Removing and Installing the Front Bezel
The NMS-A-25 engine comes with an optional front panel bezel that can be
attached to the front of the chassis by snapping the bezel onto the chassis
handles. A key lock allows you to lock the bezel in place so that front panel
controls cannot be used. You can still monitor system status indicators with the
bezel in place.
Removing the Front Bezel
To remove the front bezel:
1. Unlock the bezel if it is locked.
2. Remove the left end of the front bezel from rack handle.
3. Rotate the front bezel counterclockwise to release the latches on the right end from
the rack handle.
Installing the Front Bezel
Note: Before installing the bezel, you must install the rack handles. See
