Optional Redundant Power Unit
SMC supports 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 Sockets

standard power socket is for the AC power cord. The socket labeled
“RPU” is for the optional Redundant Power Unit (RPU).
