B-20 1300059 Rev A ix x 1300059 Rev A C hapt er 1 1 I n t ro d u ct i o n This chapter provides an overview of the modified version of the Dual Return Path Receiver (HX6213RXxM). This version of the module uses the same control panel software as the single and quad return path receivers. Section 1.1, Overview—page 1-1 Section 1.2, Warranty— page 1-3 Section 1.3, Related Documents—page 1-4 Section 1.4, Document Conventions— page 1-5 Section 1.5, General Safety Precautions— page 1-5 Section 1.6, Statement of Compliance—page 1-6 1.1 Overview The Dual Return Path Receiver (the module) is among the components available for the Optiworx HWX Transmission System. This module plugs into the HWX Equipment Shelf, along with either one or two Power Supply/Network Controller modules. The equipment shelf can hold up to eight of these modules (single width) as illustrated in Figure 1.1. This flexible, modular design system is based on a 5 RU high, rack- or cabinet-mounted equipment shelf that may be populated in many ways to satisfy a wide range of application needs. The shelf has two dedicated slots for one or two (redundant) Power Supply/Controller modules and eight slots for various transmitter, amplifier, and/or receiver modules. Information on these other components is available in other publications (Section 1.3, Related Documents, on page 1-4). . 1300059 Rev A Introduction 1-1 237 ,1 237 ,1 Figure 1.1 237 ,1 237 ,1 237 ,1 237 ,1 237 ,1 237 ,1 237 ,1 237 ,1 237 ,1 237 ,1 237 ,1 237 ,1 237 ,1 237 ,1 HWX Equipment Shelf Populated with Dual Return Path Receiver Modules In the HWX Transmission Platform, the Dual Return Path Receiver module is intended for installation at the CATV headend or telephony Central Office to receive the return path video, data, and telephony traffic transmitted from the system nodes or other return path transmitters. It provides reverse path reception for both 1310 nm and 1550 nm wavelength transmissions. The module contains two return path receivers, RX1 and RX2. The inputs and outputs of both receivers are independent of each other. Normally, each module operates in dual mode, that is, both receivers are active. However, when only one receiver is needed (in a system with an odd number of channels, for example), RX1 or 2 can be deactivated through software to avoid false alarming. This is referred to as single mode operation. Each return path receiver accepts an intensity-modulated optical input between -2 to -11 dBm for optimum performance, and down to -17 dBm for special applications, from an upstream transmitter. The receivers convert the optical input to an electrical, RF output signal in the reverse or “upstream” band, 5-300 MHz. The level of the output signal is a minimum of +35 dBmV per carrier when the optical input is between -2 and -11 dBm, with 8% OMI. You can attenuate the output level by up to 18 dB from the maximum output level achievable through Control Panel Software or network monitoring software. Power is supplied to the receiver module through the backplane of the equipment shelf by the Power Supply/Controller module, or, in a protected configuration, two Power Supply/Controller modules. The supply voltages come through the equipment shelf backplane, and act as a power source for the module’s internal power supply, which powers the on-board RF amplifiers. The primary Power Supply/Controller monitors the operating parameters for the receivers, interfaces with Network monitoring software, and shows alarm status at the front panel status LED’s on the Dual Return Path Receiver module. 1-2 Introduction 1300059 Rev A 1.2 Warranty C-COR.net shall, at its expense, correct any defect in material and workmanship in products manufactured by C-COR.net which may appear within the warranty period, as set forth herein.

This is why it is important to check and, if necessary, clean optical connectors and adapters before performing any optical connections. Optimum signal transfer between fibers terminated in fiber optic connectors occurs only if fiber ends are mated precisely and there is nothing in between to attenuate, refract, or reflect the lightwave. Fabrication techniques center each fiber and its cladding in the connector cylindrical ferrule. Each ferrule endface is slightly domed (with the fiber at the apex of the dome) and highly polished. The split-sleeve in the bulkhead receptacle, used to mate two connectors, grips the two ferrules snugly and keeps them aligned. Other mechanical features of connectors and adapters hold the ferrule endfaces pressed together. It is the responsibility of the installing technician to ensure that endfaces are clean before they are joined. Figure 2.1 and Figure 2.2 illustrate why a fiberscope is the tool for the job. 2.2 Gathering the Proper Materials Recommended ■ Fiber inspection microscope (“fiberscope”—200X minimum magnification microscope with integral illumination, such as Leica Fibervue 31-22-70 or Noyes Fiber Systems OFS-300, with adapter required to position ferrule of connector type in use) Before proceeding with any of the procedures, obtain the following: ■ Lint free laboratory wipes (Chemtronics Control Wipes or equivalent) ■ Isopropyl alcohol, reagent grade (99.5% pure) ■ Optical Fiber Connector Cleaner (lint-free microporous fabric on an enclosed reel with use-onceand-advance shutter mechanism, Alcoa Fujikura LTD PREP FCC-02-R or equivalent) ® ■ Adapter Cleaner Tips (microporous fabric spiral-wrapped on end of thin plastic handle, Alcoa Fujikura LTD ACT-1 or equivalent) ® 1300059 Rev A Fiber Care and Cleaning 2-1 ! % % $% $ ""# $% "# $% Figure 2.1 ""# $% Fiberscope Inspection of a Fiber Optic Connector Ferrule DANGER: Laser Raditation— When cleaning and performing any fiber optic connections, observe all admonitions indicated in Safety Information on page 4-1 in Chapter 4.

