Power	Customers can provide power to a switch by using the internal power supply, the Cisco RPS 675
connectors	Redundant Power System. The connectors are located at the back of the switch.
	Internal power supply connector:
	• The internal power supply is an auto-ranging 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:
	• The connector offers connection for an optional Cisco RPS 675 that uses AC input and supplies
	DC output to the switch.
	• The connector offers a 675W redundant power system that supports six external network
	devices and provides power to one failed device at a time.
	• 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.
	• Attach only the Cisco RPS 675 (Model PWR675-AC-RPS-NI=) to the redundant power supply
	receptacle with this connector.
Indicators	• Per-port status LEDs: link integrity, disabled, activity, speed, and full-duplex indications
	• System status LEDs: system, RPS, and bandwidth-utilization indications
