●  Customers can provide power to a switch by using either the internal power supply or a redundant power system (Cisco RPS 2300 or the Cisco RPS 675). The connectors are located at the back of the switch.

● Internal power supply connector

●  The internal power supply is an autoranging unit.

●  The internal power supply supports input voltages between 100 and 240VAC.

●  Use the supplied AC power cord to connect the AC power connector to an AC power outlet.

●  Cisco RPS Connector

●  The connector offers connection for an optional Cisco RPS 2300 or RPS 675 that uses AC input and supplies DC output to the switch.

•  The connector automatically senses when the internal power supply of a connected device fails and provides power to the failed device, preventing loss of network traffic.

●  Only the Cisco RPS 2300 (model PWR-RPS2300) or the Cisco RPS 675 (PWR675-AC-RPS-N1=) should be attached to the redundant-power-supply receptacle.
