Phone won't turn on
Check power and network when the screen stays blank.
Most office phones get power through the network cable (PoE).
Steps
- Check the network cable is firmly plugged into the port marked Internet, LAN or Network on the phone.
- Try a different wall port or switch port that you know works.
- If your office doesn't supply power over the cable, plug in the phone's power adapter.
- Try another phone on the same cable.If that also stays blank, the problem is the cable or switch.
