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