Clean all connectors and adapters before performing optical connections. To Clean a Cable Connector 1. Fold a clean, new wipe into a 2-inch square pad then moisten (not saturate) a 0.5-inch diameter with alcohol. 2. Wrap the moistened part of the pad around the exposed ferrule end and, using firm pressure, twist the pad around the ferrule in at least three back-and-forth, quarter to half-turn rotations. The pad should squeak against the ferrule. 3. Press the ferrule endface into the wet spot on the wipe and, using firm pressure, twist the ferrule so that a wiping action occurs. Repeat twice using a clean alcohol-moistened spot on the pad each time. The pad should squeak against the ferrule. 4. Press the ferrule endface into a dry spot on the wipe and, using gentle pressure, twist the ferrule so that a wiping action occurs. Discard the pad. 5. Inspect the ferrule endface for cleanliness. (We recommend use of a fiberscope for this inspection.) IMAGINARY CIRCLE TWICE THE 125 µm DIAMETER OF THE FIBER CLADDING ENTIRE AREA WITHIN THAT CIRCLE FREE OF ANY CONTAMINATION Figure 2.3 Inspection Standard for Clean Ferrule Endface WARNING: When performing the next step on an angle polished connector, tilt the connector until the angled ferrule endface is parallel with the cleaning tape. Drag the ferrule surface over the tape low side so the sharper high side of the ferrule does not tear the tape fabric. See Figure 2.4. 2-4 Fiber Care and Cleaning 1300059 Rev A 6. If the endface is not clean, or a fiberscope is not available, perform the following: a. Open the access window shutter of the optical fiber connector cleaner reel to expose a new section of cleaning tape then hold the shutter open. b. Using only one side of the exposed tape section, press the ferrule endface firmly against the tape then drag and twist it along the fabric for a sustained wiping action. c. Repeat this along the unused side of the tape section then let the shutter close. Figure 2.4 2.4 Cleaning the Ferrule Endface Cleaning Bulkhead Adapters To Clean a Bulkhead Adapter 1. To clean an empty adapter, pass a fresh adapter cleaner tip through it. Repeat several times. The objective is to remove particles, leaving nothing that can dislodge and fall between the endfaces of connector ferrules. 2. Discard the cleaner tip after using it. 1300059 Rev A Fiber Care and Cleaning 2-5 2 2.5 Cleaning Internal Fiber Optic Connectors Connectors on interior fibers and bulkhead receptacles holding such connectors inside modules are cleaned during factory assembly and then protected by dust covers. Connectors and bulkhead receptacles on modules fresh from the factory should not need cleaning. If modules are left with bulkhead adapters empty and uncapped, contamination may occur. WARNING: Unless a skilled, experienced person performs this procedure, we recommend use of our Repair Services. If returning a module for such service is not a viable option, you may use the procedure below. If you, the customer, perform these steps, you do so at your own risk. Repair of damages caused by performance of these steps will be at your expense. To Clean Internal Fiber Optic Connectors 1. Remove the module from the equipment shelf. 2. Position the module with the front panel in an upright position as in Figur e2.5. 3. Remove the two mounting screws. (Hold the module so that the optical input bulkhead receptacle will not fall away from the front panel after the two mounting screws have been removed.) Mounting Screw Mounting Screw Figure 2.5 Removing the Bulkhead Receptacle Mounting Screws 4. While holding the bulkhead receptacle to the front panel, place the module on its side on a flat surface as in Figure 2.6. This allows the internal fiber optic cable loop to rest on the module cover. This minimizes the risk of it snagging circuit board components as the bulkhead receptacle is extended away from the module. 5. Slowly withdraw the bulkhead receptacle from the module, being careful not to snag the fiber optic cable on any internal module components. Extend the bulkhead receptacle enough to allow space to remove the cable from the rear of the bulkhead receptacle. Do not exceed 2 inches (Figure 2.6). 2-6 Fiber Care and Cleaning 1300059 Rev A Fiber Optic Cable 2 2’’ Figure 2.6 Ma x. Flat Surfa ce Removing the Optical Input Connector If you cannot extend the optical input bulkhead receptacle far enough for access: a. Replace and secure the bulkhead receptacle to the front panel. b. Place a protective cap over the fiber optic input cable. c. Return the module to C-COR.net for cleaning. For information on returning the module, contact C-COR.net Technical Support. 6. Disconnect the suspect fiber optic connector from the rear of the optical input bulkhead receptacle. 7. To clean the connector and bulkhead receptacle, refer to Cleaning Cable Connectors on page 2–4 and Cleaning Bulkhead Adapters on page 2–5. Do not over extend the cable during cleaning. 8. When cleaning is completed, reconnect the fiber optic connector to the rear of the bulkhead receptacle: To Connect an FC Connector to a Bulkhead Receptacle a. Keeping the connector ferrule in line with the bulkhead receptacle split-sleeve, insert the connector into the split-sleeve. b. Rotate the connector until its key slips into the keyway then thread the connector cap until fingertight. Figure 2.7 1300059 Rev A Connector/Bulkhead Receptacle Connection Fiber Care and Cleaning 2-7 To Connect an SC Connector to a Bulkhead Receptacle c. Orient the connector to align its keyed side with the slotted-keyway side of the bulkhead receptacle split-sleeve. d. Keeping the connector ferrule in line with the split-sleeve, insert the connector into the split-sleeve until the mating latches click. 9. Slowly slide the cable into the module, taking care not to snag the fiber optic cable. 10. Holding the bulkhead receptacle to the front panel, place the module in an upright position. Secure the bulkhead receptacle to the front panel reusing the original screws. 2-8 Fiber Care and Cleaning 1300059 Rev A Chapter 3 Ph ys ica l De scr ip ti o n 3 This chapter provides an overview of the modified version of the Dual Return Path Receiver (HX6213RXxM). This version of the module uses the same control panel software as the single and quad return path receivers. Section 3.1, Physical Identification—page 3-1 Section 3.2, Functional Description—page 3-3 Section 3.3, Redundancy—page 3-6 3.1 Physical Identification The Dual Return Path Receiver module is a plug-in module designed exclusively for the HWX Transmission Platform. The module measures 1.7”W x 6.8”H x 10.1”D and weighs approximately 4.5 pounds. The circuitry is completely enclosed in a metal housing. The Dual Return Path Receiver is designed to operate at temperatures from 0°C to +50°C with non-condensing relative humidity of 10 to 90%. Up to eight modules can be installed in a single shelf. Note: The module can be installed in an HWX Equipment Shelf having an HWX Power Supply/Controller. Exceptions are earlier model shelves (HX1281ES) and controllers (HX2481PC) that are not equipped to support these modules. A Quick Reference Guide (Figure 3.1) is provided to for location of each of the HX6213RX module’s controls, LED indicators, and connectors. Table 3.1, Front Panel Indicators, Controls, and Connection Points, on page 3-3 also provides information on all of the front panel items. 1300059 Rev A Physical Description 3-1 Thumb-screw for securing module to HWX shelf RF Output 1 Connector RF OUTPUT MON/1 Test Point -20 dB ALARM 1 LED Green = OK Red = Alarm RF Output 2 Connector ON LINE LED Green = On Line Out = Off Line ALARM 2 LED Green = OK Red = Alarm Equipment shelf Connector RF OUTPUT MON/2 Test Point -20 dB A/B Module Switch ENABLE/DISABLE (Requires external combiners) Optical Input Connectors OPT IN 1 OPT IN 2 IPD 2 Receiver 2 optical input Test Point and GND Figure 3.1 3-2 Physical Description IPD 1 Receiver 1 optical input Test Point and GND Quick Reference Guide 1300059 Rev A Table 3.1 Front Panel Indicators, Controls, and Connection Points TYPE LABEL FUNCTION F Connector RF OUTPUT MON/1 RF OUTPUT MON/2 75-ohm connection points for monitoring each output RF signal.

