Power connectors

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

• Use the supplied alternating-current (AC) power cord to connect the AC power connector to

Cisco RPS Connector

• The connector offers connection for an optional Cisco RPS 675 that uses AC input and

• The connector offers a 675-watt (W) RPS that supports up to 6 external network devices and

• The connector automatically senses when the internal power supply of a connected device

• Only the Cisco RPS 675 (model PWR675-AC-RPS-N1=) should be attached to the

Indicators

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

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