplies, observe the following guidelines:
•
The AC-input power supply operating between 185–264 VAC requires a minimum of 20-amp service, North America; 10-amp or 16-amp, International.
•
There are five styles of AC-input power supply power cords available (differing in plug type); make sure you have the correct style for your site. (See Figure 2-2 and Table 2-3.) All AC-input power supply power cords measure 14 feet (4.3 m).
• • •
Provide dedicated power sources for each power supply installed in the router. Install an uninterruptible power source where possible. Install proper grounding to avoid damage from lightening and power surges.

System Grounding Connection Guidelines Before you connect power or turn on your Cisco 12012, we strongly recommend that you provide adequate system ground for your router. System grounding (earth) receptacles are provided on the Cisco 12012. The grounding receptacles are located between the air filter tray and the power supply bays, on the card cage assembly mounting flange. To ensure the system grounding connection that you provide is adequate, you will need the following parts:
•
Two grounding lugs—Must have two M6 screw holes that have 0.625–0.75-inch (15.86–19.05-mm) spacing between them. The lug is similar to the type used for the DC-input power supply leads. (See Figure 2-3.) This grounding lug is not available from Cisco Systems; electrical-connector vendors, such as Panduit, provide this type of lug.
•
Four hex-head screws with locking washers—M6 (metric). These screws are not available from Cisco Systems; they are available from any commercial hardware vendor.
•
Two grounding wires—4 AWG recommended. The length of the wire depends on your router location and site environment. This wire is not available from Cisco Systems; it is available from any commercial cable vendor.
Site Wiring Guidelines Following are guidelines for setting up the plant wiring and cabling at your site. When planning the location of the new system, consider the distance limitations for signaling, electromagnetic interference (EMI), and connector compatibility, as described in the following sections. When wires are run for any significant distance in an electromagnetic field, interference can occur between the field and the signals on the wires. This fact has two implications for the construction of plant wiring:
• •
Bad wiring practice can result in radio interference emanating from the plant wiring. Strong EMI, especially when it is caused by lightning or radio transmitters, can destroy the signal drivers and receivers in the Cisco 12012, and can even create an electrical hazard by conducting power surges through lines and into equipment.
Preparing for Installation 2-15
Site Requirement Guidelines
Note To predict and remedy strong EMI, you might also need to consult experts in radio
frequency interference (RFI).
If you use twisted-pair cable in your plant wiring with a good distribution of grounding conductors, the plant wiring is unlikely to emit radio interference. If you exceed the recommended distances, use a high-quality twisted-pair cable with one ground conductor for each data signal when applicable. If wires exceed recommended distances, or if wires pass between buildings, give special consideration to the effect of a lightning strike in your vicinity. The electromagnetic pulse (EMP) caused by lightning or other high-energy phenomena can easily couple enough energy into unshielded conductors to destroy electronic devices. If you have had problems of this sort in the past, you may want to consult experts in electrical surge suppression and shielding. Most data centers cannot resolve the infrequent but potentially catastrophic problems just described without pulse meters and other special equipment. These problems can cost a great deal of time to identify and resolve, so take precautions by providing a properly grounded and shielded environment, with special attention to issues of electrical surge suppression.
SONET Connection Guidelines The SONET specification for fiber-optic transmission defines two types of fiber: single-mode and multimode. Modes can be thought of as bundles of light rays entering the fiber at a particular angle. Single-mode fiber allows only one mode of light to propagate through the fiber, while multimode fiber allows multiple modes of light to propagate through the fiber. Because multiple modes of light propagating through the fiber travel different distances depending on the entry angles, causing them to arrive at the destination at different times (a phenomenon called modal dispersion), single-mode fiber is capable of higher bandwidth and greater cable run distances than multimode fiber. The maximum distances for single-mode and multimode transmissions, as defined by SONET, are listed in Table 2-5. If the distance between two connected stations is greater than these maximum distances, significant signal loss can result, making transmission unreliable.

Single-mode

Multimode
Up to 1.5 miles (2.4 kilometers)
1. Table 2-5 gives typical results. You should use the power budget calculations to determine the actual distances.
Power Budget To design an efficient optical data link, evaluate the power budget. The power budget is the amount of light available to overcome attenuation in the optical link and to exceed the minimum power that the receiver requires to operate within its specifications. Proper operation of an optical data link depends on modulated light reaching the receiver with enough power to be correctly demodulated. Attenuation, caused by the passive media components (cables, cable splices, and connectors), is common to both multimode and single-mode transmission. The following variables reduce the power of the signal (light) transmitted to the receiver in multimode transmission:
•
Chromatic dispersion (spreading of the signal in time because of the different speeds of light wavelengths)
•
Modal dispersion (spreading of the signal in time because of the different propagation modes in the fiber)
Attenuation is significantly lower for optical fiber than for other media. For multimode transmission, chromatic and modal dispersion reduce the available power of the system by the combined dispersion penalty (in decibels [dB]). The power lost over the data link is the sum of the component, dispersion, and modal losses. Table 2-6 lists the factors of attenuation and dispersion limit for typical fiber-optic cable.

