Step6 Once all of the line card interface cables are removed, loosen the captive installation screws at the top and bottom of the cable-management bracket (see Figure7-27). 7-76 Step7 Remove the cable-management bracket from the line card. This completes the removal procedure for the Cisco 12008 cable-management bracket.
