FRU Replacements
Power Supply
NVIDIA systems that are equipped with two replaceable power supply units work in a redundant
configuration. Either unit may be extracted without bringing down the system.
To extract a power supply unit:
The following information does not apply to the SN2100/SN2010 series. The SN2100/SN2010
systems include two non-replaceable power supply units and four non-replaceable fan units.

Make sure that the power supply unit that you are NOT replacing is showing green for the
power supply unit LED.

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
Air
Flow .