Approximating the Line Card Power Margin The LED used for a multimode transmission light source creates multiple propagation paths of light, each with a different path length and time requirement to cross the optical fiber, causing signal dispersion (smear). Higher order mode loss (HOL) results from light from the LED entering the fiber and being radiated into the fiber cladding. A worst-case estimate of power margin (PM) for multimode transmissions assumes minimum transmitter power (PT), maximum link loss (LL), and minimum receiver sensitivity (PR). The worst-case analysis provides a margin of error, although not all of the parts of an actual system will operate at the worst-case levels. The power budget (PB) is the maximum possible amount of power transmitted. The following equation lists the calculation of the power budget: PB = PT – PR PB = –18.5 dBm –(– 30 dBm) PB = 11.5 dB The power margin calculation is derived from the power budget and subtracts the link loss, as follows: PM = PB – LL If the power margin is positive, as a rule, the link will work. Table 2-7 lists the factors that contribute to link loss and the estimate of the link loss value attributable to those factors.

Multimode Power Budget Example with Sufficient Power for Transmission The following is an example calculation for a multimode power budget based on the following variables: Length of multimode link = 3 kilometers (km) 4 connectors 3 splices Higher order loss (HOL) Clock recovery module (CRM) Estimate the power budget as follows: PB = 13 dB – 3 km (1.0 dB/km) – 4 (0.5 dB) – 3 (0.5 dB) – 0.5 dB (HOL) – 1 dB (CRM) PB = 13 dB – 3 dB – 2 dB – 1.5 dB – 0.5 dB – 1 dB PB = 5 dB The value of 5 dB indicates that this link would have sufficient power for transmission.
Multimode Power Budget Example of Dispersion Limit Following is an example with the same parameters as the previous example, but with a multimode link distance of 4 km: PB = 13 dB – 4 km (1.0 dB/km) – 4 (0.5 dB) – 3 (0.5 dB) – 0.5 dB (HOL) – 1 dB (CRM) PB = 13 dB – 4 dB – 2 dB – 1.5 dB – 0.5 dB – 1 dB PB = 4 dB The value of 4 dB indicates that this link would have sufficient power for transmission; however, due to the dispersion limit on the link (4 km x 155.52 MHz > 500 MHzkm), this link would not work with multimode fiber. In this case, single-mode fiber would be the better choice.
2-20 Cisco 12012 Gigabit Switch Router Installation and Configuration Guide
Site Requirement Guidelines
Single-Mode Transmission The single-mode signal source is an injection laser diode. Single-mode transmission is useful for longer distances because there is a single transmission path within the fiber and smear does not occur. In addition, chromatic dispersion is also reduced because laser light is essentially monochromatic. The maximum overload specification on the single-mode receiver is –14 dBm. The single-mode receiver can be overloaded when using short lengths of fiber because the transmitter can transmit up to –8 dB. The receiver could be overloaded at –14 dB, but no damage will result. To prevent overloading the receiver connecting short fiber links, insert a 5 to 10 dB attenuator on the link between any single-mode SONET transmitter and the receiver.
SONET Single-Mode Power Budget Example The following example of a single-mode power budget is of a two buildings, 11 kilometers apart, connected through a patch panel in an intervening building with a total of 10 connectors. Length of single-mode link = 11 km 10 connectors Estimate the power budget as follows: PB = 11.5 dB – 11 km (0.5 dB/km) – 10 (0.5 dB) PB = 11.5 dB – 5.5 dB – 5 dB PB = 1 dB The value of 1 dB indicates that this link would have sufficient power for transmission and is not in excess of the maximum receiver input power.

Tools for Installation
Using Statistics to Estimate the Power Budget Statistical models more accurately determine the power budget than the worst-case method. Determining the link loss with statistical methods requires accurate knowledge of variations in the data link components. Statistical power budget analysis is beyond the scope of this document. For further information, refer to UNI Forum specifications, ITU-T standards, and your equipment specifications.

Installing a Cisco 12012 This chapter provides the procedures for installing the Cisco 12012 and contains the following sections:
• • • • • • • •
Installing the Brace Bar Removing the Cisco 12012 Components before Installing the Frame Rack-Mounting the Frame Reinstalling the Cisco 12012 Components after Installing the Frame Connecting Line Card Cables Connecting Route Processor Cables Connecting Alarm Card Cables Connecting Power
Note You must install the Cisco 12012 in a rack; either a telco-style or a four-post unit.
The Cisco 12012 is not designed to be installed as a shelf-mounted or a free-standing system.
Installing a Cisco 12012 3-1
Before you install your Cisco 12012, your installation site should already be prepared. Ensure that you have planned a compatible location for the Cisco 12012 and that you have considered the following:
•
The location does not block the cooling air intake (front of the system) and exhaust vents (rear of system). There must be at least 6 inches (15.8 cm) of clearance in the rack for the air intake and exhaust vents.
• •
The location is a temperature-controlled, air-conditioned, dust-free area.
• •
The proper source voltage (AC or DC) receptacles have been provided.
You have checked the power cables and power supplies for compatibility with your power service; check the labels on the equipment and ensure that the power service at your site is suitable for the Cisco 12012.
Maintain at least 24 inches (61 cm) of clearance in front of the frame for working with line cards, blower modules, power supplies, or attaching network interface cables or equipment.
Warning The Cisco 12012 must be installed in a rack that is secured to the building
structure.
To prevent system problems, do not mix power supply input types in the Cisco 12012 router. All power supplies installed in a router must be either AC-input or DC-input.
Caution
The Cisco 12012, fully configured, can weigh 380 lb (172.3 kg). The system installation process is structured to reduce the weight of the system by removing components from the card cage assembly and the frame, then installing the empty frame in the rack, and finally, reinstalling all of the components in the card cage assembly and the frame. To make the installation process easier, reduce the weight of the system. The installation procedure requires you to remove all of the components from the card cage assembly and the frame, then install the empty frame in the rack, and finally reinstall all of the components in the card cage assembly and the frame.
3-2 Cisco 12012 Gigabit Switch Router Installation and Configuration Guide
Installing the Brace Bar
Installing the Brace Bar An optional brace bar is shipped with every Cisco 12012 as part of the accessory kit. You install the brace bar across the front of the rack to support the frame while you secure the frame is in the rack.
The brace bar can only support the weight of an empty frame. It is not designed to support the full weight of the Cisco 12012.
Caution
This is an optional procedure; you can install the Cisco 12012 in the rack without a brace bar. If you choose not to use the brace bar, proceed to the next section “Removing the Cisco 12012 Components before Installing the Frame.” Perform the following steps to install the brace bar (see Figure 3-1): Step 1
Determine the proper height to install the brace bar in the rack. We recommend that you install the brace bar not more than 12 inches (30.5 cm) above the floor to maintain a low center of gravity for the system.
Step 2
Position the brace bar between the front posts of a four-post rack or telco-style rack; make sure that the bar is level.
Step 3
Secure the brace bar to the rack using the two screws provided in the accessory kit.

