Replacing a Failing Power Supply Unit
Replace only a failing power supply unit.
Caution
Do not remove a power supply unit operating normally.
Note: If one power supply unit fails while the server
contains two power supply units in a redundant configuration,
the failing power supply unit can be replaced with the system
operating (power-on state).
1. Locate the failing power supply unit by the AC POWER lamp on the rear of
each power supply unit. (The lamp of the failing power supply unit is amber.)
2. Shutdown the server.
3. To turn off the power, press the POWER switch.
4. Disconnect the power cord from the failing power supply unit.
5. Hold the handle of the failing power supply unit.
6. While pressing the lever (1), pull the power supply unit (2) to remove if from
the chassis.
Figure 114: Removing the Power Supply form the Chassis
7. If operating the server with a single power supply unit without installing a new
one, install the blank cover you removed in “Hold and pull the lever of the
blank cover and remove the blank cover.” on page 170 of power supply unit
installation procedure.
