To remove a hot-swap power supply, complete the following steps:
1. Read the safety information that begins on page v and "Installation guidelines"
on page 21.
Attention: Static electricity that is released to internal server components
when the server is powered-on might cause the server to halt, which could
result in the loss of data. To avoid this potential problem, always use an
electrostatic-discharge wrist strap or other grounding system when working
inside the server with the power on.
2. Remove the server cover. See "Removing the cover and bezel" on page 23.
3. If you are adding a power supply to an empty power-supply bay, remove the
cover from the ac power connector opening on the rear of the server.
4. If you are replacing a failed power supply, remove the failed power supply from
the bay:
a. Disconnect the power cord from the connector on the back of the failed
power supply.
b. Press the locking latch on the power-supply handle and raise the
power-supply handle to the open position.
c. Lift the failed power supply out of the bay.
5. Raise the handle on the new power supply to the open position.
6. Place the new power supply into the power-supply bay in the chassis and fully
close the locking handle.