Removing the Cisco 12012 Components before Installing the Frame To make the frame installation process easier, reduce the total weight of the system. The installation process requires you to remove all of the components from the card cage assembly and the frame, then install the empty frame in the rack, and finally reinstall all of the components in the card cage assembly and the frame. Before you can remove the Cisco 12012 components, you must position the Cisco 12012, mounted on its shipping pallet (with the shipping container disassembled), as close to the installation site as possible. A Cisco 12012 system configured for either source AC or source DC power is shipped with power supplies installed in the power supply bay. Redundant AC-input power supplies (third and fourth power supplies) are shipped in a large cardboard box on the front of the pallet. Procedures in the following sections provide the steps for removing the Cisco 12012 components:

Removing the Cards from the Upper Card Cage The upper card cage has 12 user-configurable slots (numbered 0 through 11, from left to right) that can support a combination of line cards and an RP. The upper card cage also has a non-configurable slot (rightmost slot, labeled Alarm card) for an alarm card. To reduce the weight of the card cage assembly, you need to remove the cards from slots 0 through 11.
Note You do not need to remove any card blanks or the alarm card from the upper card
cage.
Note Each line card has a vertical cable-management bracket attached to it that manages
the distribution and routing of the network interface cables from the line card to the external network. Leave the vertical cable-management bracket attached to the line card when you remove the line cards. The RP and alarm card do not have vertical cable-management brackets.
Perform the following steps to remove a card from the upper card cage: Step 1
Attach an ESD wrist strap to your wrist and to one of the two ESD connection sockets located on the front edges of the upper card cage or to bare metal on the frame.
Step 2
Proceeding from left to right, identify each card and note its slot number on a piece of paper. (This step will make reinstallation easier and will ensure that you reinstall cards in their proper slots.)
Note Line cards and an RP are installed in slots 0 through 11 in the upper card
cage.

Removing the Cards from the Lower Card Cage The lower card cage is located below the upper card cage, behind the air filter tray on the front of the card cage assembly. Mounted in the lower card cage is an air deflector, which directs airflow in the card cage assembly. The lower card cage has five keyed, color-coded, horizontal card slots for the clock and scheduler cards and switch fabric cards. Clock and scheduler cards (light blue) are installed in the upper two card slots (slot 0 and slot 1); switch fabric cards (magenta) are installed in the lower three slots (slot 2, slot 3, and slot 4). When you want to remove or install either type of card, you must first open the air filter tray and pivot the air deflector up, out of the way to gain access to the lower card cage. Perform the following steps to access the lower card cage and remove the clock and scheduler cards and switch fabric cards: Step 1
Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets located on the front edges of the upper card cage or to bare metal on the frame.
Step 2
To gain access to the lower card cage, loosen the two captive screws at the top of the air filter tray and pivot the tray down, away from the lower card cage. (See Figure 3-6.)

