Specification
Customers can provide power to a switch by using either the internal power
supply or the Cisco RPS 675. The connectors are 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 volts
alternating current (VAC).
• Use the supplied alternating-current (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 675 that uses AC
input and supplies direct-current (DC) output to the switch.
• The connector offers a 675-watt (W) RPS that supports up to 6 external network
devices and provides power to 1 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.
• Only the Cisco RPS 675 (model PWR675-AC-RPS-N1=) should be attached 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
