to the expansion unit and you might lose data.

To remove

a power supply:

1. Turn the switch on the power supply to the Off

position.

2. Unplug the supply power cord from the electrical

outlet.

3. Disconnect the power cord from the power supply.
4. Grasp each pull-ring and squeeze the latches to

release.

5. Pull open lever and remove power supply.

Note

When installing a new power supply, make sure that
the latch is mounted to the side of the supply that is
toward the middle of the machine. If not, remove the
lever screw, flip the lever over and replace the screw.
See the illustration above.