Installing a Cisco 12012 3-27
Reinstalling the Cisco 12012 Components after Installing the Frame
Reinstalling the Cards in the Lower Card Cage The lower card cage slots are keyed and color coded; clock and scheduler cards are installed in the upper two slots (light blue), and switch fabric cards are installed in the lower three slots (magenta). Perform the following steps to reinstall the clock and scheduler cards and switch fabric cards in the lower card cage: Step 1
Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets located on the front edges of the upper card cage or to bare metal on the frame.
Step 2
To access the lower card cage, loosen the two captive screws at the top of the air filter tray and pivot the tray down, away from the lower card cage. (See Figure 3-6.)
To prevent damage, do not place any tools on the air filter tray or inside the lower card cage. Damaging the honeycomb screen on the air filter tray or in the lower card cage could restrict the air flow causing an overtemperature condition in the Cisco 12012.
Caution
Step 3
To access the card slots in the lower card cage, you must first move the air deflector out of the way. Lift the air deflector up and secure it to the top of the lower card cage by turning the air deflector latch knob counterclockwise. (See Figure 3-7.)
Step 4
Select a card from the antistatic mat. Determine which card slot the card should be installed in by checking the color of the label attached to the edge of the card carrier (near the ejector levers). Light blue labels identify clock and scheduler cards; magenta labels identify switch fabric cards.
Note There are alignment grooves on both sides of each slot in the lower card
cage. When you reinstall a card in the lower card cage, make sure you align the card correctly with both edges of the card carrier in the slot grooves.
3-28 Cisco 12012 Gigabit Switch Router Installation and Configuration Guide
Reinstalling the Cisco 12012 Components after Installing the Frame
Step 5
Grasp the card carrier edge with one hand and place your other hand under the carrier to support and guide it into the correct slot. Slide the card halfway into the slot. Avoid touching the card circuitry or any connectors.
Note Make sure the card is centered in the slot. To do so, apply even pressure
to both sides of the card carrier as you slide the card into the slot. Also, lower card cage cards have guide pins that make initial contact with the backplane connector as you slide a card in its slot. After the guide pins make contact, continue pushing on the card carrier until the card ejector levers start pivoting forward. Then use the ejector levers to fully insert the card in the backplane connector.
Step 6
Pivot the card ejector levers out ninety degrees away from the sides of the card carrier.
Step 7
Continue sliding the card into the card cage slot until the card ejector levers engage the alignment grooves in the card cage slot.
Step 8
Grasp both card ejector levers and pivot them outward (toward the sides of the card cage) until they are parallel to the card carrier edge to seat the card in the backplane connector. Snap the card ejector levers into the sides of the card carrier.
Repeat Step 4 through Step 8 for the rest of the cards in the lower card cage, then proceed to Step 9. Step 9
Release the air deflector latch and lower the air deflector down to its stops.
Step 10
Pivot the air filter tray up so that it is flush with the front of the lower card cage and tighten the two captive screws.
This completes the procedures for reinstalling components in the upper and lower card cages.

Connecting Line Card Cables
Connecting Line Card Cables This section contains the instructions for placing the network interface cables in the Cisco 12012 cable-management system and attaching the network interface cables to the line card ports. The Cisco 12012 cable-management system consists of two components: a horizontal cable-management tray mounted directly above the upper card cage, and vertical cable-management brackets that attach to each line card. Additional line card information is contained in the respective configuration note for each line card. For example, if you are connecting the cables for a Quad OC-3c/STM-1c Packet-Over-SONET (POS) line card, refer to the configuration note Quad OC-3c/STM-1c Packet-Over-SONET Line Card Installation and Configuration (Document Number 78-4333-xx), which accompanies every Quad OC-3c/STM-1c POS line card that is shipped from the factory as a FRU or as an installed item in a Cisco 12012. Perform the following steps to install the network interface cables in the Cisco 12012 cable-management system and connect the network interface cables to the line cards: Step 1
Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets on the front edges of the upper card cage or to bare metal on the frame.
Step 2
Proceeding from left to right in the upper card cage, identify the network interface cables that attach to the first line card.
Step 3
One network interface cable at a time, carefully route the identified cable through the horizontal cable-management tray and down to the line card interface port. (See Figure 3-13.)
Note On line cards with multiple ports, route and connect network interface
cables to the line cards starting at the bottom line card port and working up.

Connecting Route Processor Cables
Connecting Route Processor Cables The console and auxiliary ports for the Cisco 12012 are located on the RP. The GRP has an optional Ethernet port and the PRP has two Ethernet ports. This section contains connection equipment and pinout information for the console, auxiliary, and Ethernet ports on the GRP and PRP.
GRP Console and Auxiliary Port Connection Equipment The GRP has two EIA/TIA-232 ports: a DCE-mode console port and a DTE-mode auxiliary port. The console port is a DCE DB-25 receptacle for connecting a console terminal, which you need to configure the Cisco 12012. The auxiliary port is a DTE DB-25 plug for connecting a modem or other DCE device (such as a channel service unit/data service unit (CSU/DSU) or other router) to the Cisco 12012 (see Figure 3-14).

Connecting Route Processor Cables
Note The console and auxiliary ports are asynchronous serial ports; any devices
connected to these ports must be capable of asynchronous transmission. (Asynchronous is the most common type of serial device; for example, most modems are asynchronous devices.)
Note In order to maintain Class B EMI compliance, shielded cables must be used on the
console and auxiliary ports of the GRP= and GRP-B=. An updated version of the GRP-B= board (Rev. F0) is available. This version does not require shielded cables for Class B compliance.
Before connecting a terminal to the console port, check your terminal’s documentation to determine the baud rate of the terminal you plan to use. The baud rate of the terminal must match the default rate (9600 baud). Set up the terminal as follows: 9600 baud, 8 data bits, no parity, 2 stop bits (9600 8N2). You need an EIA/TIA-232 DCE console cable to connect the terminal to the console port. Cisco Systems does not provide console and auxiliary port cables; cables are available from commercial sources.
Note You must provide the EIA/TIA-232 cables to connect the terminal to the GRP
console port or other devices to the auxiliary port. Cisco Systems does not provide console and auxiliary port cables; cables are available from other vendors. For compliance with GR-1089 (intra-building surge), you must use shielded cables on the GRP console and auxiliary ports. Because the connectors on some standard cables are tall enough to interfere with the front covers installed on the card cages, Cisco includes a lower-profile cable adapter that permits you to connect a flat cable with modular RJ-45 plugs to the GRP console port.
For console and auxiliary port pinouts, refer to Table 3-1 and Table 3-2, respectively.

