NEC PowerMate CT manual Storing and Retrieving Unused Rails, Replacing a Bay Cover

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.

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 remove an old device, remove the rails and 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).