FC or SC OPT IN 1 OPT IN 2 Optical input connector options: SC/APC, FC/APC, SC/UPC or FC/UPC. Test Points IPD 1 IPD 2 Accesses a voltage derived from the photodiode current. The voltage relates to the optical input at the rate of 50 mV/dB, and 1 V represents a 0 dBm (1 mW) optical input level. (For example, an IPD test point reading of 800 mV indicates an optical input level of -4 dBm (0.4 mW). Note 1: Refer to Appendix A, HX6213RX Firmware Factory Settings. On the rear panel of the module are two (2) F-type connectors and a DIN style edge connector (48 pin socket) which are both mounted on the module’s printed circuit board. The F-type connectors provide the receiver RF outputs, and the edge connector mates with the equipment shelf’s internal motherboard connectors. 3.2 Functional Description The HX6213RXM (Figure 3.2) receivers accept intensity-modulated optical inputs within the RF return path frequency range of 5 to 300 MHz. RF output levels and performances are determined by the optical input levels to the receiver and the optical modulation index (OMI) produced by the carriers at the return transmitter: ■ -11 to -8 dBm is the optical input range for optimum performance over the full range of return transmitter OMI’s. ■ -11 to -2 dBm is the optical input range for optimum performance with OMI/channel levels of less than 11%, and may require use of the internal RF attenuator to reduce RF output to less than +56 dBmV. ■ -17 to -11 dBm is an acceptable optical input range, but may yield reduced performance depending on transmitter OMI/channel levels. 1300059 Rev A Physical Description 3-3 3 A RECEIVER OUTPUT 5-300 MHz 35 dBmV/ch-16ch 14 dB -12 dB Equalizer/Pad -7 dB 14 dB VVA -3 t0 -21 dB 14 dB Photodiode OPT IN 1 14 dB Receiver Output Level Adjust Pad Microprocessor IPD Monitor Receiver A Bias Receiver Monitor Output -20 dB A/B V ref Decoder & DC Power V ref Switch A/B Control DC Power to RF Amps B RECEIVER OUTPUT 5-300 MHz 35 dBmV/ch-16ch 14 dB -12 dB Equalizer/Pad -7 dB 14 dB VVA -3 t0 -21 dB 14 dB Photodiode OPT IN 2 14 dB Receiver Output Level Adjust Pad Receiver Monitor Output -20 dB Figure 3.2 Bias IPD Monitor Receiver B Functional Block Diagram The HWX Dual Return Path Receiver Module contains two functional return path receivers as illustrated in Figure 3.2. The module accepts two optical inputs (OPT IN 1 and OPT IN 2) from return path (upstream) transmitters. These optical signals each drive a photodiode to produce an electrical RF signal that is amplified and equalized to produce a minimum +35 dBmV/channel output with an input of -11 dBm and 8% OMI for up to 16 channels from each receiver. The photodetector is coupled to a preamplifier whose output is then fed to a variable (0 – 18 dB) attenuator (VVA). The second stage of amplification is fed to an equalizer that will compensate for the expected 300 MHz, 0.5 dB roll-off for each of the four amplifier stages. Following the equalizer is another amplifier that drives the final push-pull output amplifier. The push-pull arrangement provides the extra dynamic range and balanced conditions necessary for good CSO performance. The RF output levels are dependent on the optical input power level and OMI index. Input levels between -2 and -11 dBm are guaranteed to result in a minimum of +35 dBmV/channel output level with an 8% OMI. Within this range, input levels closer to -2 dBm will result in higher output levels; input levels closer to -11 dBm will result in lower output levels. An in-range input will always produce an output that can be 3-4 Physical Description 1300059 Rev A attenuated to +35 dBmV. Input levels between -11 and -17 dBm result in progressively lower output power levels, and poorer performance. Refer to Figure 3.3 and Figure 3.4 for typical RF outputs vs. optical input power and Optical Modulation Index (OMI) levels. WARNING: The module is capable of operation over a wide range of optical input levels and optical modulation indexes. Some ISX return path transmitters operate at a high OMI. The combination of high optical input level and high OMI may damage the module RF output amplifiers. The modules are shipped with the internal variable attenuator set to maximum attenuation to protect for this condition until optical input signals can be measured and optimized. RF Output levels above +56 dBmV/Channel are considered high. Figure 3.3 indicates typical RF Output values based on optical input levels and associated OMI indexes. The values assume that the internal RF Attenuator is set at 0 dB. Anything in the red (dark) zone requires use of the internal attenuator to reduce the optical input power level. Figure 3.3 Typical RF Output Values Based on Optical Input Levels and OMI Indexes Figure 3.4 is a graph of RF Output based on optical input levels and associated OMI indexes with the modules internal RF Attenuator set at -18 dB to limit the output level. Figure 3.4 1300059 Rev A RF Output Values based on Optical Input Levels and OMI Indexes (Internal RF attenuator set to maximum) Physical Description 3-5 3 At any output power level, the signal can be attenuated by up to 18 dB. The internal variable attenuator is controlled by software. The receiver Control Panel software displays a setting that corresponds to the attenuation applied to each receiver. The user adjustment is accessed using the receiver control panel software (refer to the Output Level Setting on page B-15 in Chapter B for details). If the application requires connection to an external combiner, all inputs to the combiner should be at the same level. If the optical input level is greater than -8 dBm, it may require that an external in-line attenuator be placed on the RF output port of the receiver, prior to the combiner, or the transmitter OMI lowered. 