Rear Panel Description

The rear panel of the Switch contains an AC power connector.
The AC power connector is a standard three-pronged connector that supports the power cord. Plug-in the female connector
of the provided power cord into this socket, and the male side of the cord into a power outlet. The Switch automatically
adjusts its power setting to any supply voltage in the range from 100 ~ 240 VAC at 50 ~ 60 Hz.