GRP Ethernet Connection Equipment The Ethernet port on the GRP has both a media independent interface (MII), 40-pin, D-shell type receptacle and a media dependent interface (MDI) RJ-45 receptacle that are capable of data transmission rates from 10 and 100 megabits per second (Mbps). (See Figure 3-15.)
Note At the auto-sensed data transmission rate of 100 Mbps, the Ethernet port provides
maximum usable bandwidth that is less than 100 Mbps; a maximum usable bandwidth of approximately 20 Mbps should be expected from either the RJ-45 or MII connections. Transmission speed is determined by the network to which the Ethernet interface is connected and is not user-configurable.

Both the MII and RJ-45 receptacles support IEEE 802.3u Ethernet interfaces compliant with the 100Base-TX and 10Base-T standards. The MII receptacle requires an external transceiver that permits connection to multimode fiber for 100Base-FX or 100Base-T4 physical media. Only one Ethernet receptacle, either RJ-45 or MII, can be used at a time. Two LEDs on the GRP faceplate show which Ethernet receptacle is active.
Note The Ethernet port can use either unshielded twisted-pair or screened twisted-pair
cables. In sites where extremely high immunity to noise is required, screened twisted-pair cable is recommended.
Depending on the type of media you use between the MII receptacle and your switch or hub, the network side of your 100-Mbps transceiver should be appropriately equipped with ST-type connectors (for optical fiber), BNC connectors, and so forth. Figure 3-16 shows the pin orientation of the female MII receptacle on the Ethernet port.

PRP Console and Auxiliary Port Connection Guidelines The system console port on the PRP is a DCE RJ-45 receptacle for connecting a data terminal, which you must configure. The console port is labeled Console, as shown in Figure 3-18. Before connecting the console port, check your terminal’s documentation to determine the baud rate of the terminal you plan to use. The baud rate of the terminal must match the default baud rate (9600 baud). Set up the terminal as follows: 9600 baud, 8 data bits, no parity, and 2 stop bits (9600, 8N2). The console port requires a straight-through RJ-45 cable.

PRP Ethernet Connection Equipment There are two RJ-45 Ethernet interface receptacles on the PRP, providing media-dependent interface (MDI) Ethernet ports. These connections support IEEE 802.3 and IEEE 802.3u interfaces compliant with 10BASE-T and 100BASE-TX standards. The transmission speed of the Ethernet ports is auto-sensing by default and is user configurable. The RJ-45 receptacles on the PRP provide two physical connection options for Ethernet interfaces. RJ-45 cables are not available from Cisco Systems; they are available from outside commercial cable vendors. To connect cables to the PRPs Ethernet interfaces (ports labeled ETH0 and ETH1), attach the Category 5 UTP cable directly to a RJ-45 receptacle on the PRP. The Ethernet interfaces on the PRP are end-station devices, not repeaters; therefore, you must connect an Ethernet interface to a repeater or hub.
Note Only connect cables that comply with EIA/TIA-568 standards. (See Table 3-8 and
Table 3-9 for cable recommendations and specifications.)
Caution The Ethernet ports are primarily used as a Telnet port into the Cisco 12000 series
Internet Router, and for booting or accessing Cisco IOS software images over a network to which an Ethernet port is directly connected. Cisco Express Forwarding (CEF) functions are switched off by default for security reasons. Cisco strongly cautions you to consider the security implications of switching on CEF routing functions on these ports.

Figure 3-19 shows an example of the functionality of an Ethernet port. In this example, you cannot access Network 2.0.0.0 via the Ethernet port (ETH0) on the PRP in Router A; you can only access the hosts and Router C, which are in Network 1.0.0.0. (See dotted arrows in Figure 3-19.) To access Network 2.0.0.0 from Router A, you must use an interface port on one of your line cards (in this example, a Packet-over-SONET (POS) line card in Router A) to go through Router B, through Router C, and into Network 2.0.0.0. (See solid arrows in Figure 3-19.)

Connecting System Grounding
Connecting System Grounding Before you connect power or turn on power to the Cisco 12012, we strongly recommend that you provide an adequate system grounding (earth) connection for your system. Two system grounding receptacles are provided on each Cisco 12012. (See Figure 3-24.) To ensure the system grounding connection that you provide is adequate, you will need the following parts:
•
Two grounding lugs—Must have two M6 holes that have a 0.625-inch to 0.75-inch (15.86-mm to 19-mm) spacing between them and a wire receptacle large enough to accept a 4-AWG, or larger, multistrand copper wire. This type of grounding lug is not available from Cisco Systems; electrical-connector vendors, such as Panduit, provide this type of grounding lug.
•
Four M6 or equivalent hex-head bolts with locking washers and nuts—This mounting hardware is not available from Cisco Systems; it is available from any commercial hardware vendor.
•
Two grounding wires—4 AWG (0.204-inch [5.18-mm] diameter) or larger. The actual wire diameter and length are dependent on your router location and site environment. This wire is not available from Cisco Systems; it is available from any commercial cable vendor.

