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.

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.
