There is a switch on the right hand side of the power supply module that selects
mains voltage. The mains voltage can be either 110VAC or 230VAC. This
switch must be set in the correct position, depending on the mains voltage on
the router’s site.
Failing to select correct AC mains voltage properly may damage the
Power Supply Unit.
