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
