It automatically senses when the internal power supply of a connected device fails and provides power to the failed device, preventing loss of network traffic. For more information on the Cisco RPS 300, refer to the Cisco RPS 300 Redundant Power System Hardware Installation Guide. The Cisco RPS 675 has two output levels: -48V and 12V with a total maximum output power of 675W. Use the supplied RPS connector cable to connect the RPS to the switch.
