Line Card Cable-Management Bracket
Caution Do not use the cable-management bracket as a handle to pull out or push in the line card. The
cable-management bracket is designed to hold the interface cables and may break if you use the bracket
to push, pull, or carry the line card after it is removed from the router.
Removing and installing the line card cable-management bracket is described in the following
procedures:
• Removing a Line Card Cable-Management Bracket, page 38

Removing a Line Card Cable-Management Bracket
To remove a line card cable-management bracket, follow these steps:
Step 1 Attach an ESD-preventive wrist or ankle strap and follow its instructions for use.
Step 2 Note the current interface cable connections to the ports on each line card.
Step 3 Starting with the interface cable for the bottom port on the line card, disconnect the cable from the line
card interface.
Note It is not necessary to remove the interface cables from the line card cable-management bracket. The
bracket (with attached cables) can be hooked to the cable-management tray or a bracket on the chassis
until a new line card is installed.
Step 4 For multiport line card cable-management brackets, proceed upward and remove the interface from the
Velcro strap on the end of the cable standoff. (See Figure 32.)
For single-port line card cable-management brackets, carefully remove the interface cable from the cable
clip. (See Figure 33.) Avoid any kinks or sharp bends in the cable.
Step 5 Repeat Step 3 and Step 4 for all remaining interface cables, then proceed to Step 6.
Step 6 For multiport line card cable-management brackets, loosen the captive installation screw at each end of
the cable-management bracket and remove the bracket from the line card.
For single-port line card cable-management brackets, loosen the captive installation screw on the
cable-management bracket and remove the bracket from the line card.