3.3 Redundancy There are two modes of operation: Independent and Redundant. In the Independent mode, if a receiver(s) in a module fails, there is no switching to a backup receiver or module. Redundancy allows switching. A/B PAIR A/B PAIR A/B PAIR 1 2 3 4 A B A B P1 P2 A/B PAIR 5 6 7 8 B A B A PS/C PS/C HWX Equipment Shelf Figure 3.5 HWX Equipment Shelf Paired Primary and Secondary Equipment Slots Primary (A) or secondary (B) status is determined by a module’s position in an HWX equipment shelf. The equipment slots in the shelf are defined as either A or B by backplane wiring. On the left side of the shelf, the leftmost slot of each pair of equipment slots holds the primary module. On the right side of the shelf, the rightmost slot of each pair holds the primary module, refer to Figure 3.5. The A/B switch, which is set in the side of the module, lets you select either Redundant or Independent operation. The switch has two positions: ENABLE and DISABLE. If the switch is placed in the ENABLE (leftmost) position, redundant operation for that module is made available. If the switch is placed in the DISABLE (rightmost) position, the module is configured for Independent operation. For a graphic illustration of the location of the A/B switch, refer to Figure 3.1 on page 3-2. 3-6 Physical Description 1300059 Rev A One requirement for Redundancy is that the A/B switches of both module in a pair be in the ENABLE position. Any other combination results in an Independent mode of operation between the pairs. Table 3.2 indicates the mode of operation as a function of the module’s A/B switch position. Table 3.2 1. 2. A/B Switch Position and Mode of Operation MODULE A MODULE B MODE OF OPERATION Enable Enable Redundant1 Enable Disable Independent2 Disable Enable Independent Disable Disable Independent 3 A/B Switch position is only one requirement of Redundancy. For a further explanation on the requirements of Redundancy, refer to Selecting Redundancy on page B-20 in Chapter B. For Internal redundancy mode of operation, the primary Module A will remain in the Internal mode. 1300059 Rev A Physical Description 3-7 Modes of Redundancy There are three modes of Redundancy: Internal, Module, or Channel. 3.3.1 Internal In this mode a module’s receivers are paired. Primary and secondary refers to the receivers within the same module, not between modules. Receiver 1 and 2 are a pair (Receiver 1 is the primary and Receiver 2 is the secondary. Refer to Figure 3.6, "Before". 1 2 RF OUTPUTS 5; Active Inactive 5; A or B OPTICAL INPUTS 2 1 Before Figure 3.6 After Internal Switching If RX1 develops a major alarm condition, switchover to RX2 within the same module will occur provided that RX2 does not have any major alarm condition, Figure 3.6, "After". Note: If the secondary receiver is DISABLED (example RX2) or its Major Low level threshold set of “OFF”, the primary receiver (example RX1) exceeds its Major Low level threshold setting, internal switchover will not occur. 3-8 Physical Description 1300059 Rev A 3.3.2 Module In this mode, if the optical input to any one of the primary module (A slot) receivers (1 or 2) falls below the Major low limit, the device will switch both receivers to the secondary module (B slot). 3 RF OUTPUTS 5; 5; 5; Active Active 5; 2 1 RF OUTPUTS Inactive Inactive Inactive Active Active 5; 5; 2 1 RF OUTPUTS 5; 5; 2 1 RF OUTPUTS Inactive 2 1 A B A B OPTICAL INPUTS 2 1 OPTICAL INPUTS 2 1 OPTICAL INPUTS 2 1 OPTICAL INPUTS 2 1 Before Figure 3.7 After Module Switching Figure 3.7, "Before" shows a pair of HX6213RX modules in normal operation with all inputs to both modules within alarm threshold settings. Both receivers in primary module (A) will be active and both the receivers in the secondary module (B) will be inactive. Any input, to either primary receiver, that exceeds its major low alarm threshold settings (in this example RX1) will cause both the primary receivers to go inactive and both the secondary receivers to become active (Figure 3.7, "After"). Note: If a receiver in the secondary (B) module is DISABLED (example RX1) or its Major Low level threshold set of “OFF”, and the corresponding receiver in the primary (A) module (example RX1) exceeds its Major Low level threshold setting, module switchover will not occur. However, if the failure in the primary (A) receiver is not the same receiver (in this example RX2 in module B), module switchover will take place. 1300059 Rev A Physical Description 3-9 3.3.3 Channel In this mode, if an optical input to one of the primary module (A) receivers (1or 2) falls below the Major low limit, only that receiver will be switched to the secondary module (B), and the other receiver will remain active in the primary module.

Figure 3.8, "After", is an example where the input to receiver RX2 of the primary (A) module fell outside of its threshold limits. The module will automatically switch receiver RX2 in the primary (A) module to inactive, and activate receiver RX2 in the secondary (B) module. Note: If a receiver in the secondary (B) module is DISABLED (example RX2) or its Major Low level threshold set of “OFF”, and the corresponding receiver in the primary (A) module (example RX2) exceeds its Major Low level threshold setting, channel switchover will not occur. 3-10 Physical Description 1300059 Rev A Chapter 4 In st al la ti o n an d In it i al Tes t This chapter provides procedures for unpacking, installation of the HX6213RX in the HWX Equipment Shelf, and initial turn-up and test.

