Upgrading Your Server 9-15
Replacing a Failing Power Supply Unit
Replace only a failing power supply unit.
IMPORTANT:
Do not remove a power supply unit operating
normally.
NOTE:
If two power supply units work normally while the server
contains three or four power supply units in a redundant configuration,
the failing power supply unit can be replaced with the system operating
(power-on state). (Skip step 2.)
1.
Check the POWER lamp on the power supply unit and determine which unit needs to be
replaced.
The lamp of the failing power supply unit is off.
2.
Shutdown the system, and turn off the server.
3.
While pressing down on the locking tab, grasp the handle and carefully pull the power
supply unit out of the power supply bay.
IMPORTANT:
To avoid damaging the power supply unit and/or
connector, do not tilt or twist the unit as you pull it from the power
supply bay. Use even, steady force to remove the unit.
