Chapter 12

Replacing the Power Supply and

Fuses

This chapter describes how to replace a failed power supply. The last section in this
chapter describes how to replace the tape/disk fuse in the power supply.

WARNING: The inside of power supply contains high voltage that can be

present even after the supply is disconnected from the ac
power source. Never remove the cover of the power supply or
attempt to service the power supply.

Removing the Power Supply

Before you can remove the power supply, you need to power down any peripherals and
the computerunit, and remove the computerunit's top and left side covers as
described in the Opening the ComputerUnit" section of Chapter6. Make certain you
unplug the power cord from the ac power outlet and from the receptacle on the back of
the computerunit

before

removing the covers.

1.

Unplug the ac powerand fan assembly powercables from the powersupply as
shown in Figure 12Ć1.
