About This Document This document is written for administrators and technicians who install devices at the central office (CO). This document should be used in conjunction with the appropriate Hotwire DSL Card User’s Guide or Network Configuration Guide, which describes how to plan the data networks surrounding the DSLAM and specific DSL cards. 1 What is the Hotwire 8810 DSLAM? The Hotwire 8810 Digital Subscriber Line Access Multiplexer (DSLAM), which can be installed at the Network Service Provider (NSP), provides high-speed Internet or intranet access. The 8810 DSLAM is designed to provide a higher port-density carrier, for use with high-density port cards (5 ports or more). Circuit cards with up to four ports access their network Tip and Ring connections using the three connectors located on the front of the unit. The following illustration shows a high-level view of an example Hotwire configuration. Customer Premises (CP) Central Office (CO) Network Service Provider Data Interface Hotwire IPC Ethernet DSL CARD DSLAM MDF CO POTS Splitter SN POTS/DSL POTS CP POTS Splitter Switched Network Voice Interface Optional Optional Legend: DSL – Digital Subscriber Line MDF – Main Distribution Frame SN – Service Node IPC – Interworking Packet Concentrator POTS – Plain Old Telephone Service 99-15674-03 The 8810 DSLAM chassis accepts the following types of cards: H Management Communications Controller (MCC) and MCC Plus cards support both low-density (four ports or fewer) and high-density (5 ports or more) cards. These processor cards administer and provide diagnostic connectivity to the DSL cards. They act as a mid-level manager and work in conjunction with an SNMP network management system, such as HP OpenView, via its LAN port. The MCC/MCC Plus card gathers operational status for each of the DSL cards and responds to the SNMP requests. The card also has a serial port for local terminal access. H MVL, RADSL and DSL cards. These cards provide a processor and an Ethernet interface to the NSP. The processor controls the modems and forwards the packet traffic to and from the Ethernet and DSL interfaces. Models include: — 8310 4-port and 8312 12-port Multiple Virtual Lines (MVL) cards that interoperate with the Hotwire 6310 MVL modem. — 8510 Rate Adaptive Digital Subscriber Line (RADSL) card that interoperates with the 5620 Remote Termination Unit (RTU). 2 — 8540 Digital Subscriber Line (DSL) card that interoperates with either the 5216 or 5246 Remote Termination Unit (RTU). — 8546 DSL card that interoperates with the 5446 RTU. H Multirate High-bit-rate Digital Subscriber Line (M/HDSL) card. H Multirate Symmetric Digital Subscriber Line (M/SDSL) card. NOTE: RADSL, MVL, M/HDSL and M/SDSL cards are generically referred to as DSL cards in this document. The MCC and MCC Plus cards are generically referred to as MCC cards in this document. Hotwire 8810 DSLAM Features The Hotwire 8810 DSLAM chassis has the following features: H Power Redundancy The chassis provides a power input terminal block, which is capable of accepting two independent – 48 Vdc power inputs. Two power sources can be connected to the chassis to provide power redundancy. If one power source fails, the other source provides all of the power needed by the system. This is done automatically without system disruption. The chassis distributes – 48 Vdc power to the individual cards via the interface module and the backplane. H Major/Minor Alarm Contacts for CO Alarm Requirements The interface panel provides two sets of dry contacts on a 6-pin modular jack for connection to a CO alarm system. H LED Indicators for Power and Fan Status and Major and Minor Alarms LEDs on the front panel of the Hotwire 8810 chassis are indicators of the status of chassis functioning (see LEDs on page 31). H Hot Swappable Cards The MCC and DSL cards can be installed and removed from the chassis without service disruption to other cards. H Network Equipment-Building System (NEBS) The 8810 DSLAM is certified to NEBS Level 3. 3 Preinstallation Considerations Consider the following before performing the chassis installation: H Installation Site Your installation site should be well ventilated, clean, and free of environmental extremes. There should be 2 to 3 feet of clearance at the front of the rack in which the chassis is to be installed to allow access for the installation of the chassis, circuit cards, and cables. Also allow for proper clearance at the rear of the rack for cabling. H Power The Hotwire 8810 DSLAM operates from a standard CO – 48 Vdc power supply (– 40.0 to –60.0 Vdc). The power source wires must be either 10 AWG or 12 AWG, and can be either solid or stranded. However, the preferred power source wire is 12 AWG stranded. H Grounding A copper lug connector is attached to the front of the chassis at the bottom right side. It can accept 6 through 14 AWG wire grounding, which meets NEBS requirements. H Card Installation It is recommended that you install DSLAM cards in contiguous slots to optimize the cabling. To eliminate rearranging of port cards and to minimize the cabling required, follow these guidelines when installing DSL cards into the DSLAM: — Cards with up to four ports should be installed in ascending