Back of the Switch

Power Connector

The Switch 2520G-24-PoE does not have a power switch; it is powered on 
when connected to an active AC power source. The switch automatically 
adjusts to any voltage between 100-127 and 200-240 volts and either 50 or 
60 Hz. There are no voltage range settings required.

The Switch 2520G-8-PoE also does not have a power switch. It is powered on 
when the external AC/DC power adapter is connected to the switch and to a 
power source. The external AC/DC power adapter supplies 48 volts DC to the 
switch and automatically adjusts to any AC voltage between 100-240 volts and 
either 50 or 60 Hz. No voltage range settings are required.
