Install the Chassis
To install the chassis in the rack, follow this procedure:
Tip (Optional) Install an equipment shelf in the rack to support the Cisco uBR10012 router chassis. This simplifies installation and provides additional support for the chassis. If you are installing an equipment shelf, it must be able to support the weight of a fully loaded chassis, which is approximately 230 lbs (104.3 kg).
Caution Two people are required to lift this chassis. Three people might be needed to position the chassis into a rack, depending on whether you are using an equipment shelf and on how high you are mounting it.
If you have to lift the chassis to a higher location, have a third person present who can lift the middle of the chassis as the other two people lift it straight up.
Step 1 With a person standing on either side of the chassis, grab one of the handles on the side of the chassis and use the other to steady the chassis.
Step 2 Carefully lift the chassis straight up and carry the it to the rack.
Step 3 When you reach your destination, lower the chassis to the ground.
Tip To prevent injury, keep your back straight and lift with your legs, not your back.
Step 4 Taking hold of the chassis, lift the chassis up to the height that it will be positioned in the rack.
Note The chassis is usually installed in the bottom of the rack.
Step 5 Maneuver the chassis into position in the rack.
Step 6 Align the mounting bracket holes with the rack post holes and attach the chassis to the rack with the appropriate-sized screws (performed by the third person, unless the chassis is resting on the bottom of the rack or a shelf).
Note Figure 11 shows the chassis flush-mounted at the rear. The procedure is identical for the other mounting methods.
Figure 11 Installing the Chassis in a Rack

a. Connect one lead to the common (COM) terminal.
b. If you are wiring the router in with other equipment for the alarm indicators, connect the other lead to the normally closed (NC) terminal.
c. If you are wiring the router in parallel with other equipment for the alarm indicators, connect the other lead to the normally open (NO) terminal.
Note Figure 14 shows the wiring configuration for NO alarm relays. For NC alarm relays, use the NC contacts.
Step 4 Repeat Step 3 for the remaining alarm indicators
Step 5 Secure the alarm and power cabling to the chassis:
a. Feed a tie wrap through the square slot on the left front side of the chassis (next to the alarm indicator terminal block).
b. Bind the wires to the chassis using the tie wrap.

Replacing the Modules
PRE Modules
Step 1 Align the PRE module with the card guides in the slot. See Figure 15.
Step 2 Slide the card into the slot until you can feel it seat in the backplane connectors.
Step 3 Close the ejector levers to secure the card in the backplane, and tighten the captive screws to secure the card in the chassis.
Figure 15 Installing the PRE Module
DC Power Entry Modules
Step 1 Verify that the power switch is in the OFF position.
Step 2 Position the first DC PEM in the power bay and push it forward, verifying that it goes all the way in and makes a secure connection with the backplane. See Figure 16.
Step 3 Tighten the captive screws to secure the DC PEM.
Step 4 Repeat these steps to install the second DC PEM.
Caution Make sure that the alarm cables and the DC cables are out of the way before you slide the PEMs into the power bay.
Figure 16 Installing a DC PEM
AC Power Entry Modules
Do not use the DC terminal blocks when you are using the AC PEMs. Verify that the DC terminal blocks are not connected to any wires before proceeding with the installation. AC PEMs are rated for 200-240 VAC at 13 A.
Step 1 Verify that the power switch on the AC PEM is in the OFF position.
Step 2 Position the AC PEM in the power bay and push it forward, verifying that it goes all the way in and makes a secure connection with the backplane.
Step 3 Use a screwdriver to tighten the captive screws.
Step 4 Plug the AC-input power cable into the power receptacle on the front of the AC PEM.
Step 5 Route the power cable up the front of the AC PEM and clip it into the two plastic retaining clips. The power cables go out through the notch on the right side of the front cover when it is installed.
Step 6 Plug the other end of the AC-input power cable into a 200-240 VAC power outlet. The FAULT LED on the AC PEM is yellow, indicating that the AC PEM is receiving power from the power source, but is not yet supplying power to the Cisco uBR10012 chassis. Do not turn on the power yet.
Tip For fully redundant operation, each AC PEM should use separate power sources. Alternately, you can use an uninterruptable power supply (UPS).
Figure 17 AC PEM Standby Position
Fan Assembly Module
Step 1 Using two hands, pick up the fan assembly module.
