1. Read the safety information that begins on page vii, and “Handling
static-sensitive devices” on page 31.
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 top cover (see “Removing the cover and bezel” on page 31).
Attention: To ensure proper system cooling, do not leave the top cover off the
server for more than 2 minutes.
3. Disconnect the power cord from the connector on the back of the power supply.
4. Press the locking latch on the power-supply handle and raise the power-supply
handle to the open position.
5. Lift the power supply out of the bay.
To install a hot-swap power supply, complete the following steps:
1. Raise the handle on the power supply to the open position.
2. Place the power supply into the bay and fully close the locking handle.
3. Connect one end of the power cord for the new power supply into the connector
on the back of the power supply, and connect the other end of the power cord
into a properly grounded electrical outlet.