slot order starting with Slot 1. — Cards with more than four ports should be installed in descending slot order starting with Slot 18. For example, if you are installing one 4-port card and one 12-port card, install the 4-port card in Slot 1 and the 12-port card in Slot 18. For expansion, install additional low-density cards in Slots 2 through 6. Install additional high-density cards in starting in Slot 17 down. Make sure that you use the multislot filler plate to cover the empty slots in between. H Cabling Use only CAT3 or better twisted-pair network connection cables for DSL connections and interface patch cabling. Untwisted analog cables of any length anywhere in the loop substantially contribute to crosstalk and reduced loop reach. If there is adequate maintenance space at the rear of the rack, mount the chassis on the rack before installing cables. If there is inadequate space to do this, install the rear-mounted network connectors on the chassis before mounting the chassis on the rack. 4 The following customer-provided cables and cable adapters are required with this product: — Telco 50-pin cable with male connectors for connection to the CO POTS splitter card or MDF. You could need a maximum of up to three of these cables for the front connectors and up to 18 cables for the rear connectors, depending upon the mix of DSL cards installed in your chassis. See Installing Network Tip and Ring Connections on page 21. — 6-pin modular plug cable for connection to a CO alarm system, if required. — 8-pin UTP (Unshielded Twisted Pair) CAT5 modular cable for connection to the DSL 10BaseT Ethernet ports. You will need this cable for each RADSL and MVL card in the DSLAM. For M/HDSL and M/SDSL cards, refer to the appropriate card Installation Instructions for the correct cable needed. — 8-pin UTP CAT5 modular cable for connection to management domain LAN for SNMP management system or Telnet access. — 14-foot serial cable and DB25 and DB9 adapters are required for the MCC card. For connection to a modem, you will need a NULL modem adapter. CAUTION: Use of any nontwisted pair wiring arrangements, such as jumpers, can cause reduction in overall DSL reach performance, even over short distances. NOTE: The Hotwire 8810 DSLAM chassis weighs approximately 30 pounds empty and can be easily installed by one installer. Unpacking the Hardware When shipped, the Hotwire 8810 DSLAM chassis is packed in a cardboard shipping container. Carefully remove the chassis from its shipping container and check for physical damage. If the chassis shows signs of shipping damage, report this immediately to your shipping and sales representatives.

For both the 19- and 23-inch wide rack, the chassis can be installed in one of three depth positions (front flush mount, 3-inch setback, or 5-inch setback). The rack that the chassis will be installed in may or may not have threaded screw holes. Mounting Brackets The chassis is equipped with reversible mounting brackets to allow installation in racks that are either 19 or 23 inches wide. These brackets are initially positioned to allow the chassis to be installed in a 19-inch wide rack. To install the chassis in a 23-inch rack, you must first reverse the mounting brackets as described below. " Procedure 1. Remove the screws that attach the mounting brackets to the sides of the chassis. You may want to use the disassembled mounting brackets as a guide for determining the preferred placement of the chassis in the rack before reinstalling them to the chassis. 2. Taking the bracket from the left side of the chassis, rotate it and place it on the right side so that the longer side extends out. 3. Do the same for the bracket from the right side of the chassis. 4. Replace the screws. 0" 5.0 " 0 0 . 3 19-Inch Rack Installation Flush Mount 0" 5.0 0" 3.0 23-Inch Rack Installation 99-15282a 8 Installation into a 19-Inch or 23-Inch Rack " Procedure To install the chassis in a rack: NOTE: Install the chassis starting at the bottom of the rack. 1. Determine the preferred placement of the chassis in the rack. The chassis is 19.25 inches high. The keyhole slots for a 19-inch rack are located 3.25 inches from the bottom of the chassis. The keyhole slots for a 23-inch rack are located 4 inches from the bottom of the chassis. Mark the appropriate locations for the two lower machine screws on the rack. Use the screwdriver to install the two screws loosely enough to allow the bracket keyholes to drop under the screw heads during installation. 2. Place the chassis against the front rails of the rack allowing the installed machine screws to pass through the keyholes. Lower the chassis into place, allowing the keyholes to slide under the screw heads. This action positions the chassis correctly for installation of the two remaining machine screws and helps support its weight during installation of these screws. 3. Install the two remaining machine screws at the top corners of the chassis and tighten all four. Install the next chassis in the same manner. 