8.8.2 Circuit Boards and Modules
Replaceable modules are shown in Figure 8.3. Ribbon cables and connectors are unique
and keyed to prevent the mis-connection of an appropriate connector in a location within
the power supply case. Fans use identical wiring harnesses, with one tying back the extra
lead length.
Make note of any wiring paths if you are removing a module, before you disassemble. In
some cases, there are several possible paths, but one preferred location. Be especially
careful with harnesses and wires that go between the two portions of the case, as they
can be pinched by the metal case if mis-routed.
8.8.3 Power Switch and Lamp
The Power Switch with its integral lamp is a field-replaceable component. It uses a 5-
conductor wiring harness. The switch leads are depicted, by color code, in Figure 8.4,
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.
