Power Connector

The 10/100 hubs do not have a power switch; they are powered on when
connected to an active AC power source. The hubs automatically adjust to
various voltages (depending on the country) between 100-127 and 200-240
volts and either 50 or 60 Hz. There are no voltage range settings required.
