Optional Redundant Power Unit
Foundry provides an optional Redundant Power Unit (RPU) that can
supply power to the switch in the event of failure of the internal power
supply.
Power Supply Receptacles
There are two power receptacles on the rear panel of the switch. The
standard power receptacle is for the AC power cord. The receptacle
labeled “RPU” is for the optional Redundant Power Unit (RPU).
