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

Cisco RPS. The RPS 300 is compatible with all Catalyst 3550 models except the 3550-24-DC

and 3550-24 PWR. The RPS 675 is compatible with all Catalyst 3550 models except the

3550-24-DC. 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 675-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 675 (model PWR675-AC-RPS-NI=) to the redundant power supply

receptacle with this connector. See above for Catalyst 3550 RPS compatibility.

Cisco RPS 300 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 with this connector. See above for Catalyst 3550 RPS compatibility.
