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
Indicators
