continues to run if one source fails, provided the remaining 4
power supplies are sufficient to deliver the required power.
With 3 PSUs, you must connect each one to a different source.
Thus 2+1 redundancy is supported; the system continues to
run if one source fails, provided the remaining 2 PSUs are
