24 Rack Mounting. Rack Mounting. The G10 CMTS chassis must be rack mounted prior to the installation of any additional power supplies or modules. Never power on the G10 CMTS without first grounding the chassis. 1. The G10 CMTS accessory kit contains a two-ring lug connector that must be crimped to the earth ground strap. 2. Using the two supplied #10 hex bolts, attach the two-ring lug connector of the ground strap to the chassis using 20 in lb of torque on each bolt. Figure 3 on page 4 shows the location of the chassis ground nuts on the chassis. 3. Ensure that proper clearance is maintained between the G10 CMTS chassis and its surroundings to allow adequate air ventilation to flow into the air intakes and out of the air exhaust: A minimum of 3 feet (0.91 m) between the front of the chassis and any other object A minimum of 2 feet (0.61 m) between the rear of the chassis and any other object A minimum of 3 inches between each side of the chassis and any other object The G10 CMTS does not require any clearance between the bottom of the chassis and the floor. Similarly, there are no clearance requirements between the top of the chassis and the bottom of another G10 CMTS stacked above it on the same rack. 4. It is recommended that an equipment shelf be installed into the rack that can support the maximum weight (140 lb, or 64 kg) and dimensions of the chassis. The chassis dimensions, when viewed from the bottom, are provided in Figure Juniper Networks G10 CMTS Getting Started

25 Rack Mounting. Figure 6: Bottom of Chassis 17.3 in (439.4 mm) Front 5. If the chassis will be front-rack mounted, proceed to Step 7. If the chassis will be mid-rack mounted, proceed to Step Remove the seven screws fastening the mounting brackets to the front of the chassis, align the brackets with the corresponding hole patterns in the center of the chassis, and insert the seven screws into the chassis. Apply 20 in lb of torque to each of the seven screws. 7. Using at least three installers, slowly lift and slide the G10 CMTS onto the equipment shelf until the flanges of the mounting brackets are flush with the mounting rails of the rack, and the mounting holes in the mounting brackets are aligned with the corresponding holes in the mounting rails. 8. Using the twelve #12 screws supplied in the accessory kit (six for each mounting bracket), fasten the chassis to the rack by applying 30 in lb of torque to each of the 12 screws. 9. Attach the ground strap to earth ground. At this point, the installation of any additional power supplies or modules can be installed in the chassis as described in Installing Supplies on page 14 through Installing a Rear-Loaded Module on page in (472.6 mm) Do not use the handles on the rear fan tray to assist with lifting the G10 CMTS. These handles are solely for the purpose of removing the rear fan tray. G10 CMTS Installation 13

26 Installing Supplies 14 Installing Supplies Juniper Networks G10 CMTS Getting Started Before installing a power supply or any module into the G10 CMTS, attach one end of an ESD ground strap to your wrist and attach the other end to the ESD strap jack on the front of the chassis (refer to Figure 2 on page 3). 1. The power supply faceplate must be removed by pulling the flanges on each side of the faceplate away from the chassis until the faceplate ball studs are removed from the power supply faceplate clips. 2. Decide the bay in which the power supply will be inserted. As described in the Juniper Networks G10 CMTS Functional Description, the midplane is partitioned into two domains Domain A (slots 1 6) and Domain B (slots 7, 9 13). The AC power supplies in each domain are supplied from the power source connected to that domain s AC power transition module. However, the DC outputs of all ten power supplies in both domains are interconnected along the midplane. Therefore, if power source redundancy is not a consideration, adding an AC power supply to either domain will supply additional power to all of the modules in the chassis. However, if power source redundancy is desired, the addition of an AC power supply in one domain must be accompanied with the addition of an AC power supply in the other domain. Within a domain, a power supply can be installed in any of the available five bays. Figure 7 on page 16 illustrates the two power supply domains. Unlike the AC configuration, the DC power transition modules do not operate independently. Each DC power transition module supports the power supplies in both domains of the chassis. Therefore, power supply redundancy is independent of the domain in which a power supply is installed. 3. Remove the power supply filler panel covering the selected bay by loosening the two self-contained screws. 4. If the power supply s ejector is locked in the vertical position, press down on the ejector release while simultaneously pulling the ejector away from the power supply. The ejector should rest at approximately 45 from the faceplate. The power supplies and the chassis are mechanically keyed to ensure that same-type supplies and chassis (AC or DC) are used together. Do not attempt to remove or reconfigure the keys. 5. Align the printed circuit board of the power supply with the bay card guides and slowly slide the power supply into the bay until it comes to a stop with the inside tabs of the ejector (tabs closest to midplane) resting over the power supply ejector rail (refer to Figure 8 on page 17). 6. Firmly lift the ejector to the vertical position until the ejector release clicks into position. 7. Tighten the upper and lower retainer screws by applying 3 in lb of torque to each screw.

