3-20 Disassembly and Reassembly
Replacing a Bay Cover
Replace a bay cover on a bay as follows.
Note Place unused rails back in the empty bay before attempting to replace a bay cover. The
bay cover cannot be secured over the bay if the rails are absent.
1. If necessary, put the rails back in the bay. The cover cannot be secured if there are no rails
within the bay. (See the next section, “Storing and Retrieving Unused Rails.”)
2. Position the cover so the arrows on either side point up for the chassis orientation you are
using.
3. Line up the cover tabs with the slots on the rails. These slots are about 1/4 inch in from the
ends of the rails (see the following figure).
4. Place each cover tab in its slot.

Replacing a Bay Cover

A – Slot on Rail C – Bay Cover
B – Tab on Bay Cover
Note: Rails are shown partially out of the system in this figure to show in detail the tabs at the
end of each rail; make sure rails are fully inserted before attaching a bay cover.
Storing and Retrieving Unused Rails
The device rails on the 5 1/4-inch devices in the system are designed specially for the chassis. If
the system has an unused 5 1/4-inch bay, there should be rails stored within it. Use these rails on
new devices (if necessary). If you r e move an old device, remove the rails a nd store them. If
there is an empty 5 1/4-inch bay, store the rails in the chassis; otherwise set the rails aside for
future use.
To store a rail in an empty bay:
1. Position the end of the rail in the guides within the bay. The underside of the rail should be
to the wall of the bay. The tab should be angled away from the center of the bay (see the
following figure).
