Attach an antistatic wrist strap to yourself and to one of the two ESD connection sockets
located on the front edges of the upper card cage or to bare metal on the frame.
Proceeding from left to right, identify each line card and write down the following
information:
•
The slot number and type of line card.
•
The interface cable connections to the line card ports. You will need to reconnect the
interface cables to the same line card ports.
Proceeding from left to right in the upper card cage, select a line card. Starting with the
bottom port on the line card and working up (for cards with multiple ports only),
disconnect the network interface cable from the line card ports. Do not remove the cables
from the vertical cable-management bracket. (Refer to Figure 2.)
Loosen the captive screws at the top and bottom of the vertical cable-management
bracket. (Refer to Figure 2.)
Remove the vertical cable-management bracket from the line card and remove the
attached cables from the horizontal cable-management tray. Position the vertical
cable-management bracket out of the way of the horizontal cable-management tray.
Remove the four screws at the lower edge the horizontal cable-management tray. (Refer
to Figure 3.)
Pivot the bottom of the tray out, away from the frame, to disengage three horizontal
cable-management tray tabs (at the top of the tray) from the slots in the frame.
Remove the horizontal cable-management tray from the frame and set it aside.