DANGER: Laser Radiation— To avoid exposure to invisible laser radiation, do not look into the ends of any optical fiber connectors or bulkhead adapters. Use an optical power meter to identify active fibers. Do not assume that laser power is turned off or that a fiber is disconnected at its far end. DANGER: Laser Radiation— Infrared radiation is invisible and can seriously damage the retina of the eye. To avoid potentially dangerous radiation exposure, immediately place a protective cap or hood over any radiating bulkhead receptacle or optical fiber connector. This practice also keeps dirt particles from entering the connector. WARNING: To prevent electrical shock, never install electrical equipment in a wet location or during a lightning storm. CAUTION: HWX equipment is electrostatic discharge sensitive. To prevent electrostatic discharge damage, wear a grounded wrist strap when you touch HWX equipment. Always place units on an approved, grounded antistatic surface. Use antistatic packaging when transporting equipment. 1300059 Rev A Installation and Initial Test 4-1 4.2 Unpack Equipment Open the shipping cartons and verify that all parts have been received and that no shipping damage has occurred. Before proceeding, obtain the following tools and equipment: ■ ESD wrist strap ■ ESD antistatic mat ■ Box cutter Note: Retain the shipping carton and shipping material in case you need to return the equipment at a later date. To Unpack and Inspect the Module 1. Place the ESD wrist-strap on your wrist and snap the ground wire to the wrist-strap connection. Plug the ground plug into a grounded ESD jack. 2. Examine the shipping carton exterior for tears, dents, etc., that might indicate shipping damage. If found, contact C-COR.net Technical Support for instructions. 3. Open the carton then carefully unpack the equipment. 4. Check each component against the packing list to ensure that the correct catalog numbers and quantities were received. Note any discrepancies. 5. Inspect each item for damage. Check for detached, broken or bent parts, and any other physical damage to the module. Do not install a product that is significantly damaged. 6. If there is damage to the equipment, contact C-COR.net Technical Support for further instructions. 4-2 Installation and Initial Test 1300059 Rev A 4.3 Install the Module Before proceeding, read the following if you are using or are planning on using the Redundancy mode. 4.3.1 A Discussion of the Redundant Mode of Operation Slot A is the primary receiver module and slot B is the secondary receiver module. If the optical input to the primary module (A) receiver falls below the MajLo threshold setting and the secondary module (B) receiver input is within limits, the module will switch from the primary module receiver to the secondary module receiver. One requirement for Redundancy is that both A/B switches of module pairs are in the ENABLE (up) position. Any other combination results in an Independent mode of operation between the pairs. Table 4.1 indicates the mode of operation available as a function of the A/B switch setting in a module pair. Table 4.1 A/B Switch Position and Mode of Operation Module A Module B Mode of Operation Enable Enable Redundant1 Enable Disable Independent Disable Enable Independent Disable Disable Independent 1. A/B Switch position is only one requirement of Redundancy. For a further explanation on the requirements of Redundancy, refer to Section 3.3, Redundancy, on page 3-6. Before proceeding, obtain the following: ■ ESD wrist-strap ■ Modules to be installed ■ Small bladed screwdriver ■ Torque wrench (20 inch-pounds setting) for RF cable installation ■ Protective caps or plugs as needed to cover every fiber optic connector and bulkhead optical receptacle to be dealt with at the HWX shelf location ■ HX1281BM blank module cover (use HX1281BP for a Power Supply/Controller slot) for any HWX shelf slot not occupied by a module, to ensure proper heat dissipation and minimize EMI WARNING: When using the following procedure, observe all admonitions indicated in Section 4.1, Safety Information, on page 4-1. Note: The module can be installed in an HWX Equipment Shelf having an HWX Power Supply/Controller. Exceptions are earlier model shelves (HX1281ES) and controllers (HX2481PC) that are not equipped to support these modules. 1300059 Rev A Installation and Initial Test 4-3 4 4.3.2 To Install the Module 1. Place the ESD wrist-strap on your wrist and snap the ground wire to the wrist-strap connection. Insert the ground plug into a grounded ESD jack. 2. Modules are shipped with A/B switches in DISABLE (down position). If installing a Redundant pair, use a small-bladed screwdriver to set the A/B switch to ENABLE (up position) for both modules in the pair. A/B switch position is only one requirement for Redundancy. For further information, see Section 4.7, Redundancy Switching Verification, on page 4-15. CAUTION: A module can be removed or installed when the shelf is powered up (hot swapped) without risk of system damage or interruption. Do not use excessive force when inserting a module into the equipment shelf. Excessive force, e.g., slamming the module into shelf, can cause system interruption. 3. Slide the module into the slot. If installing modules for use in the Redundant mode, see the Note below. The 48-pin DIN connector at the rear of the module will mate with the equipment shelf backplane when the module is fully inserted (top of module front panel rests against the top shelf rail). Note: With respect to Redundant mode pairs, on the left side of the shelf, the left-most slot of each pair (A) holds the primary module. On the right side, the right-most slot of each pair (A) holds the primary module. Refer to Figure 4.1 A/B PAIR A/B PAIR 1 2 3 4 A B A B A/B PAIR P1 P2 PS/C PS/C A/B PAIR 5 6 7 8 B A B A HWX Equipment Shelf Figure 4.1 Redundant Mode Pair Slot Positioning 4. If the equipment shelf is not powered up, proceed to step 5.1 Otherwise, upon module insertion, the ALARM and ON LINE LED’s should momentarily light and then return to a steady-state status. If not: a. Gently reinstall the module ensuring that the 48-pin connector mates with the shelf backplane. b. If the LED’s do not momentarily light, contact C -COR.net Technical Support for direction. 5. Press the spring-loaded captive retaining screw at the top front panel then turn it clockwise to engage the threads. Finger-tighten the retaining screw. 6. Repeat step 2 through step 5 for each module that you are installing. 1. If the equipment shelf is not powered up at this time, do not be concerned. You will perform the same LED test that you would have performed in this step when you proceed to the Initial Functional Check after finishing this procedure. 4-4 Installation and Initial Test 1300059 Rev A 7. Cover unused Power Supply/Controller slots with blank panel assembly HX1281BP and unused module/transmitter/amplifier slots with blank module assembly HX1281BM. Insert the tab at the bottom of the assembly into the slot in the floor of the shelf module compartment then secure the panel with its spring-loaded captive retaining screw. 8. Identify the input fiber optic cable that is to be attached to the module(s). 9. Ensure that the cable is routed through the opening at the lower rear of the shelf, across the fiber management tray, and out the front of the shelf. 10. Contamination of an optical interface can severely degrade the performance of a fiber optic system. We recommend that you clean all optical connectors before performing any optical connections. For instructions, refer to Chapter 2, Fiber Care and Cleaning. WARNING: A high optical input level may damage the internal drive amplifiers of the module. Therefore, it is necessary to check the optical input levels before performing any optical connections. 