27 G10 CMTS Installation Installing Supplies Replace the power supply faceplate by aligning its four ball studs with the four power supply faceplate clips and pressing the faceplate towards the chassis until it snaps into place. The power supply faceplate must be replaced prior to powering on the G10 CMTS to ensure that proper air ventilation occurs throughout the chassis.

29 Installing a Front-Loaded Module Figure 8: Supply Installation Installing a Front-Loaded Module 1 This section describes the procedure for installing a DOCSIS Module, a Chassis Control Module, and a NIC Module. Refer to Figure 7 on page 16 and Figure 5 on page 6 for views of the front, rear, and top of the chassis midplane. DOCSIS Modules are installed in front card cage slots 1 through 4 (for Domain A) and slots 10 through 13 (for Domain B). Chassis Control Modules are installed in front card cage slot 6 (for Domain A) and slot 7 (for Domain B). NIC Modules are installed in front card cage slot 5 (for Domain A) and slot 9 (for Domain B). NIC Modules are shipped from the factory with two Multi-Mode GBIC modules installed. If you are using a different GBIC module interface, you will need to replace the Multi-Mode GBIC modules that are shipped with the NIC Module. GBIC module removal and installation is performed while the NIC Module is installed in the chassis. Fault Do not install DOCSIS Modules that support the DOCSIS standard and DOCSIS Modules that support the EuroDOCSIS standard within the same G10 CMTS chassis. DOCSIS Modules that support EuroDOCSIS are labeled as such on the front panel of the module. 2 G10 CMTS Installation 17

30 Installing a Front-Loaded Module 18 Table 1: Supply Guideline Juniper Networks G10 CMTS Getting Started As DOCSIS Modules are installed in your CMTS, ensure the correct number of power supplies are installed to support your configuration. The Juniper Networks production guideline for the number of power supplies to install for N+1 power supply redundancy is provided in Table 1. To implement full power redundancy (power supplies, power transition modules, and input power), the number of power supplies installed in domain A must also be installed in domain B. Number of DOCSIS Modules Number of Supplies 1. If an air management panel is installed in the slot to be populated, remove it from the card cage. 2. Unlock the ejectors of the module to be installed so that each ejector rests at approximately 45 away from its locked position. 3. Align the printed circuit board of the module with the card guides and slowly slide the module into the slot until it comes to a stop with the inside tabs (tabs closest to midplane) of the upper and lower ejectors resting directly under and over, respectively, the module ejector rail (refer to Figure 9 on page 19). 4. Simultaneously close the ejectors toward the module faceplate to the vertical position until each ejector release clicks into position. 5. Tighten the two retainer screws by applying 3 in lb of torque to each screw. 6. If you have installed a NIC Module and you will be using a GBIC module interface other than Multi-Mode, then you must replace the Multi-Mode GBIC modules that are shipped with the NIC Module. Remove each Multi-Mode GBIC module from the installed NIC Module by squeezing the metal clasps at the top and bottom of the GBIC module towards the module itself, and firmly pull out the module until it is fully removed from its slot. 7. The GBIC modules that you will be using must now be installed in the NIC Module. With the label side of the GBIC module facing the right, slide each module into its NIC Module slot until the metal clasps at the top and bottom of the module click into place. The GBIC module can only be installed one way. If it is oriented in its slot incorrectly, it will stop about halfway into the slot. If this occurs, remove the GBIC module, rotate it 180, and reinstall it.

