Power Connectors	Customers can provide power to a switch by using either the internal power supply 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 240 VAC. • Use the supplied AC power cord to connect the AC power connector to an AC power outlet.
Cisco RPS 675 Connector	• Offers connection for an optional Cisco RPS 675 that uses AC input and supplies DC output to the switch. • Offers a 675W RPS that supports up to 6 external network devices and provides power to 1 failed device at a time. • 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 675 (model PWR675-AC-RPS-N1=) should be attached to the RPS receptacle.
Indicators	• Per-port status LEDs: link integrity, disabled, activity, speed, and full-duplex indications • System-status LEDs: system, RPS, and bandwidth-utilization indications
