Check for power on the phone terminal

ComplexityEasy

If lights don’t display on the front of the terminal, you may have a power issue. The lights are on the opposite side of the terminal from where the cords plug in.

Follow these steps if there are no lights on the terminal.

If lights don’t display on the front of the terminal, you may have a power issue. The lights are on the opposite side of the terminal from where the cords plug in.

Follow these steps if there are no lights on the terminal.

  1. Unplug and then immediately plug in the power cord from both ends, including the end in the wall outlet and the end on the back of the phone terminal.
  2. Check again for lights on the front of the terminal.
  3. If lights still don’t display, plug a phone charger or any other handy electrical device into the same wall outlet currently being used by the phone terminal.
  4. If that wall outlet doesn’t provide power to the other electrical device, then the wall outlet needs to be fixed.
    • Temporarily plug the phone terminal power cord into another wall outlet.
    • Call an electrician. Shaw Business technicians can’t fix power issues.
  5. If the wall outlet does provide power to the other electrical device, but lights don’t return to the phone terminal, then the terminal needs to be fixed. Contact Business Technical Support.

Reset the phone terminal

ComplexityMedium

If your phone lines do not work but the phone terminal has power and is online, it may be frozen and may need to be reset. The best fix is to fully disconnect the power by removing both the power cord and the battery backup. There is a reset button on the terminal, but this should only be used if disconnecting the power is too difficult.
