RPS12 external redundant power supply
The external redundant power supply (RPS12) can supply backup power to one of four connected
devices in the event of an AC loss or failure of an internal power supply. The system supplies the
failed device with up to 120 W for primary 12 VDC power, and up to 780 W of -54 VDC PoE power
(for PoE devices connected to the failed device).
The RPS12 monitors the power status for all attached devices and provides power to first device
with a detected power failure. The RPS12 supports the full load of the device without affecting
network operation. When the RPS12 is supplying power to a device, it cannot provide power to
other connected devices.
