Description

• 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.

• Per-port status LEDs: link integrity, disabled, activity, speed, and

full-duplex indications

• System status LEDs: system, RPS, and bandwidth utilization indications