Connecting Power
Connecting Power This section provides procedures for installing an AC-input power supply and a DC-input power supply. Select the procedure appropriate for your system.
Note Detailed instructions for handling and replacing the Cisco 12012 power supplies are
contained in the configuration notes Cisco 12012 Gigabit Switch Router AC-Input Power Supply Replacement Instructions (Document Number 78-4334-xx) and Cisco 12012 Gigabit Switch Router DC-Input Power Supply Replacement Instructions (Document Number 78-4330-xx). One of these configuration notes accompanies the respective power supply shipped from the factory as a FRU. These configuration notes are also available on the Documentation CD and on Cisco Connection Online (CCO).
Caution
Do not mix AC-input and DC-input power supplies in a Cisco 12012.
To maintain agency compliance requirements and meet EMI emissions standards in the Cisco 12012 with fewer than four AC-input power supplies or only one DC-input power supply, power supply blanks must be installed in any empty power supply bays. Do not remove a blank from the bay except to install a power supply.
Caution
Note AC-input power supplies and DC-input power supplies differ in width. An AC-input
power supply occupies only one power supply bay. A DC-input power supply is twice as wide and occupies two power supply bays.
Warning AC operation requires a minimum configuration of two AC-input power
supplies.

Connecting Power
Reinstalling an AC-Input Power Supply This section provides the procedure for reinstalling an AC-input power supply in the Cisco 12012. The Cisco 12012 power supply bays are labeled A1, A2, B1, B2 (from left to right). You should reinstall the AC-input power supplies in the bays in the following order: A1, B1, A2, and B2. Perform the following steps to reinstall an AC-input power supply:
The AC-input power supply weighs 18 lb (8 kg). Use two hands when handling the power supply.
Caution
Step 1
Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets located on the front edges of the upper card cage or to bare metal on the frame.
Step 2
Verify that the power supply power switch is in the STANDBY position.
To prevent damaging the power supply backplane connector, do not use excessive force when installing a power supply into the bay.
Caution
Note Any bay that does not have a power supply installed must have a power
supply blank installed to maintain airflow and for EMI considerations.
Step 3
Using two hands to support and guide the power supply, slide it into the vacant bay. Push the power supply all the way into the bay until the faceplate is flush with the front of the bay.
Note All electrical connections between the power supply and the backplane
are made automatically when the power supply is fully inserted in the power supply bay.

Clip the spring clip over the power cord plug to secure the plug in place. (See Figure 3-26c.)
Step 8
Connect the other end of the AC power cord to the source AC receptacle. (See Figure 3-26d.)
Note We recommend attaching each AC-input power supply to an independent
power source for full redundancy. We also recommend that you use an uninterruptable power source (UPS) to protect against power failures at your site. Each AC-input power supply operates between 200 VAC and 240 VAC, and requires a dedicated 20A service for North American use and 10A or 16A for international use.
Step 9
Verify that the source AC circuit breaker servicing the source AC receptacle is switched on.
Note Do not turn the power supply power switch ON (|) at this time.
Repeat Step 2 through Step 9 for the rest of the AC-input power supplies. This completes the Cisco 12012 hardware installation procedure. Proceed to the next chapter for procedures for observing system startup and performing a basic configuration.

The card cage assembly power supply bays are labeled A1, A2, B1, and B2 (from left to right). If your Cisco 12012 is configured with only one DC-input power supply, reinstall the power supply in power supply bays A1/A2. If your Cisco 12012 is configured with a second (redundant) DC-input power supply, reinstall it in power supply bays B1/B2.
Note Unoccupied power supply bays must have power supply blanks installed to maintain
proper airflow and for EMI considerations.
Perform the following steps to reinstall a DC-input power supply:
The DC-input power supply weighs 19 lb (8.3 kg). Use two hands when handling the power supply.
Caution
Step 1
Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets located on the front edges of the upper card cage or to bare metal on the frame.
Step 2
Verify that the DC-input power supply power switch is turned OFF (O).

Connecting Power
Before proceeding to the next step, verify that the source DC circuit breaker servicing the source DC power cable you are attaching to the DC-input power supply is in the OFF position. Also verify that the power switch on the DC-input power supply is OFF (O). As an additional check, measure the voltages across the DC power cable leads you intend to attach to the power supply. All readings should be zero volts.
Caution
Step 6
Thread the source DC power cable leads up underneath the power supply handle. Allow sufficient slack in the power cable for strain relief.
Note The color coding of the source DC power cable leads to the DC-input
power supply depends on the color coding of the site DC power source. Typically, green or green/yellow is used for ground. Since there is no color code standard for the DC wiring, you must ensure that the proper polarity is connected to the DC-input power supply. In some cases, the source DC cables might have a (+) or a (–) label. This is a relatively safe indication of the cable polarity.
Warning When installing the unit, the ground connection must always be made first and
disconnected last.
Step 7
Remove the nut and locking washer from each of the six power supply threaded terminals on the front of the power supply. Attach the source DC power cable lug to the power supply terminal in the following order (see Figure 3-29):
• • •

