Power Connectors
You can provide power to a switch either by using the
internal power supply or the Cisco RPS 300. The
connectors are located at the back of the switch.
Internal Power Supply Connector
• The internal power supply is an auto-ranging unit
• 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
• Connection for an optional Cisco Redundant Power
System 300 (RPS 300) that uses AC input and supplies
DC output to the switch
• 300-watt redundant power system that can support
six external network devices and provides power to
one failed device at a time
• Automatically senses when the internal power supply
of a connected device fails and provides power to the
failed device, preventing loss of network traffic
• When internal power supply has been brought up or
replaced, the RPS 300 automatically stops powering
the device
• Attach only the Cisco RPS 300 (model
PWR300-AC-RPS-N1) to the RPS receptacle
Indicators
• Per-port status LEDs link integrity, disabled, activity,
speed, and full-duplex indications
• System status LEDs system, RPS, and bandwidth
utilization indications
