Attaching the Alarm Wires

For each alarm indicator being connected (minor, major, or critical), use two wires that are long enough to reach between the Cisco uBR10012 chassis and the alarm indicator equipment. Use the gauge of wire required by the audible or visual alarm indicator equipment you are using (14 AWG maximum gauge).

Warning Use copper conductors only. Statement 1025

Step 1 For each pair of wires, strip not more than 0.3 inches (8 mm) of insulation off of the ends of each wire (see Figure 5-5).

Figure 5-5 Stripping Insulation

Step 2 Connect one end of each pair of alarm indicator wires to the alarm terminal block as follows:

a. Connect one lead to the common (COM) terminal.

b. If you are wiring the router in series with other equipment for the alarm indicators, wire 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, wire the other lead to the normally open (NO) terminal.

Figure 5-6 shows the wiring configuration for normally open (NO) alarm relays.

Step 3 Connect the other end of this pair of alarm indicator wires to the appropriate connectors on the alarm indicator equipment. Route these cables through the square hole on the bottom right side of the chassis, as you face the front of the chassis.

Step 4 Repeat steps through 3 for the remaining alarm indicators.

Step 5 Secure the cabling to the chassis by feeding a tie wrap through one of the round holes next to the large hole on the side of the chassis. Then use the tie wrap to bind the cables to the chassis.

Step 7 Slide the PRE module out of the slot and place it on an antistatic surface, or in an antistatic bag (see Figure 5-9).

Figure 5-9 Removing the PRE Module from the Chassis

Step 8 If you are installing a new or replacement PRE module, proceed to the next step. Otherwise, install a blank cover over the slot and screw down its captive screws to conclude this procedure.

Note For proper cooling and airflow, a blank PRE module cover should always be installed when a second PRE module is not installed.

The product order number for the blank PRE module cover is ESR-PRE-COVER=.

Warning Blank faceplates and cover panels serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place. Statement 1029

Replacing the PRE Module

When replacing a PRE1 module with a PRE2 module, you must also install EMI gaskets and RF absorber material, for more information, go to the following URL:

http://www.cisco.com/en/US/docs/cable/cmts/ubr10012/installation/field_replaceable_units/pre2gkit.html

Step 1 Grasp the faceplate of the new PRE module with one hand and place your other hand under the card carrier (to support the weight of the module) and position the card in front of the card cage slot.

Step 2 Carefully align the upper and lower edges of the PRE module with the upper and lower guides in the chassis, and slide the module into the slot until you can feel it begin to seat in the backplane connectors (see Figure 5-10).

Figure 5-10 Inserting the PRE Module in the Chassis

Step 3 Simultaneously pivot both ejector levers toward each other (until they are parallel to the faceplate) to firmly seat the PRE module in the backplane (see Figure 5-11).

Step 4 Secure the PRE module in the chassis by tightening the top and bottom captive screws (see Figure 5-7).

Figure 5-11 Closing the Ejector Levers

Step 5 When fully inserted, the PRE module cycles through its power-on self-test. The FAIL LED stays on briefly (about 5 to 6 seconds) and then shuts off. If the FAIL LED remains on or is flashing, go to the “Troubleshooting Installation Problems” section.

Step 6 Reconnect any interface cables to the PRE module if necessary. Route the cables through the square hole in the front left side on the chassis.

Step 7 Install the PC media card in the PRE module, if necessary (see the Removing and Installing a PC Media Card).

Step 2 Remove any line cards from the splitter according to the “Removing a Half-Height Gigabit Ethernet Line Card” section.

The slot splitter does not have ejector levers to disengage cards from the backplane, so you must remove any line cards before you remove the splitter.

Step 3 Loosen the top and bottom captive screws on the slot splitter (Figure 5-25).

Figure 5-25 Captive Screw Locations

Step 4 Slide the splitter out of the slot (Figure 5-26).

Step 5 If you are not installing a replacement splitter or a line card, install a full-slot blank faceplate in the slot.

Figure 5-26 Removing the Slot Splitter

Installing the Slot Splitter

You must install the half-height line card into a slot that contains a slot splitter, which can hold two half-height line cards. If both slots of the slot splitter are not used, then you must install a blank faceplate in the empty slot.

Follow these steps to install a slot splitter into slot 3 or slot 4 of the Cisco uBR10012 chassis.

Step 1 Attach an antistatic wrist strap to your wrist and to an ESD socket on the chassis, or to a bare metal surface on the chassis or frame (Figure 5-21).

Do not operate the system unless all cards, faceplates, front covers, and rear covers are in place.
Statement 1029

Installing the Half-Height Gigabit Ethernet Line Card

Use the following procedure to install a HHGE line card into an installed slot splitter. See the “Installing the Slot Splitter” section to install the slot splitter.

If you are replacing a line card, see the “Removing a Half-Height Gigabit Ethernet Line Card” section before you begin this procedure.

Step 1 Attach an antistatic wrist strap to your wrist and to an ESD socket on the chassis, or to a bare metal surface on the chassis or frame.

Figure 5-29 Inserting the Line Card

Step 2 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 3 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 4 Be sure the ejectors are in the open position (as shown) and continue to push the line card into the splitter until you can feel it begin to seat in the backplane connectors.

Step 5 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 6 Simultaneously pivot both ejector levers toward each other (until they are parallel to the faceplate) to firmly seat the card in the backplane (Figure 5-22).

The 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 the HHGE Installation” section.

