Power Connectors	● 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.
Indicators	● Per-port status LEDs: link integrity, disabled, activity, speed, and full-duplex indications ● System-status LEDs: system, RPS, and bandwidth-utilization indications
