Rotating the Power Supply Away From the System Board

To access some components on the system board, you may have to rotate the system power supply out of the way. To rotate the power supply,
perform the following steps:

Remove the computer cover

2. Disconnect the AC power cable from the AC power receptacle on the back of the power supply (see Figure 7).

Figure 7. Rotating the Power Supply

3. Pull the green handle out and slide the power supply forward. With the handle pulled out, rotate the power supply down to a vertical position.

To return the power supply to its original position, perform the following steps.

1. Rotate the power supply to its original position and hold it there (see Figure 7).

2. Rotate the green handle towards the back of the system until it is closed.

Make sure the handle latches the power supply properly and the power supply slides slightly to the back of the system and locks in place.

Replace the cover

4. Reconnect the AC power cable to the AC power receptacle on the back of the power supply.
