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:
- Remove the power cord from the power supply unit.
- 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.
- Remove the power supply unit.

To insert a power supply unit:
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.
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.
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.
The system can fully operate if one fan FRU is dysfunctional. Failure of more than one fan is not supported.
To remove a fan unit:
When replacing a faulty fan unit in an operational switch system, do not leave the slot unpopulated for more than 60 seconds.
- Grasping the handle with your right hand, push the latch release (if exists) with your thumb, while pulling the handle outward. As the fan unit unseats, the fan unit status LEDs will turn off.
- Remove the fan unit.
