To extract a power supply unit:
Remove the power cord from the power supply unit.

Remove the power supply unit.
PS Unit Pulled Out
To insert a power supply unit:
Make sure the mating connector of the new unit is free of any dirt and/or obstacles.
Insert the power supply unit by sliding it into the opening, until a slight resistance is felt.
Continue pressing the power supply unit until it seats completely. The latch will snap into
place, confirming the proper installation.
Insert the power cord into the supply connector.
Insert the other end of the power cord into an outlet of the correct voltage.
Fans
The system can fully operate if one fan FRU is dysfunctional or missing. Failure of more than one fan
is not supported.
Make sure that the power supply unit that you are NOT replacing is showing all green, for
both the power supply unit and System Status LEDs.
Power supply units have directional air flows similar to the fan module. The fan module
airflow must coincide with the airflow of all of the power supply units. If the power supply
unit airflow direction is different from the fan module airflow direction, the system’s
internal temperature will be affected. For power supply unit air flow direction, refer to
.
Do not attempt to insert a power supply unit with a power cord connected to it.
The green power supply unit indicator should light. If it does not, repeat the whole
procedure to extract the power supply unit and re-insert it.