4 11. Once cleaning is completed, check the optical input level of each optic cable to ensure that the level is within proper limits. Perform Section 4.4, Checking Optical Input Levels, on page 4-7 before proceeding to the next step. 12. After all input fiber optic cables have had the input levels verified, connect the input fiber optic cable to the optical input bulkhead receptacle (Figure 4.2) on the module. ■ For FC type connector, proceed to the next step. ■ For SC type connector, go to Step 14. Optical Input Bulkhead Receptacles Figure 4.2 Optical Input Bulkhead Receptacle 13. To Connect an FC Connector to a Bulkhead Receptacle: a. Keep the connector ferrule in line with the bulkhead receptacle split-sleeve (Figure 4.3), insert the connector into the split-sleeve. b. Rotate the connector until its key slips into the keyway then thread the connector cap until fingertight. Proceed to Step 15. 1300059 Rev A Installation and Initial Test 4-5 Figure 4.3 Connector/Bulkhead Receptacle Connection 14. To Connect an SC Connector to a Bulkhead Receptacle: a. Orient the connector to align its keyed side with the slotted-keyway side of the bulkhead receptacle split-sleeve. b. Keeping the connector ferrule in line with the split-sleeve, insert the connector into the split-sleeve until the mating latches click. Proceed to the next step. 15. Dress the fiber optic input cable where it turns up to connect to the bulkhead connector so as to prevent the cable from kinking. 16. Leave a 6-inch diameter strain-relief loop in the cable then secure the cable in one of the anchor clips on the optical organizer tray. Note: With respect to the next step, if using the module in the Redundant mode, you must combine the RF output of both modules in the pair via an external coupler before connecting the combined RF output to the network. 17. On the rear of the module, connect the network RF output coaxial cable to the RF OUTPUT connector, passing the cable through the cutout provided in the rear of the equipment shelf. CAUTION: We recommend use of a torque wrench to attach the RF output cable to the module. Do not exceed 20 inch-pounds. Excessive force can damage the RF connector. 18. Finger tighten the RF cable then torque to 20 inch-pounds (1/8 turn, if no torque wrench is available). 4-6 Installation and Initial Test 1300059 Rev A 4.4 Checking Optical Input Levels It is necessary to check the optical input to the module to assure optimal performance and to ensure that the input does not exceed acceptable limits. High optical inputs can damage the module’s receiver circuitry. WARNING: The module is shipped with internal attenutation (Output Level Setting field) set high. Leave the attenuation set high. This will mitigate a high optical input level and help protect the receiver’s amplifier circuitry. High optical input and OMI levels can cause receiver RF output to exceed 70 dBmV. This level can damage the receiver RF amplifier circuitry. 1. Use Control Panel Software to check the Receiver Output Level setting and Optical Input. For information on initiating a Control Panel Software session, refer to Appendix B.4, Initiating a Control Panel Software Session, on page B-18. Once initiated, the Dual Receiver Control Panel appears. 4 2. In the Dual Receiver Control Panel, select the desired module Slot. 3. If this is an initial installation or an unknown optical input level, ■ First verify or set RX1 and RX2 receiver Output Level Setting to 600 (maximum attenuation), then ■ Using an optical power meter (or spectrum analyzer) measure the incoming fiber optic cable signal level for both receivers (RX1 and RX2). 4. If the incoming fiber optic cable is already connected, ■ Measurements can be taken at the IPD test points located on the front panel of the receiver (use Table 4.2 below for VDC to mW conversion) or by monitoring the Receiver Optical Input field in the control panel software dialog box. Table 4.2 Optical Input dBm µW -2 630 -3 1300059 Rev A Optical Input (dBm) vs IPD (Voltage) IPD Voltage µVDC Optical Input IPD Voltage µVDC dBm µW 900 -10 100 500 500 850 -11 80 450 -4 400 800 -12 63 400 -5 316 750 -13 50 350 -6 250 700 -14 40 300 -7 200 650 -15 32 250 -8 160 600 -16 25 200 -9 125 550 -17 20 150 Installation and Initial Test 4-7 5. If the level is: ■ above -8 dBm (160 µW), reduce the input power level to between -8 to -17 dBm. Either install an in-line attenuator or reduce the input power from the return path transmitter (refer to the documentation that accompanied the transmitter). Recheck Receiver Optical Input to ensure proper input level. ■ between -11 dBm (80 µW) and -8 dBm (160 µW), the level is acceptable. ■ between -17 dBm (20 µW) and -11 dBm (80 µW), the level is acceptable but performance will be reduced. ■ below -17 dBm (20 µW), clean and inspect the input fiber optic cable. Recheck the input signal level. If greater than -17 dBm, repeat step 5. If still below -17 dBm, the input power from the reverse path transmitter must be increased (refer to the documentation that accompanied the transmitter). When complete, recheck Receiver Optical Input to ensure proper input level. 6. Return to the procedure step that brought you here. 4-8 Installation and Initial Test 1300059 Rev A 4.5 Initial Functional Check This procedure covers initial power-up, and interpretation and response to initial front panel LED indications using front panel controls. It assumes that the: ■ A/B Switch is properly positioned. ■ Equipment shelf is powered up. ■ Equipment shelf and Power Supply/Controller module(s) are operational. WARNING: When using the following procedure, observe all admonitions indicated in Section 4.1, Safety Information, on page 4-1. 4 CAUTION: There are no field serviceable components in the module. Failure to comply can result in voiding of the warranty. Before proceeding, obtain the following: ■ ESD wrist-strap ■ Protective caps or plugs, as needed, to cover every fiber optic connector and bulkhead optical receptacle to be dealt with at the equipment shelf location 4.5.1 Verify Installation 1. Place the ESD wrist-strap on your wrist and snap the ground wire to the wrist-strap. Insert the ground plug into a grounded ESD jack. 2. Check all modules in the shelf to ensure that optical input receptacles have fiber optic cables properly connected. If not, connect the cables using Steps 8 through 16 in Section 4.3.2, To Install the Module, on page 4-4. 3. Verify that no alarm conditions exist on previously installed modules in the shelf (module ALARM LED’s should be green). a. If an alarm condition exists, unseat then gently reinsert the module with the alarm condition. b. If the condition is still present, refer to the documentation that accompanied the module for fault isolation procedures, then continue to the next step after corrective action is completed. 4. If not already performed (LED Test), unseat then gently reinsert the Quad Return Path Receiver ensuring that the 48-pin DIN connector on the rear of the module mates with the shelf backplane receptacle. Observe that the ALARM and ONLINE LED’s momentarily light and then return to a steady-state green condition. If the LED’s do not momentarily light, repeat this step a second time. If repetition does not provide the desired results, contact C-COR.net Technical Support for direction. 5. Disable any receivers (RX1–4) that will not have a fiber optic cable connection. This will preclude having a major alarm when power is applied to the module. Refer to Section B.3.9, Receiver Enable/ Disable, on page B-16, for details. 6. Ensure that the Power Supply/Controller has the latest firmware. To determine the version of firmware, refer to Appendix B.2.4.1, Verifying Firmware Revision Level, on page B-6. If an upgrade is needed, continue to install per procedure. 1300059 Rev A Installation and Initial Test 4-9 7.

