Hot-plug AC power supply
This procedure assumes that the server is configured with two power supplies.
CAUTION: To prevent improper cooling and thermal damage, do not operate the server unless all bays
are populated with either a component or a blank.
1. Perform one of the following:
• If a conventional cable management solution is in place, unfasten the cable management
solution to access the power supply bays.
• If the cable management arm is in place, access the rear panel ("Accessing the product rear
panel" on page 12).
2. Disconnect the power cord.
3. Press the power supply release lever, then pull the power supply from the server.
To replace the component, reverse the removal procedure.
Power supply fan assembly
CAUTION: Do not operate the server for long periods with the access panel open or removed. Operating
the server in this manner results in improper airflow and improper cooling that can lead to thermal damage.
1. Power down the server ("Powering down the server" on page 11).
2. Extend or remove the server from the rack ("Extending the server from the rack" on page 11).
3. Remove the access panel ("Removing the access panel" on page 13).
4. On models equipped with SATA drives, remove the SATA cable from the cable clip. For cable
locations, refer to the SATA cable routing information ("SATA cable routing" on page 36).
5. Press the latches and lift to release the power supply fan assembly from the server.