31 Installing a Rear-Loaded Module Figure 9: Front-Loaded Module Installation Installing a Rear-Loaded Module This section describes the procedure for installing an HFC Connector Module, a CCM Access Module, and a NIC Access Module. Refer to Figure 7 on page 16 and Figure 5 on page 6 for views of the front, rear, and top of the chassis midplane. HFC Connector Modules are installed in rear card cage slots 1 through 4 (for domain A) and slots 10 through 13 (for domain B). CCM Access Modules are installed in rear card cage slot 6 (for Domain A) and slot 7 (for Domain B). NIC Access Modules are installed in rear card cage slot 5 (for Domain A) and slot 9 (for Domain B). 1. If an air management panel is installed in the slot to be populated, remove it from the card cage. G10 CMTS Installation 19

32 Installing a Rear-Loaded Module 20 Figure 10: Rear-Loaded Module Installation Juniper Networks G10 CMTS Getting Started 2. Unlock the ejectors of the module to be installed so that each ejector rests at approximately 45 away from its locked position. Unlike front-loading modules, the ejectors on rear-loading modules lock in the horizontal position (90 from the faceplate) when the module is properly installed into its card slot. 3. Align the printed circuit board of the module with the card guides and slowly slide the module into the slot until it comes to a stop with the inside tabs (tabs closest to midplane) of the upper and lower ejectors resting directly under and over, respectively, the module ejector rail (refer to Figure 10 on page 20). 4. Simultaneously close the ejectors toward the module faceplate to the horizontal position until each ejector release clicks into position. 5. Tighten the two retainer screws by applying 3 in lb of torque to each screw. 1 US 0 US 1 US 2 US 3 Eth0 Eth1 DS 0 DS 1 DS 2 DS 3 2 2

33 Cabling an HFC Connector Module Cabling an HFC Connector Module Each DOCSIS Module and its corresponding HFC Connector Module support a total of four downstream channels, where one channel is assigned to each physical downstream port. Each DOCSIS Module supports a total of 8 or 16 upstream channels (depending on the DOCSIS Module model) which can be logically allocated to any one of the four physical upstream ports. Figure 11 on page 21 illustrates an example where the number of channels allocated on each port is five, three, seven, and one, respectively. The assignment of a node to a port, and the allocation of upstream channels per upstream port should be considered prior to connecting the coaxial cables from the cable plant to the HFC Connector Module. Figure 11: Example of Allocation of Multiple Channels Per Port Prior to inserting a coaxial cable into any of the HFC Connector Module F-connectors, ensure that the cable meets the requirements provided in the Juniper Networks G10 CMTS Installation and Configuration manual. One possible deployment scenario for the upstream is to attach one node per upstream port and to turn on one upstream channel per node. If one of the nodes reaches capacity due to high penetration or heavy usage of bandwidth-intensive services, then another channel can be provisioned on that port. In the following procedures, a node may represent a single node, or multiple nodes that are combined. G10 CMTS Installation 21

35 Cabling a Chassis Control Module Cabling a Chassis Control Module When connecting nodes to the upstream ports of an HFC Connector Module, do not split a coaxial cable from one node and attach it to more than one upstream port. Doing so prevents using the complete features of a DOCSIS Module that were designed for supporting four separate nodes or four groups of nodes that are combined. The following procedure describes how to connect to the downstream ports (refer to Figure 12 on page 22 for port labeling): 1. Select the first node(s) in the cable plant for assignment to the first of four downstream ports. Connect the coaxial cable associated with the first node(s) to the F-connector on the HFC Connector Module labeled DS If applicable, repeat the previous step for the second, third, and fourth nodes for connection to downstream ports DS 1, DS 2, and DS 3, respectively. The following procedure describes how to connect to the upstream ports: 3. Select the first node(s) in the cable plant for assignment to the first of four upstream ports. Connect the coaxial cable associated with the first node(s) to the F-connector on the HFC Connector Module labeled US If applicable, repeat the previous step for the second, third, and fourth nodes for connection to upstream ports US 1, US 2, and US 3, respectively. If a NIC Module in not used in the G10 CMTS, connect each of the two 10/100BASE-T Ethernet RJ-45 ports labeled Eth0 and Eth1 to the appropriate network equipment in the headend (refer to Figure 12 on page 22 for port labeling). The Chassis Control Module contains a 10/100BASE-T Ethernet RJ-45 port labeled Eth0 on its front panel (refer to Figure 13 on page 24). This port is used for the management interface to the G10 CMTS. The following procedure describes how to connect this port to the network: 1. Carefully thread the Ethernet cable into the cable channel from the rear of the chassis (refer to Figure 3 on page 4) until it extends through the opening of the power supply faceplate. 2. Plug the RJ-45 connector of the Ethernet cable into the RJ-45 port of the Chassis Control Module labeled Eth0. 3. Attached the other end of the Ethernet cable to its respective network equipment in the headend. The CCM Access Module is not used in this procedure. G10 CMTS Installation 23

37 Cabling a NIC Module Cabling a NIC Module The NIC Module contains two full-duplex, 1-Gigabit Ethernet GBIC (Gigabit Interface Converter) transceiver ports on its front panel. Refer to the Juniper Networks G10 CMTS Installation and Configuration manual for the specifications of the various types of GBIC interfaces provided. The following procedure describes how to connect the network cables to these ports (refer to Figure 14 on page 26 for port labeling): 1. Carefully thread each of the two cables into the cable channel from the rear of the chassis (refer to Figure 3 on page 4) until they extend through the opening of the power supply faceplate. 2. Connect the transmit/receive pair of each of these cables to the GBIC ports labeled 0 and 1 on the NIC Module. 3. Attached the other end of each cable to its respective network equipment in the headend. If using optical cables, take care not to bend the cables too sharply when threading them through the cable channel. 4. Repeat this process if another NIC Module is installed in the chassis. Figure 15 on page 27 provides the front view of the chassis with the network cables installed into a NIC Module. Both ports on each NIC Module must be connected to the network if redundancy is desired. G10 CMTS Installation 25

40 Cabling a NIC Access Module 28 Cabling a NIC Access Module Juniper Networks G10 CMTS Getting Started This section describes how to interconnect up to two NIC Access Modules to multiple HFC Connector Modules in a non-redundant configuration. The procedure assumes that a NIC Module only supports the DOCSIS Modules installed in the same domain of the chassis. Therefore, if five or more DOCSIS Modules are installed in the system, then two NIC Modules are installed to support them. In addition, the procedure assumes that DOCSIS Modules are installed in the following slot order: 1, 2, 3, 4, 10, 11, 12, 13. In this particular procedure, the RJ-45 ports of the CCM Access Module labeled Eth0 and Eth1 are unused. The NIC Access Module cables are used to interconnect the Fast Ethernet ports of the HFC Connector Modules to the NIC Access Module. The 12 RJ-45 connectors on the NIC Access Module cable plugged into the connector labeled 2 on the NIC Access Module can be used as general purpose switched FastEthernet ports. Refer to Table 1 on page 18 for details. It is recommended that the following procedure be followed to allow for future wiring considerations. 1. If applicable, remove the protective cover that is inserted into the RJ-21 end of the NIC Access Module cable. 2. Firmly insert the RJ-21 end of the cable into the connector labeled 1 on the NIC Access Module in slot 5 (refer to Figure 14 on page 26). 3. Tighten the two cable retainer screws by applying 4 in lb of torque to each of the screws. 4. Locate the RJ-45 connectors of the NIC Access Module cable labeled PORT 5 and PORT 6 and plug them into the RJ-45 ports of the HFC Connector Module in slot 1 labeled Eth0 and Eth1, respectively (refer to Figure 12 on page 22 for port labeling). If an HFC Connector Module is installed in slot 2, proceed to Step 5; otherwise, jump ahead to Step Locate the RJ-45 connectors of the NIC Access Module cable labeled PORT 7 and PORT 8 and plug them into the RJ-45 ports of the HFC Connector Module in slot 2 labeled Eth0 and Eth1, respectively. If an HFC Connector Module is installed in slot 3, proceed to Step 6; otherwise, jump ahead to Step Locate the RJ-45 connectors of the NIC Access Module cable labeled PORT 9 and PORT 10 and plug them into the RJ-45 ports of the HFC Connector Module in slot 3 labeled Eth0 and Eth1, respectively. If an HFC Connector Module is installed in slot 4, proceed to Step 7; otherwise, jump ahead to Step Locate the RJ-45 connectors of the NIC Access Module cable labeled PORT 11 and PORT 12 and plug them into the RJ-45 ports of the HFC Connector Module in slot 4 labeled Eth0 and Eth1, respectively. If an HFC Connector Module is installed in slot 10, proceed to Step 8; otherwise, jump ahead to Step 15.

41 Cabling a NIC Access Module 8. If you have reached this step in the procedure, then at least five HFC Connector Modules are installed in the G10 CMTS, in which case a second NIC Access Module and its corresponding cable are required to complete the interconnection procedure. If applicable, remove the protective cover that is inserted into the RJ-21 end of the NIC Access Module cable. 9. Firmly insert the RJ-21 end of the second NIC Access Module cable into the connector labeled 1 on the NIC Access Module in slot 9 (refer to Figure 14 on page 26). 10. Tighten the two cable retainer screws by applying 4 in lb of torque to each of the screws. 11. Locate the RJ-45 connectors of the NIC Access Module cable labeled PORT 5 and PORT 6 and plug them into the RJ-45 ports of the HFC Connector Module in slot 10 labeled Eth0 and Eth1, respectively. If an HFC Connector Module is installed in slot 11, proceed to Step 12; otherwise, jump ahead to Step Locate the RJ-45 connectors of the second NIC Access Module cable labeled PORT 7 and PORT 8 and plug them into the RJ-45 ports of the HFC Connector Module in slot 11 labeled Eth0 and Eth1, respectively. If an HFC Connector Module is installed in slot 12, proceed to Step 13; otherwise, jump ahead to Step Locate the RJ-45 connectors of the NIC Access Module cable labeled PORT 9 and PORT 10 and plug them into the RJ-45 ports of the HFC Connector Module in slot 12 labeled Eth0 and Eth1, respectively. If an HFC Connector Module is installed in slot 13, proceed to Step 14; otherwise, jump ahead to Step Locate the RJ-45 connectors of the NIC Access Module cable labeled PORT 11 and PORT 12 and plug them into the RJ-45 ports of the HFC Connector Module in slot 13 labeled Eth0 and Eth1, respectively. 15. At this point, all of the Ethernet ports of the HFC Connector Modules should be connected to the NIC Access Module. Figure 16 on page 30 provides an illustration of these connections (without the HFC Connector Module coaxial cables shown). 16. All used and unused Ethernet cable wires on either NIC Access Module cable should be dressed appropriately and routed to avoid obstructing the rear connections of the G10 CMTS. Table 2 on page 31 summarizes the NIC Access Module wiring plan used in this procedure. The Module Slot / Port headings specify the module name, the slot in which the module is installed, and the RJ-45 port label of the module. G10 CMTS Installation 29

Ports 1 12 on Cable 2 correspond to FastEthernet ports 0 11, respectively, under the interface fastethernet sub-mode for the NIC Module. Initial configuration of the G10 CMTS requires a direct connection between a personal computer (PC) and the Chassis Control Module. Using the DB-9 to DB-9 null modem serial cable supplied in the accessory kit, connect one end of the cable to the RS-232 DB-9 port labeled COM on the Chassis Control Module front panel (refer to Figure 13 on page 24), and connect the other end to the serial port on your PC. An adapter may be needed to connect the DB-9 connector of the cable to the serial port of your PC (for example, DB-9 to DB-25). G10 CMTS Installation 31

44 Connecting to Sources 32 Connecting to Sources AC Juniper Networks G10 CMTS Getting Started Ensure that you have read and taken the proper safety precautions as described in the Juniper Networks G10 CMTS Installation and Configuration manual prior to connecting any power source to the G10 CMTS. Each AC power transition module in the G10 CMTS chassis contains a standard IEC 15-A three-prong male AC power receptacle for connecting to an AC power source (refer to Figure 3 on page 4). Facing the rear of the chassis, the AC power transition modules on the right and left sides of the chassis independently support the power supplies in Domain A and Domain B, respectively. To enhance the redundancy capabilities, each power transition module must be powered by sources on different circuits. The following procedure describes the steps for connecting the AC power transition modules to their power sources (refer to Figure 17 on page 33): 1. Ensure that the rocker switch on each AC power transition module is in the OFF (O) position. 2. Swing the power cord retainer clips to their upright position, plug the female end of each 15-A power cord supplied with your shipment into the AC power receptacle on each AC power transition module, then close the retainer clips so that they clasp around the power cords. 3. Plug the male end of each 15-A power cord to independent power sources. Always use AC power sources that support the ground prong of the power cord. The G10 CMTS power supplies are autosensing which enables them for usage with 110 VAC or 220 VAC.