For information on factory-set thresholds, refer to Appendix A, HX6213RX Firmware Factory Settings. 1300059 Rev A Installation and Initial Test 4-11 4 4.6 Checking RF Output Signal Levels WARNING: When using the following procedure, observe all admonitions indicated in Section 4.1, Safety Information, on page 4-1. Use this procedure for checking and adjusting the RF output of both module receivers (Rx1 & Rx2). Before proceeding, obtain the following: ■ ESD wrist-strap ■ Spectrum analyzer or RF level meter ■ Torque wrench (20 inch-pounds setting) RF Output Signals If less than 16 channels are being carried, the output levels will be correspondingly higher. Refer to Table 4.3. Table 4.3 Number of Channels vs. Output Level/Carrier Using ISXRPTXA Return Transmitter % OMI No. of Channels Output Level/Carrier 8 16 35 dBmV 11 8 38 dBmV 16 4 41 dBmV 23 2 44 dBmV 32 1 47 dBmV If the application requires connection to an external combiner, all inputs to the combiner should be at the same level. If the optical input level is greater than -8 dBm, it may require that an external in-line attenuator be placed on the RF output port of the receiver, prior to the combiner, or the transmitter OMI lowered. To Measure and Adjust the RF Output Signal Level 1. Place the ESD wrist-strap on your wrist and snap the ground wire to the wrist-strap connection. Plug the ground plug into a grounded ESD jack. 2. The RF output signal of a receiver (RX1 or RX2) can be measured at the RF OUTPUT MON/1 or 2 connectors on the front panel (–20 dB with respect to the actual output level), or directly at the RF Output connectors at the rear of the module. Select the method most appropriate to your circumstances. To Measure the RF Output Level at a RF OUTPUT MONITOR Connector (front panel) a. Connect a test lead from a spectrum analyzer or RF level meter to the RF OUTPUT MON/1 or 2 connector on the front panel of the module to obtain a reading. b. Measurements at the RF OUTPUT MON are sampled at a level below the actual signal level at the RF Output connector on the rear of the module. To obtain the actual level, add 20 dB to the measured level. Proceed to Step 3. 4-12 Installation and Initial Test 1300059 Rev A To Measure the RF Output Level at the RF Output Connector (rear panel) c. Disconnect the RF output cable from an RF Output connector on the rear of the module. d. Connect a test lead from a spectrum analyzer or RF level meter to the RF Output. 3. Verify that the output level is within specification and meets system design needs. Refer to Chapter 6, Specifications for output level specifications. ■ If the output level is within specification, go to step 6. ■ If the output level is not within specification, initiate a control panel session. For information on initiating a Control Panel Software session, refer to Initiating a Control Panel Software Session on page B-18. Once initiated, the Dual Receiver Control Panel appears. 4. In the Dual Receiver Control Panel, select the desired module slot. 4 5. While monitoring the output level on the test equipment, enter a new attenuation value in the Output Level Setting (550 - 4095) field then press Enter on the keyboard. The range permitted is 550 to 4095. This corresponds to 20 to 0 dB of attenuation, respectively. For a comparison of the Output Level Setting value and the actual attenuation in dB, refer to Figure 4.4 on page 4-14. 6. Repeat the previous steps for the other receiver. 7. When finished, disconnect the test equipment: ■ If connected to the RF MONITOR connector, disconnect the test lead from the test equipment. ■ If connected to the RF Output connector, disconnect the test lead and reconnect the RF output cable. Finger-tighten the cable then torque it to 20 inch-pounds (1/8 turn, if no torque wrench is available). WARNING: We recommend that you use a torque wrench to reattach the RF out cable to the RF Output connector. Do not exceed 20 inch-pounds of torque. Excessive force can damage the RF connector. 8. If the outputs are (or were adjusted to) within specification, the module is operational. – or – If the RF output signal level is not within specification and cannot be adjusted to such, contact C-COR.net Technical Support for direction. 1300059 Rev A Installation and Initial Test 4-13 24 Actual Signal Attenuation (dB) 22 20 18 16 14 12 10 8 6 4 2 9 63 9 67 72 4 3 78 9 85 3 95 78 10 43 12 48 14 63 15 78 16 03 18 22 82 40 89 0 Control Panel Software Attenuation Setting Figure 4.4 4-14 Attenuation Versus Control Panel Software Attenuation Setting Installation and Initial Test 1300059 Rev A 4.7 Redundancy Switching Verification This procedure verifies that proper switching between the primary and secondary receivers/modules occurs if major alarm thresholds are exceeded.

