REMOVAL AND REPLACEMENT OF COMPONENTS

Chapter 4

Reinstall the system fan assembly (page 80).

Power Supply

Disconnect power from the system (

page 68

), remove the access panel (

page 74

), remove the

system fan assembly (

page 80

), and lay the workstation on its side with the system board facing up.

Disconnect the power supply from the system board.

Disconnect the optical drives, diskette drive, hard drives, and graphics card (select models only) from

the power supply.

CAUTION

Be sure you can differentiate which power cable was disconnected from the PCI Express x16

graphics card and which power cable was disconnected from the system board. These two cables look

very similar. The PCI Express power cable has a black connector and the power cable has a white

connector. When power is present, you must NEVER connect the PCI Express power cable to the

system board. If you do so, the system board may be damaged and your warranty voided. To see a

picture of the PCI Express cable and where it must be connected, refer to the “PCI or PCI Express

Installation” section on page 91.

Remove the four screws

from the back panel.

Slide the power supply toward the front and lift up

to remove it from the chassis.

To install the power supply, reverse the previous steps.
