Chapter 4 Maintenance

4.2 Power Supply

When undertaking maintenance of the power supply, first shut off
all power input. Remove the rear panel (see Fig. 2-2). Unscrew the
four screws under the power supply. The power supply and its
bracket should now be detached from the case. Detach all power
connectors linked to the accessory drives and other components.
For the AWS-8430 models, pull out the connectors on the front
switch. Then remove the power supply kit from the system (see
Fig. 4-2). For the AWS-8430T/T-T (ISA backplane) model, disas-
semble the unit as far as the front panel (see Fig. 1-2). Then
disconnect the switch connector and take out the power supply.

Warning: Shut off all power to the AWS-8430 before you

commence to repair the power supply. Switch off
the power and unplug the unit.
