Tip: If access to the back of the rack is obscured by many 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 the second pin (F) to pin the other end of the cable-management arm to the flange (C) that is
attached to the sliding portion of the left system rail assembly (B) . See Figure 31.
Connecting the power cables to the system
You might need to connect power cables to the system. Use this procedure to perform this task.
To connect power cables to the system, follow these steps:
1. While facing the rear of the system unit, note the bottom tab of the cable-restraint bracket. Turn the
cable-restraint bracket counter-clockwise to a horizontal position, and insert the bottom tab of the
cable-restraint bracket into the bottom hole in the rail. Then rotate the cable-restraint bracket
clockwise to the vertical position as shown in Figure 32 on page 38. Insert the system power cord
through the cable-restraint bracket as shown in this figure. Then press down on the top of the bracket
and insert the top tab into the top hole.
Note: There are two sets of holes on the rail where the cable-restraint bracket can be installed. These
sets of holes are about 25.4 mm (1 inch) apart. Install the bracket in the rear most set of holes.
