You might need to install the cable-management arm. Use the procedure
in this section to perform this task.
To install the cable-management arm, complete the following steps:
From the back of the rack, locate the cable-management arm flange C located
on the fixed back portion of the left system rail assembly B.
Figure 1. Installing the cable-management arm.
Use pin F to pin the cable-management arm
E to the rack frame D.
Note: If access to the back of the rack is obscured by a large number
of existing cables, it might be easier to remove the small connecting hinge
from the cable-management arm and attach it first. Then, you can attach the
remaining section of the cable-management arm to the connecting hinge.
Use pin F to pin the other end of the cable-management
arm to the flange C attached to the sliding portion
of the left system rail assembly B.
Note: Ensure that the cable-management arm is level so that it moves
freely.
