Optional Redundant Power Supply
The switch supports an optional Redundant Power Supply (RPS), that can supply
power to the switch in the event the internal power supply fails.
Power Supply Sockets
There are two power sockets on the rear panel of each switch. The standard power
socket is for the AC power cord. The socket labeled “RPS” is for the optional
Redundant Power Supply (RPS).
