The front bezel and top cover are removed for most maintenance
procedures.
To replace the top cover and bezel:
Position the top cover so that the latch hook is in back, and
the rail hooks face towards the rear of the machine. See figure
Removing or replacing the cover.
Set the cover on the chassis so that it is aligned with the
sides and slightly overhangs the front of the machine.
Slide the cover towards the back of the machine until it is
flush with the chassis.
For a rack-mount unit: Slide the machine back into the
cabinet.
Note: If you unplugged any cables, reconnect them
now. See figure:
