Power supply
The server supports three or six hot-plug power supplies. Six are required to provide 3+3
redundant power to the system in the event of a failure in a primary power supply. You can
install or replace a redundant hot-plug power supply without powering down the server.
WARNING! To reduce the risk of electric shock, do not disassemble the power supply or attempt
to repair it. Replace it only with the specified replacement part.
CAUTION: If only three power supply are installed, do not remove a power supply unless the
server has been powered down. Removing a primary operational power supply causes an
immediate power loss to the server.
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.
IMPORTANT: For maximum server availability, be sure that the primary and redundant power
supplies are powered by separate ac power sources.
See “Power supply LED” (page 70) for information on the current status of the power supply.
To remove a power supply:
1.
Disconnect the power cord from the power supply.
2. Press the thumb lever.