Caution The fan assembly module weighs approximately 30 lbs (13.61 kg)
Step 2 Align the module with the rails in the chassis. See Figure 18.
Step 3 Push the fan module back firmly into the chassis, making sure that the module securely connects to the backplane.
Step 4 Tighten the captive screws on each side of the fan assembly module.
Figure 18 Replacing the Fan Assembly
Line Cards and Uplink Cards
Caution The Cisco uBR10-LCP2-MC16 or -MC28 cable interface line card must be installed as one unit. Do not install the card adapter carrier (Cisco uBR10-LCP2) without the line card. Cisco uBR-MC5x20 cards are used in the example. Always check the captive screws that secure the line card to the adapter card (card carrier) before installation.
Step 1 Align the upper and lower edges of the card with the upper and lower guides in the chassis. See Figure 19.
Tip Grasp the faceplate of the card with one hand and place your other hand under the card carrier to support the weight of the card. The cards can weigh up to 16+ lbs.
Step 2 Slide the card into the slot until you can feel it seat in the backplane connectors.
Step 3 Close the ejector levers to secure the card in the backplane, and tighten the captive screws to secure the card in the chassis.
Caution To ensure that there is adequate space for additional cable interface line cards, always tighten the captive screws on each newly installed card before you insert any additional cards. The captive screws prevent accidental removal and provide proper grounding for electromagnetic interference (EMI) shielding.
Step 4 Repeat Step 1 through Step 3 for each cable interface line card and network uplink line card.
Figure 19 Replacing the Line Cards and Uplink Cards
Replacing the HHGE Line Cards
Caution Always install the HHGE line cards in a slot splitter. Slot splitters must be installed in slot 3 or slot 4 of the chassis. If you have a blank slot, always install a blank slot cover. Use half-height slot covers when you have a single open HHGE slot. Use full-height slot covers in all other situations.
Step 1 Grasp the faceplate of the line card with one hand and place your other hand under the card carrier (to support the weight of the card). Position the card in front of the slot splitter.
Step 2 Carefully align the upper and lower edges of the line card with the upper and lower guides in the slot splitter, and slide the line card about half-way into the splitter.
Step 3 Be sure the ejectors are in the open position and continue to push the line card into the splitter until you can feel it begin to seat in the backplane connectors.
Step 4 Verify that the captive screws are properly aligned with the captive screw holes in the splitter. If the captive screws are not properly aligned, the card will not seat properly in the backplane.
Step 5 Simultaneously pivot both ejector levers toward each other (until they are parallel to the faceplate) to firmly seat the card in the backplane.
The HHGE line card cycles through its power-on self-test. The FAIL LED lights during portions of the POST (Power-On Self Test), but remains off after POST on a properly working line card. If the FAIL LED remains on, go to the "Troubleshooting" section.
5 Connecting Cables
Tip To reduce the chance of interference, avoid crossing the power cables with any of the interface cables. Verify all cabling limitations (particularly distance) before powering on the system.
Connect the Console Port and the Auxiliary Port
See Figure 20. The PRE module has two asynchronous serial (EIA/TIA-232) RJ-45 ports for connection to a console (an ASCII terminal or a PC running terminal emulation software) and modem for remote access. The cables and adapter are included in the accessory kit.
Equipment
•RJ-45 to RJ-45 crossover cable
•RJ-45 to DB-9 female DTE adapter (TERMINAL)
•RJ-45 to DB-25 male DCE adapter (MODEM)
Tip The crossover cable reverses the pins from one end of the cable to the other. The color of the wire at pin 1 is the same color as the wire at pin 8 on the opposite end of the cable (pin 2 to pin 7, pin 3 to pin 6, and so on.).
Console Port
The console port provides local administrative access to the router and its command-line interface (CLI).
Note Each PRE module must have a console port connection (typically to a terminal server) when running a redundant configuration in the chassis.
Step 1 Connect one end of the RJ-45 crossover cable to the serial RJ-45 port (labeled CONSOLE) on the PRE module.
Step 2 Run the other end of the crossover cable through the square hole at the left front side of the chassis, and connect it to the RJ-45-to-DB-9 adapter.
Step 3 Connect the adapter to the appropriate serial port on the PC or terminal to complete the console port cable connection.
