1. Read the safety information in “Working inside the server with the power on”

on page 66.

2. Place the new power supply into the bay.

3. Tighten the captive thumbscrew at the rear of the power supply to secure the

power supply to the chassis bottom.

4. Replace the rear screw, which holds the power supply to the rear of the

chassis (see the illustration on page 85).

5. Make sure that the air deflector is in the open position.

6. Connect the internal power-supply cable from the power supply to the power

connector (CN20) on the system board (see “System-board internal

connectors” on page 6).

7. Route the other internal power-supply cable, securing it under the

retention-clips on the chassis; then, reconnect the cable to the CD/DVD

interface card.