Step 7 Secure the line card in the slot splitter by tightening the top and bottom captive screws (Figure 5-31).

Types of SFP Modules

SFP modules from different manufacturers provide different methods for freeing the locking pin and removing the SFP module. Figure 5-32 shows two available module types.

Figure 5-32 Mylar Tab SFP Module and Bale Clasp SFP Module

• Mylar Tab SFP—Pulling the mylar tab simultaneously releases the locking pin and pulls the SFP module out of its receptacle.
• Bale Clasp SFP—Opening the bale clasp releases the locking pin so you can remove the SFP module from its receptacle.

Removing an SFP Module

Use the following procedure to remove an SFP module from the HHGE line card.

Note You can remove an SFP module while the system is powered on, but the interface shuts down.

Step 1 Attach an antistatic wrist strap to your wrist and to an ESD socket on the chassis, or to a bare metal surface on the chassis or frame.

Figure 5-33 Disconnecting the LC-type Fiber-Optic Cable

Step 2 Disconnect the fiber-optic cable connector from the SFP module (Figure 5-33).

Note which cable connector plug is TX and which is RX for reattachment.

Figure 5-34 Removing an SFP Module

Step 3 Unlock and remove the SFP module as follows:

a. Mylar Tab SFP Modules—Gently, but firmly pull the plastic tab to free the locking pin and remove the SFP module (Figure 5-34).

b. Bale Clasp Modules—Open the bale clasp to release the locking pin and remove the SFP module (Figure 5-34).

Step 4 Insert a dust plug into the optical ports of the removed SFP module to keep the optical interfaces clean, and place the module in an antistatic bag or other protective environment.

Inserting an SFP Module

Use the following procedure to insert an SFP module into the HHGE line card.

Step 1 Attach an antistatic wrist strap to your wrist and to an ESD socket on the chassis, or to a bare metal surface on the chassis or frame.

Figure 5-35 Inserting the SFP Module

Step 2 Gently insert the SFP module into the line card port until the edge connector is fully seated in the connector. You will hear a click as the triangular pin on the bottom of the SFP module snaps into place (Figure 5-35).

Step 3 Remove the dust plug from the SFP module optical ports and plug the LC-type fiber-optic cable connector into the SFP module (see Figure 5-35).

Removing the Cable Interface Line Card

Step 1 Attach an antistatic wrist strap to your wrist and to a bare metal, unpainted surface on the chassis or frame.

Step 2 Face the back of the Cisco uBR10012 chassis. Clear aside enough interface and power cables to allow sufficient space to work.

Step 3 If installing a new cable interface line card in a blank slot, remove the blank slot cover and discard. Otherwise, disconnect all coaxial cables from the cable interface line card being replaced or removed.

Step 4 Unscrew the top and bottom captive screws on the cable interface line card (see Figure 5-36).

Figure 5-36 Captive Screws, Ejector Levers

Step 5 Simultaneously pivot both ejector levers away from each other to disengage the cable interface line card from the backplane.

Step 6 Slide the cable interface line card out of the slot and place it on an antistatic surface, or in an antistatic bag (see Figure 5-37).

Figure 5-37 Removing the Cable Interface Line Card

Step 7 If you are installing a new or replacement cable interface line card, proceed to the next step. Otherwise, install a blank cover over the slot and screw down its captive screws to conclude this procedure.

Note For proper cooling and airflow, a blank cable interface line card cover must always be installed in a blank line card slot.

The product order number for the blank cable interface line card cover is UBR10-MC-Cover=.

Warning Blank faceplates (filler panels) serve three important functions: they prevent exposure to hazardous voltages and currents inside the chassis; they contain electromagnetic interference (EMI) that might disrupt other equipment; and they direct the flow of cooling air through the chassis. Do not operate the system unless all cards and faceplates are in place. Statement 1029

Installing a Cable Interface Line Card

Step 1 Grasp the faceplate of the new cable interface line card with one hand and place your other hand under the card carrier (to support the weight of the card) and position the card in front of the card cage slot.

Step 2 Carefully align the upper and lower edges of the cable interface line card with the upper and lower guides in the chassis, and slide the cable interface line card into the slot until you can feel it begin to seat in the backplane connectors (see Figure 5-38).

Figure 5-38 Inserting the Cable Interface Line Card

Step 3 Simultaneously pivot both ejector levers toward each other (until they are parallel to the faceplate) to firmly seat the card in the backplane (see Figure 5-39).

Figure 5-39 Closing the Ejector Levers

Step 4 Secure the cable interface line card in the chassis by tightening the top and bottom captive screws (see Figure 5-36).

Tip If you are installing more then one card, wait until all the cards are installed before tightening the captive screws.

Tip Captive screws prevent accidental removal and provide proper grounding for electromagnetic interference (EMI) shielding.

Step 5 When fully inserted, the cable interface line card cycles through its power-on self-test. The POWER LED lights (green) and the STATUS LED lights (yellow). If the card is operating correctly, the STATUS LED then starts lighting green. If these LEDs do not operate as described, see the “Troubleshooting the Line Cards” section.

Step 6 Connect all downstream and upstream coaxial cables to the cable interface line card as necessary.

Step 7 Configure the cable interface line card if necessary (refer to the Cisco uBR10012 Router Software Configuration Guide for information about configuring the line card).

Note It is not necessary to configure the cable interface line card if you are installing a replacement card in the identical slot. The system automatically downloads the necessary configuration information from the PRE.