Figure 20 Console and Auxiliary Port Connection on the PRE Module
Auxiliary Port
The auxiliary port provides a connection for a modem to allow remote access to the router and its command-line interface (CLI).
Step 1 Connect one end of the RJ-45 crossover cable to the serial RJ-45 port (labelled AUX) on the PRE module (Figure 20).
Step 2 Run the other end of the crossover cable through the square hole at the left front side of the chassis, and connect it to the RJ-45-to-DB-25 adapter.
Step 3 Connect the adapter to the serial port on the modem to complete the auxiliary port cable connection.
Connecting Ethernet Network Management Cables
The PRE module provides an Ethernet port to a LAN for a 10BASE-T or 100BASE-T connection for network management.
Note The PRE module also contains an internal Ethernet interface (ethernet0/0/0) that it uses for inter-module communications. This interface is invisible and transparent for normal operation. Do not confuse this internal interface, which is not user-accessible or user-configurable, with the PRE module's external Fast Ethernet interface (fastethernet0/0/0).
Note Each PRE module needs an Ethernet port connection (typically to the same Ethernet hub) if you are running a redundant configuration in the chassis. However, only the active PRE module has an active Ethernet connection to the network.
Equipment
•An Ethernet hub (such as a Cisco Micro Hub)
•An Ethernet cable that meets the following specifications:
–RJ-45 (male) to RJ-45 (male) straight-through cable (see Figure 21)
–100-ohm category 3, 4, or 5, no longer than 328 feet (100 meters)
Tip The color of the wire connected to pin 1 (left-most) on the connector at one end of the cable, should be the same color as the wire connected to the left-most pin on the connector at the other end of the cable. The same rule applies to pins 2 through pin 8 on each connector.
Figure 21 Straight-Through Cable
10BASE-T Ethernet Network
To connect the PRE to a 10BASE-T Ethernet LAN, follow this procedure:
Step 1 Connect one end of the Ethernet cable to the RJ-45 port on the primary PRE labeled Ethernet.
Step 2 Connect the other end of the cable to any unoccupied port on the Ethernet hub.
100BASE-T Ethernet Network
The RJ-45 port on the PRE is configurable for 100-Mbps full-duplex or half-duplex operation (half-duplex is the default) and supports IEEE 802.3, Ethernet, and IEEE 802.3u interfaces compliant with 100BASE-T specifications.
Caution If the Cisco uBR10012 router is used in an environment in which lightning-induced transients are likely to couple to the signal lines, use of shielded interconnection cables for the 100BASE-T ports is highly recommended. In addition, use of shielded interconnection cables for the 100BASE-T ports is required to meet Telcordia GR1089 CORE Section 4.5.9 and ETSI Section 5.2.2.2 (intra-building lightning surge).
To connect the PRE to a 100BASE-T Ethernet LAN, follow these steps:
Step 1 Connect one end of the Ethernet cable to the RJ-45 port on the primary PRE, labeled Ethernet.
Step 2 Run the cable up and through the cable management bracket and connect the other end of the Ethernet cable to any unoccupied port on the Ethernet hub.
Tip When power is applied to the chassis, check the LNK (Link) LED on the PRE faceplate port next to the Ethernet port. This LED comes on (green) if the PRE is correctly connected to the Ethernet LAN.
Connecting the Data Network Cables
Attenuation
The Cisco MC16C. Cisco MC16S, and MC28C line cards with the adapter card may require an attenuator in the downstream configuration. The output is higher (+42 dBmV) and may overload the external upconverter input. Overdriving an external upconverter may cause degraded bit error rate (BER), clipping and compression or distortion in the upconverter and possible interference with adjacent channels.
Note Neither the Cisco uBR-MC16E cable interface line card nor the Cisco uBR10-MC5X20S/U/H needs additional attenuation in the downstream path.
Upconverters
Table 4 lists the IF-to-RF upconverters that we recommend, and indicates whether a 10-dB attenuator is required.
Beginning with Cisco IOS Release 12.2(15)BC2, Cisco now supports IF muting with non-SNMP upconverters. In previous releases, IF muting was not available for non-SNMP upconverters and this limited the availability of N+1 redundancy in some circumstances. For additional information about IF muting and N+1 redundancy, refer to N+1 Redundancy for the Cisco Cable Modem Termination System at the following URL:
