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.
The AC power connector is on the front panel of the Catalyst 2950ST-8 LRE and Catalyst 2950ST-24
