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.
