Troubleshooting power issues

If no lights illuminate when you connect the Ethernet cable to the phone and the touch screen remains dark, troubleshoot possible power issues.

1. If power for the phone comes from an Ethernet hub or switch, verify that the phone is connected to a PoE port.
   The phone must be connected to a PoE port, not a regular Ethernet port.
2. If power comes from a PoE injector, verify that the injector is plugged into a working AC outlet.
