Removing the Housing's Bezel
1.Depress the latch at the top of the housing to open the bezel.
2.Lift upward to remove the bezel from the two slots at the bottom of the housing.
Save the bezel so it can be reattached once the APM has been installed.
NOTE:
The power supply is visible once the bezel is removed. It provides low voltage power to the housing and its cards.
!WARNING:
If you need to remove the power supply module, you must unplug the power cord from the power receptacle and from the rear of the housing before attempting to remove the module.
