Replacing the Power Supply

WARNING To prevent injury, unplug the workstation’s power cord from the electrical outlet before replacing the power supply.

Perform the following steps to replace the power supply:

1.Open the left side panel of the workstation as shown in the section “Opening the Left Side Panel.”

2.Place the power supply on the floor of the workstation chassis. The power supply must be positioned such that its fan is pointing left toward the rear of the workstation, and its cabling is coming out of the bottom, right side of the power supply.

3.Slide the power supply towards the rear of the workstation. You must engage the hook on the bottom of the power supply into the support strap in the chassis floor.

4.Screw in the four T-15 Torx screws that hold the power supply in place into the rear of the chassis, as shown in Figure 4-46.

5.Reattach the bundled power cables in the cable management clips on the chassis floor. See Figure 4-46.

6.Connect the power cable to the rear of the floppy disk drive, if the optional floppy disk drive is installed. Then replace the cover of the floppy disk drive bay. To do this, see “Replacing or Installing a Floppy Disk Drive” on page 99.

7.Connect the power cable to the rear of the CD drive and then replace the cover of the floppy disk drive bay. To do this, see “Removing and Replacing a CD Drive” on page 91.

8.Plug the two power supply cables into the system board.

9.Close the left side panel of the workstation as shown in the section “Closing the Left Side Panel.”
