PSU Redundancy
Up to four PSUs can be installed in the front of each chassis. The chassis can support a mix
of AC and DC power supplies.
For the 7750 SR-a4, one PSU can support the full system power requirements if you are
operating without power redundancy. For redundancy, at least two PSUs must be installed
and powered at all times.
