Power Supplies
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:
1. Remove the power cord from the power supply unit.
2. Grasping the handle with your hand, push the latch release with your thumb while
pulling the handle outward. As the power supply unit unseats, the power supply
unit status LEDs will turn off.
3. Remove the power supply unit.
To insert a power supply unit:
Important
Make sure that the power supply unit that you are NOT replacing is
showing green for the power supply unit LED without powering down
the system.
Important
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 (there are different power supply Part
Numbers to indicate the different airflow types).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.
