Replacing the Rack Doors

CAUTION: To prevent personal injury due to the size and weight of the
doors, never attempt to replace the doors by yourself.
To replace the 42-U rack's front and back doors, perform the following steps:
1. Lift the front door into position, and align the hinges with the holes in the rack as
shown in Figure 1-3.
2. Slide the hinges into the holes in the rack until the hinge release levers lock the
hinges into position.
3. Verify that the hinges are latched.
4. Close the door latch by rotating the handle counterclockwise until it stops, push
in the handle until it locks in position, and then slide the cover down over the
push button (see Figure 1-2).
5. Repeat steps 1 through 4 to install the back door.