Section 5.1, Safety Information—page 5-1 Section 5.2, Troubleshooting the Independent Mode of Operation—page 5-2 Section 5.3, Troubleshooting the Redundant Mode of Operation—page 5-4 5 5.1 Safety Information The following safety information is pertinent to the installation procedures, and should be read prior to turn-up, testing, and troubleshooting of the module. DANGER: Laser Radiation— To avoid exposure to invisible laser radiation, do not look into the ends of any optical fiber connectors or bulkhead adapters. Use an optical power meter to identify active fibers. Do not assume that laser power is turned off or that a fiber is disconnected at its far end. DANGER: Laser Radiation— Infrared radiation is invisible and can seriously damage the retina of the eye. To avoid potentially dangerous radiation exposure, immediately place a protective cap or hood over any radiating bulkhead receptacle or optical fiber connector. This practice also keeps dirt particles from entering the connector. WARNING: To prevent electrical shock, never install electrical equipment in a wet location or during a lightning storm. CAUTION: HWX equipment is electrostatic discharge sensitive. To prevent electrostatic discharge damage, wear a grounded wrist strap when you touch HWX equipment. Always place units on an approved, grounded antistatic surface. Use antistatic packaging when transporting equipment. 1300059 Rev A Troubleshooting Test Procedure 5-1 5.2 Troubleshooting the Independent Mode of Operation The following pages are a guide to the nature of alarm conditions in modules operating in the Independent mode.

The RX1 and RX2 indicators appear green if enabled and red if disabled. In cases where you want only one receiver in a module activated, you would disable the appropriate receiver to prevent false alarming. Note: Redundancy requires that a module pair have RX1 and RX2 enabled as appropriate. For further information, see Selecting Redundancy on page B-20. B.3.10 Receiver Optical Input This field indicates the optical input signal level to the module receivers. The range is typically –11 to –2 dBm. B.3.11 RF Output On/Off This indicator shows if the module receivers are active (green) or inactive (red). B.3.12 Save This button lets you store changes that you make to an alarm threshold field(s). If you enter new values but decide not to save your input, you can use Cancel to restore the most recently stored information. B-16 Dual Receiver Control Panel Software 1300059 Rev A B.3.13 Slot Slot radio buttons are representative of module slot positions in the HWX equipment shelf. Slot positions determine the primary (P) and secondary (S) locations for module pairs and are so indicated. On startup, the software automatically selects the first slot that contains a single, modified dual, or quad receiver. ■ ■ ■ A white radio button indicates a slot that contains a receiver module, but is not selected. A white radio button with a black dot in the center indicates that the receiver slot is selected. A gray radio button indicates that a slot is either empty or does not contain a single, modified dual or quad return path receiver module. To Select a Module to Monitor In the Dual Receiver Control Panel, click the white radio button in the Slot field for the receiver module that you want to monitor. B.3.14 Tool Tips When the cursor is placed over a control or field, a message (Figure B–17) appears describing the function of that control or field. B Figure B–17 Tool Tip 1300059 Rev A Dual Receiver Control Panel Software B-17 B.4 Initiating a Control Panel Software Session Before proceeding, ensure that there is a DB-9 cable connection between the PC COM port and the Computer Port connector on the active Power Supply/Controller module (blinking, green POWER LED). To Initiate a Session Use quadrx.exe file for single, dual modified or quad receiver applications. 1. From the Windows Explorer, open the folder containing Control Panel Software then double-click quadrx.exe, – or – Double-click the Quadrx.exe icon on your Desktop. Figure B–18 The Quadrx.exe File The Dual Receiver Control Panel dialog box (Figure B–19) appears indicating that it is establishing connection to the Power Supply/Controller. If the RS-232 cable is not connected, or the Power Supply/Controller is off, an error message appears. If so: a. Click OK then verify that there is proper connection of the DB-9 cable between the COM port on the computer and the Computer Port connector on the active Power Supply/Controller. b. Ensure that the Power Supply/Controller is operational (blinking green POWER LED) then repeat this procedure from step 1. B-18 Dual Receiver Control Panel Software 1300059 Rev A 2. Module detection occurs automatically. From this dialog box you can: ■ Select a module to monitor. ■ Monitor the optical input signal level to each module receiver. ■ Set the RF output level of each module receiver. ■ Monitor and set the optical input alarm thresholds of each module receiver. ■ Display the manufacturing information related to the module. ■ Download new firmware to the module. ■ Monitor and select the switching mode for redundant pairs. B Figure B–19 The Dual Receiver Control Panel Dialog Box (Example) 1300059 Rev A Dual Receiver Control Panel Software B-19 B.5 Selecting Redundancy There are a few conditions that must be met before a module pair can exhibit Redundancy: ■ ■ ■ ■ Both modules must have their A/B switches set to ENABLE. Note that modules are shipped with their A/B switch in DISABLE. For the location of the A/B Switch, see Figure 3.1 on page 3-2. Both modules must be enabled through software, i.e., the Receiver Enable/Disable option in the Dual Receiver Control Panel must be set to Enable for both modules. For further information, see Receiver Enable/Disable on page B-16. The modules must be inserted in slots as adjacent pairs. See Table B.1. Can only select redundancy mode from the primary (A) module. Table B.1 Redundancy and Slot Positions Primary Slot (A) Secondary Slot (B) 1 2 3 4 6 5 8 7 If the above conditions are not met, the module pairs will operate in the Independent mode. If there is a pair setup to operate in the Redundancy mode and one of the modules is removed from the shelf, the other will automatically switch to the Independent mode. When the module is reinstalled, the pair will automatically resume operation in the Redundancy mode (provided that the above bulleted conditions are met). The only exception to the above is if the secondary module is removed and the primary module is set to Internal Redundancy, the primary module will remain in the Internal Redundancy mode of operation. For Module or Channel redundancy, if the input signal level to a module is within threshold limits (Optical Alarm Status indicator green), the primary module is activated (RF Output On/Off indicator green) and the secondary module is inactivated (RF Output On/Off indicator red), the primary and secondary module dialog boxes will appear as in Figure B–20 and Figure B–21.
