Redundant hot-plug power supply option
The server supports a second hot-plug power supply to provide redundant power to the system in the
event of a failure in the primary power supply. You can install or replace a second hot-plug power supply
without powering down the server.
CAUTION: If only one power supply is installed, do not remove the power supply unless the server has
been powered down. Removing the only operational power supply will cause an immediate power loss.
NOTE: To remove the primary hot-plug power supply, remove the shipping screw under the power supply
handle. Use the T-15 Torx screwdriver (" Rear panel components " on page 9 ).
