Power Connectors
You can provide power to a switch by using the AC internal power supply, the
DC-input power source, or the Cisco RPS.
Internal Power Supply Connector
The internal AC power supply is an autoranging unit that supports input voltages
between 100 and 240 VAC. Other than for the Catalyst 2950G-24-EI-DC and the
Catalyst 2950ST-24 LRE 997 switches, use the supplied AC power cord to
connect the AC power connector to an AC power outlet.
Note
The AC power connector is on the front panel of the Catalyst 2950ST-8 LRE and
Catalyst 2950ST-24 LRE switches.
You can order these L-shaped AC power cords from your Cisco sales