9 Installing the Chassis with a 3- or 5-Inch Setback The chassis may be installed with a 3- or 5-inch setback in either the 19- or 23-inch rack. Front Rail Screw Keyhole Front of 19-inch Rack 99-15324a-01 " Procedure 1. Remove the screws that attach the mounting brackets to the sides of the chassis. NOTE: Only two screws are used to attach the bracket on the left side for flush mounting. A third screw, necessary for setback mounting, is already installed behind the left bracket near the top of the chassis. Remove this screw and save it. 2. Position the brackets set back 3 or 5 inches from flush mount. (Refer to procedures for reversing brackets if installing in a 23-inch rack on page 8.) Third Screw for Setback Installation 3. Use three screws on each side to attach the brackets in the setback position. 4. Follow the procedures for installing the chassis in a 19- or 23-inch rack on page 9. 99-15701a 10 Installation into a Rack without Threaded Screw Holes Front Rail Speed Nut Screw Keyhole Front of 19-inch Rack 99-15324b " Procedure To install the chassis in a rack that does not have threaded screw holes: NOTE: Install the chassis starting at the bottom of the rack. 1. Determine the preferred placement of the chassis in the rack. The chassis is 19.25 inches high and the keyhole slots are located 3.25 inches from the bottom of the chassis (for a 19-inch rack). 2. Slip a Speed Nut onto each rail hole selected and align the hole of the Speed Nut with the hole in the rail. 3. Line up the chassis mounting bracket with the Speed Nut and start to rotate the Speed Nut screw into the chassis mounting bracket and the Speed Nut. Start all four screws, then tighten all four until each screw head is flush with the chassis and is securely mounted in the rack. Installing the Optional Air Filter The Hotwire 8810 DSLAM chassis is shipped with an optional air filter. The air filter prevents dust from entering the chassis. Install this air filter when the equipment is to be mounted in a dusty or unfiltered environment. Once it is installed, you should inspect and/or replace the air filter periodically. To purchase a replacement air filter, contact your sales representative. 11 " Procedure To install the optional air filter: 1. Unfasten the screws on the cover plate and remove it. 2.

Replace the cover plate and fasten screws. Supplying Power The Hotwire 8810 DSLAM chassis operates from a – 48 Vdc power source. It allows for two power input feeds which provide input power redundancy. If one power input (e.g., Power A) fails, the system continues to be powered by the other power input (e.g., Power B). The Power A and Power B terminals, which are located on the Interface Panel, are accessible from the front of chassis. Power is distributed from the terminals to the rest of the system. Operation of the LEDs require that the MCC card is installed. See Installing the MCC Card on page 15. CAUTION: It is recommended that the following procedure be performed by a qualified electrician. 12 " Procedure To supply power to the chassis: Make sure that the power source wires are not powered (i.e., the circuit breakers are open or fuses are removed). Verify that the tips of the power source wires (10 AWG or 12 AWG solid or stranded wire) are stripped of insulation. If they are not already stripped of insulation, strip the tip of each wire (about 1/2-inch in length) before plugging each wire into its appropriate terminal on the – 48V input terminal block. Ensure that each wire is fully inserted into the terminal (until it can go no further). If the wire used has thick insulation, you may need to strip more than 1/2 inch to ensure that the wire inserts completely into the terminal. 1. Insert the following wires into the appropriate terminal and fasten each wire by securely tightening the screw above it: Insert the . . . Into the . . . Negative side of the first power source (Power Source A) – 48V (A) input terminal. Positive side of the first power source (Power Source A) RET (A) terminal.

If you are using two power input feeds, ensure that the LEDs associated with both Power Source A and Power Source B are lit. Populating the DSLAM Chassis ! HANDLING PRECAUTIONS FOR STATIC-SENSITIVE DEVICES This product is designed to protect sensitive components from damage due to electrostatic discharge (ESD) during normal operation. When performing installation procedures, however, take proper static control precautions to prevent damage to equipment. If you are not sure of the proper static control precautions, contact your nearest sales or service representative. 496-15149 The MCC card must be installed in Slot 19. DSL cards can be installed in any one of the first 18 slots. However, if you have only one DSL card, it is recommended that you install it in Slot 1. A circuit card may be replaced without disruption to user data (i.e., you can remove and reinstall a card without powering down the 8810 chassis and disrupting user data on the other cards). To remove the card from the base chassis, unfasten the screws on both ends of the faceplate. Then, simply push the ejector handles outward and slide the card out. When swapping a new card for an old card, it is important to note that the 8810 DSLAM retains the Media Access Control (MAC) address, also referred to as the physical address. This means that the new card will have the same MAC address as the old one. Can Accept These Cards . . .
