Replacing the Power Supply

1 Follow the procedures in "Before You Begin" on page 143.
2 Remove the computer cover (see "Removing the Computer Cover" on
page 147).
3 Disconnect the DC power cables from the system board and the drives.
Note the routing of the DC power cables underneath the tabs in the
computer chassis as you remove them from the system board and drives.
You must route these cables properly when you replace them to prevent
them from being pinched or crimped.
4 Remove the hard drive cable, CD or DVD drive data cable, front panel
ribbon cable, and any other cables from the securing clip on the side of the
power supply.
5 Remove the four screws that attach the power supply to the back of the
