7.7.3 Power Switch and Lamp
The Power Switch with its integral lamp is a field-replaceable component. It uses a 5-conductor wiring har-
ness. The switch leads are depicted, by color code, in Figure 7.4, Front Panel, Exploded Parts View, looking
at the bottom of the switch. To replace the switch, disconnect power and push the switch out from the rear
of the front bezel assembly. Disconnect the wires and, in reverse order, reinstall the new switch with the
integral lamp toward the top side.

You remove the Front Bezel by removing the four screws from the Bezel Support, and then lifting the Bezel
up and out.
