Feature Description
– 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
