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 pull the bar up
and away from the rack (see Figure 1-17).
3 After routing your cables, replace the bars by aligning the tabs on the bars
with the corresponding holes in the rack and pushing in and down until
the plungers lock into place.
