4.Rotate the power supply up and out of the way of the system board (see Figure 20).

5.Disconnect the power supply connectors from the POWER_1 and POWER_2 connectors on the system board.

6.Carefully fold the DC power supply cables you have disconnected and place them outside the chassis.

7.With the power supply in its rotated position up and away from the system board and chassis, lift up on the front end of the power supply, and then move that end of the power supply out, away from the chassis (see Figure 21).