Step 8
Thread the power supply circuit breaker external alarm leads (if present) up through the power supply handle and attach them to the circuit breaker alarm terminal block on the power supply faceplate. (Some sites might not be equipped with a power supply circuit breaker external alarm.)
Step 9
Position the source DC power cable leads underneath the power supply handle on the power supply faceplate in the following order from left to right: negative (–), positive (+), and ground.
Step 10
Place the DC power cable bracket over the power cable leads and secure the cable leads and the cable bracket to the power supply faceplate with the two screws that you removed earlier.
Step 11
Verify that the source DC wiring from the source DC breaker to the power supply is correct and that the terminal connections on the power supply are correct and tight.
Note Verify the source DC cable connections to the DC-input power supply
with a voltmeter. Always connect positive (+) leads to positive (+) terminals and negative (–) leads to negative (–) terminals on the power supply.
Step 12
Position the power supply front cover so that the keyholes are over the two standoff screws on the power supply faceplate. Slide the cover down slightly to engage the two screws and secure it in place by tightening the two screws.
To prevent damaging the backplane power connector, do not use excessive force when sliding the power supply into the bay.
Caution
Note The first DC-input power supply is installed in power supply bays A1/A2;
the second DC-input power supply is installed in power supply bays B1/B2.

Observing System Startup and Performing a Basic Configuration This chapter describes the initial system startup process, and provides the procedures for performing a basic configuration of your Cisco 12012 Gigabit Switch Router (GSR). This chapter contains the following sections:
• • • • •
Starting the System and Observing Initial Conditions Configuring the Cisco 12012 Implementing Other Configuration Tasks What To Do Next? If You Need More Configuration Information
Note The primary goal of this chapter is to provide you with the necessary information to
configure your system so that you can access your network or access your Cisco 12012 remotely via Telnet. Complex configuration procedures are beyond the scope of this text, and can be found in the configuration publications listed in the section “If You Need More Configuration Information.” Also refer to the configuration notes that accompanied the line cards installed in your system.
Observing System Startup and Performing a Basic Configuration 4-1
Checking Connections in Preparation for System Startup
Checking Connections in Preparation for System Startup Before you start your system, perform a final check of all connections to ensure they are secure, as follows:
•
All line cards are inserted all the way into the slots in the upper card cage, and all captive installation screws are tightened.
• •
All cards in the lower card cage are inserted all the way into the lower card cage slots.
•
All power supplies have power cables connected; then, the opposite end of all power cables are connected to the appropriate power source.
•
The console terminal is connected to the console port, configured for the appropriate communications parameters, and turned on. To perform the initial configuration of a Cisco 12012 from a console, you need to connect a terminal connection to the Route Processor (RP) console port.
•
The Flash memory card that shipped with your system must be installed in PCMCIA slot 0 of the RP.
All interface cable connections are securely attached; use cable strain relief where provided.
Note By default, a Flash memory card with a valid Cisco IOS software image ships
installed in PCMCIA slot 0 of the RP. Also, by default, the SW configuration register is set to 0x0102; therefore, the system will automatically boot from the Cisco IOS software image in the Flash memory card. Also, new Flash memory cards must be formatted before you can use them. After you start the system, refer to the section “Formatting a Flash Memory Card,” later in this chapter.
After you complete the final check, proceed to the following section to start up the system.
4-2 Cisco 12012 Gigabit Switch Router Installation and Configuration Guide
Starting the System and Observing Initial Conditions
Starting the System and Observing Initial Conditions This section describes the initial system startup processes and procedures. Use the following procedure to start your system: Step 1
Turn ON each installed power supply by turning its system power switch to the ON (|) position. For AC-input power supplies, the green AC OK LED should go on. For DC-input power supplies, the green input OK LED should go on.
Step 2
Listen for the blower modules; you should immediately hear them operating. In a noisy environment the blower modules might be difficult to hear; therefore, place your hand in front of the exhaust vents to verify that the blower modules are operating.
Step 3
During the RP boot process, observe the RP alphanumeric LED displays, which are located at the end of the RP. (See Figure 4-1.) Each 4-digit display is capable of showing system messages and displays a sequence that is similar to that shown in Table 4-1.

The line card is enabled and ready for use.
1. The sequence shown in Table 4-2 might occur too quickly for you to view; therefore, this sequence is provided as a baseline for how the line cards should function at startup. 2. The fabric downloader loads the Cisco IOS software image onto the line card.
Note If you have a Flash memory card installed in PCMCIA slot 0, the Flash memory card
contains a valid, bootable Cisco IOS software image, and the software configuration register is set to 0x0102, the system will automatically boot this Cisco IOS software image. The system then enters the setup facility where you will be prompted to perform a basic configuration of the system (as shown in Step 6). Otherwise, the system will enter the ROM monitor, and the ROM monitor prompt will appear (>). In this case, you must proceed to Step 5.
Step 5
If the ROM monitor prompt (>) appears, you then have to boot the Cisco IOS software image you want to use by entering the appropriate b command at the ROM monitor prompt (>):
•
b—Boots the default system software from onboard Flash memory (if it is present in onboard Flash memory)
Caution To prevent system problems, use the b flash command option carefully;
otherwise, you might instruct the system to boot a non-Cisco IOS software image from Flash memory.

