Description Specification

Power Connectors Customers can provide power to a switch by using either the internal power supply or the Cisco Redundant

Power System (RPS) 300. 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 Connector

• The connector offers connection for an optional Cisco RPS 300 that uses AC input and supplies DC output

to the switch.

• The connector offers a 300-watt redundant power system that can support 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 300 (model PWR300-AC-RPS-N1) to the redundant-power-supply receptacle.
