Support for N+N Redundancy

The DGX A100 includes six power supply units (PSU) configured for 3+3 redundancy. If three
PSUs fail, the system will continue to operate at full power with the remaining three PSUs.
Note: If only two PSUs are working, the GPUs will not be available, but the server will still boot.
This is to allow you to gather debug or system logs.
If only one PSU is working, troubleshoot the cause for the loss of power from the other PSUs and
correct. If faulty PSUs need to be replaced, shut the system down and install working PSUs.
