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 auto-ranging unit.

• The internal power supply supports input voltages between 100 and 240 volts

alternating current (VAC).

• Use the supplied alternating-current (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 675 that uses AC

input and supplies direct-current (DC) output to the switch.

• The connector offers a 675-watt (W) RPS that supports up to 6 external network

devices and provides power to 1 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.

• Only the Cisco RPS 675 (model 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
