Power and Startup Issues
The table Troubleshooting Power and Startup Issues describes possible solutions to several power and
startup issues.
Troubleshooting Power and Startup Issues
The phone has power issues or the phone has no power.
Determine if the problem is caused by the phone, the AC outlet, or the PoE switch. Do one of the following:
 Verify that no lights appear on the unit when it is powered up.
 Check if the phone is properly plugged into a functional AC outlet.
 Make sure that the phone isn't plugged into an outlet controlled by a light switch that is off.
 If plugged into a power strip, try plugging directly into a wall outlet instead.
