1. Ensure your phone is properly plugged into a functional AC outlet.
2. Ensure that the phone isn’t plugged into a plug controlled by a switch that is off.
3. If the phone is plugged into a power strip, try plugging it directly into a wall
outlet instead.
4. If your phone is powered from PoE, ensure you use a PoE compliant switch or
hub, or contact your system administrator for more information.
5. Check that the power LED is on to ensure the phone is powered on.
