To replace a power supply:
1. Remove the replacement power supply from its shipping
container.
2. Inspect the rear of the power supply for bent or broken connector
pins. If any pins are damaged, obtain a new power supply.

connector, and the black plastic latch lever is completely down in
the horizontal position.

to the power supply and to a facility power source.
