Maintaining the Cisco12008 7-77
Removing and Replacing the Cable Management System
Installing a Cable-Management Bracket
For the procedure in this section, it is assumed that you have installed a new line card in the
router, in which case you must also install a cable-management bracket on the card. A small
hook on the top of the cable-management bracket allows you to hook the bracket onto small
cutouts on the cable-management tray during a line card replacement procedure.
Note Before accessing any of the routers internal components, put on an antistatic wrist
strap and make sure that it makes adequate contact with your skin. Insert the equipment end
of the wrist strap (the banana jack) into the ESD grounding socket on the lower left edge of
the upper card cage (see Figure 7-24).
To install a cable-management bracket on a line card, perform the following steps:
Step1 Attach the cable-management bracket to the line card by means of the two
captive installation screws at the top and bottom of the cable-management
bracket (see Figure7-28).
Step2 Carefully arrange the interface cables in the cable-management tray (for line
cards with multiple ports); determine the appropriate length of each cable for the
intended port and route the cables down to the line card ports.
Step3 Starting with the bottom port on the line card, connect the interface cables to the
intended port (see Figure7-29, part 1).
Step4 Carefully press the interface cable into the associated cable keeper clip on the
cable-management bracket clip (see Figure7-29, part 2). Avoid any kinks or
sharp bends in the cable.
Step5 Proceeding upward, carefully press the interface cable between the metal fingers
that support the cable keeper clips (see Figure7-29, part 3).
Step6 Go back to Step3 and proceed through the cable attachment procedure in a
bottom-to-top direction until you have attached all the interface cables to the line
card ports.
This completes the installation procedure for the Cisco 12008 cable-management bracket.
