 To insert a power supply unit:
Step 1.
Make sure the mating connector of the new unit is free of any dirt and/or obstacles.
Do not attempt to insert a power supply unit with a power cord connected to it.
Step 2.
Insert the power supply unit by sliding it into the opening until a slight resistance is felt.
Step 3.
Continue pressing the power supply unit until it seats completely. The latch will snap into
place, confirming the proper installation.
Step 4.
Insert the power cord into the supply connector.
Step 5.
Insert the other end of the power cord into an outlet of the correct voltage.
The green power supply unit indicator should light. If not, repeat the whole procedure
to extract the power supply unit and re-insert it.
2.8.2 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 fans have the air flow that matches the model number. An air flow
opposite to the system design will cause the system to operate at a higher (less than
optimal) temperature.
For power supply unit air flow direction, refer to Section 2.2 on page 13
