Chapter 6 Maintaining the Router

Removing and Installing an RP or a Line Card

The Cisco 12000 Series Router line cards use cable-management brackets for the following purposes:

•Organizing the network interface cables

•Keeping the network interface cables out of the way

•Positioning connectors at their respective ports on the line card faceplate

•Keeping the cables free of sharp bends (excessive bending in a network interface cable can cause performance degradation)

Note The type of cable-management bracket used by a line card is determined by the line card type and the number of network interface ports on the card faceplate.

To install the line card cable-management bracket, see Figure 6-29and follow these steps:

Step 1 Attach an ESD-preventive strap to your wrist and connect the leash to the chassis or to another grounded, bare metal surface.

Step 2 Take the line card cable-management bracket from the line card shipping carton.

Step 3 Orient the top of the line card cable-management bracket with the top of the line card faceplate (the end opposite the two four-character alphanumeric displays.)

Step 4 Align the two captive screws on the bracket with the threaded insert holes near the ejector levers on each end of the line card faceplate.

Step 5 Finger-tighten the two captive screws.

Caution Do not overtighten the captive screws; you might strip the threads on the screw or in the insert in the line card faceplate.

Step 6 Use a flat-blade screwdriver to secure the two captive screws.

Step 7 Repeat Step 2 through Step 6 for any remaining line cards.