45 Connecting to Sources Figure 17: AC Cord and Retainer Clip DC Each DC power transition module in the G10 CMTS chassis contains a terminal block for connecting to a DC power source (refer to Figure 18 on page 34). Unlike the AC configuration, the DC power transition modules do not operate independently. Each DC power transition module supports the power supplies in both domains of the chassis. To enhance the redundancy capabilities, it is recommended that each power transition module be powered by sources on different circuits. Cord Retainer Clip The following procedure describes the steps for connecting the DC power transition modules to their power sources: 1. Shipped with the G10 CMTS are ring lugs that are used to connect the DC power cord to the DC power transition module terminal block. These ring lugs must be crimped to the negative ( ) and positive (+) wires of the DC power cord in order to properly connect to the DC power transition module. 2. Remove the screw from the negative ( ) terminal on the terminal block of the DC power transition module, insert the screw through the ring lug of the power cord that will be attached to the negative ( ) terminal of the DC power source, and tighten the screw into the negative ( ) terminal on the terminal block. Apply 20 in lb of torque to the screw. 3. Remove the screw from the positive (+) terminal on the terminal block of the DC power transition module, insert the screw through the ring lug of the power cord that will be attached to the positive (+) terminal of the DC power source, and tighten the screw into the positive (+) terminal on the terminal block. Apply 20 in lb of torque to the screw. G10 CMTS Installation 33

46 Connecting to Sources Juniper Networks G10 CMTS Getting Started Connect the other end of the power cord connected to the negative ( ) terminal on the terminal block of the DC power transition module to the negative ( ) terminal of the DC power source in accordance with the manufacturer s specifications. 5. Connect the other end of the power cord connected to the positive (+) terminal on the terminal block of the DC power transition module to the positive (+) terminal of the DC power source in accordance with the manufacturer s specifications.

47 Chapter 3 G10 CMTS Configuration ing On the G10 CMTS This chapter describes the configuration procedure for the G10 CMTS. It is assumed that the installation procedures described in G10 CMTS Installation on page 9 have been followed prior to performing the procedures presented in this chapter. It is recommended that the entire configuration process in this chapter be read prior to performing the actual G10 CMTS configuration. The following steps define the power-on procedure and the expected state of the LEDs on the power supplies, fan trays, and module panels that should be monitored after the G10 CMTS is powered on. If the G10 CMTS does not power up correctly, refer to the Juniper Networks G10 CMTS Installation and Configuration manual for the possible causes and corresponding actions to take. 1. Ensure that the power sources connected to the power transition modules are on. 2. If the G10 CMTS is AC-powered, press the rocker switch on each AC power transition module to the ON ( ) position. There is no requirement that the two power switches be turned on in any particular order. If the G10 CMTS is DC-powered, the system will be powered up when the DC power transition modules have been connected to the DC power sources. 3. Remove the power supply faceplate by pulling the flanges on each side of the faceplate away from the chassis until the faceplate ball studs are removed from the power supply faceplate clips.ensure that all power supplies are operating normally by checking that the POWER LED is illuminated green and the FAULT LED is not illuminated. 4. Replace the power supply faceplate by aligning its four ball studs with the four power supply faceplate clips and pressing the faceplate towards the chassis until it snaps into place. 5. Ensure that the fan tray LEDs (two in front, one in rear) are not illuminated (refer to Figure 1 on page 2 and Figure 3 on page 4 for the location of these LEDs). To minimize the risk of damage to the G10 CMTS, a failed fan tray should be replaced as soon as possible to ensure that proper air ventilation occurs throughout the chassis. G10 CMTS Configuration 35
