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
