What to do if my Polycom IP Phone has no power?
- C
  Christian ShannonAug 18, 2025
  If your Polycom IP Phone has no power, please try the following: Verify that no lights appear on the phone when it is powered up. Check if the phone is properly plugged into a functional AC outlet and that it isn't controlled by a light switch that is off. If it's plugged into a power strip, try plugging it directly into a wall outlet. You can also try the phone in another room to test a particular outlet.

  Brenda AndersonAug 20, 2025
  If there is no display, the display is incorrect, or the display has bad contrast on your Polycom IP Phone, ensure the display is illuminated. Also, make sure the LAN cable is properly inserted at the rear of the phone by unplugging and re-inserting it. If you're using Power over Ethernet (PoE), ask your system administrator to check that the switch is supplying power to the phone.

  If the dial pad on your Polycom IP Phone does not respond, check for a response from other feature keys or from the dial pad.

From the Ethernet page, scroll to the LAN port field and verify that it is active. Check the termination at the switch or hub end of the network LAN cable.
