Power Connectors Customers can provide power to a switch by using either the internal power supply or the
Cisco Redundant Power System (RPS) 300. The internal power supply connector is located in
the front of the switch and the RPS connector is 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 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.
Indicators • Per-port status LEDs: link integrity, disabled, activity, and speed (uplinks only) indications.
• System status LEDs: system and RPS indications.