Starting the System and Observing Initial Conditions
• •
b flash—Boots the first file in the Flash memory card in PCMCIA slot 0
•
b slot1: filename—Boots the file filename from the Flash memory card in PCMCIA slot 1
•
b filename [host]—Boots the file filename from the server host using TFTP
b slot0: filename—Boots the file filename from the Flash memory card in PCMCIA slot 0
After you boot a Cisco IOS software image, proceed to Step 6. (For additional information on system boot functionality, refer to the section “Manually Booting the System,” later in this chapter.) Step 6
While the system boots from the appropriate Cisco IOS software image, the console screen displays a script and system banner similar to the following: Cisco Internetwork Operating System Software IOS (tm) GS Software (GSR-P-MZ), Released Version 11.2(8)GS Copyright (c) 1986-1997 by cisco Systems, Inc. Compiled Sat 10-May-97 06:02a
Observe the system startup banner. When you start up an unconfigured system for the first time, the system automatically enters the setup facility, which determines which interfaces are installed and prompts you for configuration information for each one. On the console terminal, after the system displays the system banner and hardware configuration, you will see the following System Configuration Dialog prompt: --- System Configuration Dialog --At any point you may enter a question mark '?' for help. Use ctrl-c to abort configuration dialog at any prompt. Default settings are in square brackets '[]'. Continue with configuration dialog? [yes/no]:
You have the option of proceeding with the setup facility or exiting from setup and using configuration commands to configure global (system-wide) and interface-specific parameters. You do not have to configure the interfaces immediately; however, you cannot

Manually Booting the System
enable the interfaces or connect them to any networks until you have configured them. (For configuration information, refer to the section “Configuring the Cisco 12012,” later in this chapter.) The interface-specific LEDs on the line cards might not go on until you have configured the line card interfaces. To verify correct operation of each line card interface, complete the first-time setup procedures and configuration, then refer to the LED descriptions in the configuration notes for each line card to check the status of the interfaces. If the system does not complete each of the preceding steps, proceed to the chapter “Troubleshooting the Installation,” in this publication, for troubleshooting recommendations and procedures.
Manually Booting the System This information in this section is required only if the system does not boot automatically from a specified default Cisco IOS software image. The system is administered using the Cisco command interpreter, called the EXEC. You must boot and log in to the system before you can enter an EXEC command. For security purposes the EXEC has two levels of access to commands: user EXEC mode and privileged EXEC mode. To enter privileged mode, you must enter the enable secret password, which is optional, but must first have been saved in memory. (For information on using passwords, refer to Step 5 and Step 6 in the section “Configuring the Global Parameters,” later in this chapter.) At the ROM monitor prompt, view the contents of onboard Flash memory using the following command: rommon 1> dir bootflash: File size 3277967 bytes (0x32048f) rommon 2>
Checksum 0x6b331e30
File name Cisco 12012 gsr-p-mz.112-8
Also, view the Flash memory PCMCIA card in slot 0 or slot 1 using the following command: rommon 2> dir slot0: File size 3054276 bytes (0x2e9ac4) rommon 3>
Checksum 0x97788495
File name Cisco 12012 gsr-p-mz.112-8
Observing System Startup and Performing a Basic Configuration 4-7
Configuring the Cisco 12012
Locate the Cisco IOS software image that you want to boot and boot from this image using the following commands, as appropriate: rommon 3> boot slot0:filename
or... rommon 3> boot slot1:filename
or... rommon 3> boot bootflash:filename
If you did not change the configuration register setting, the next reload will revert to the default configuration register setting. (The factory default configuration register setting for systems and for RP spares is 0x0102.)
Configuring the Cisco 12012 You can a complete a basic configuration of the Cisco 12012 system using one of the procedures described in the following sections:
•
Performing a Basic Manual Configuration Using the Setup Facility or the setup Command
•
Performing a Basic Configuration Using Configuration Mode
Follow the procedure that best fits the needs of your network configuration. You will need to acquire the correct network addresses from your system administrator or consult your network plan to determine correct addresses before you can complete the router configuration.
Performing a Basic Manual Configuration Using the Setup Facility or the setup Command At initial startup, the Cisco 12012 defaults to the setup facility; the system automatically goes into the setup facility. (The setup command facility functions exactly the same as a completely unconfigured system functions when you first boot it up. You can run the setup facility any time you are at the enable prompt (#) by entering the setup command.) Two parameters of the system configuration are considered during setup: global parameters and interface parameters.

Configuring the Cisco 12012
The primary difference between what you see with the setup facility and what you see with the setup command facility is that with the latter, any current system configuration defaults are displayed in square brackets [ ] as you move through the setup command process and are queried by the system to make changes. For example, during the setup facility for a POS interface, assuming the interface has not been configured, you will see the following: Configuring interface POS4/0: Is this interface in use?: yes Configure IP on this interface?: yes
Note that no default or current conditions are shown in square brackets [ ]. Conversely, you will see the following during the setup command facility, assuming the POS interface has been configured and you are being queried by the system to change it: Configuring interface POS4/0: Is this interface in use?[yes]: yes Configure IP on this interface?[yes]: yes
Note that the default or current conditions of the interface are shown in square brackets [ ]. Proceed to the following section to configure the system using the setup facility or the setup command facility. Differences are clearly noted.
Configuring the Global Parameters When you first start the setup facility or enter the setup command, you are queried by the system to configure the global parameters. The global parameters are used for controlling system-wide settings. Use the following procedure to boot the Cisco 12012 and enter the global parameters: Step 1
Connect a console terminal to the console port on the RP, and then boot the system to the user EXEC prompt (Router>).
Step 2
When you have booted the system, the following information appears after about 30 seconds. (This information is similar to what should appear on your console screen.) When you see this information displayed, you have successfully booted your system:
