Removing and Installing the Back Door Stabilizer Bars
The top and bottom bars used to stabilize the back doors can be removed,
making it easier to route cables through the top and bottom of the rack.
1 Open the back doors.
2 Pull and hold the plungers on each side of the bar, and move the bar up
and away from the rack. See Figure 23.
3 Route the cables and replace the bars by aligning the tabs on the bars with
the corresponding holes in the rack.
4 Push the plungers until they lock into place.
