possible solutions to them. The VoIP Router can be easily monitored
through panel indicators to identify problems.

• Check connections between the VoIP
Router, the external power supply, and the
wall outlet.

If the power indicator does not turn on when
the power cord is plugged in, you may have
a problem with the power outlet, power cord,
or external power supply. However, if the unit
powers off after running for a while, check
for loose power connections, power losses,
or surges at the power outlet. If you still
cannot isolate the problem, then the external
power supply may be defective. In this case,
contact Technical Support for assistance.
