Adtran ONT/NTU Light Status (Troubleshooting Guide) Print

If you're having trouble with your Adtran ONT (NTU) device, this guide will help you check the lights and reset your equipment before lodging a fault.

Adtran ONT Overview

Power Status Check

Ensure the device is plugged in and powered on:

• The Power light should be solid green (not flashing).
• Is the ONT plugged into a power point?
• Is there power coming into your property?

Your Adtran ONT may be installed in a cabinet like the one below.

Status Lights Check

• Check the ‘OPTICAL’ LED indicator light on the Adtran ONT. It should show a solid green light.
• Check the ‘LAN’ LED indicator light. It should be blinking green.
• Check the ‘ALARM/UPDATE’ LED indicator light. This should be off.

Restart

If all the above look correct, try restarting both devices:

1. Power off your router and the Lynham Adtran ONT.
2. Wait 10 minutes.
3. Power both devices back on.
4. Wait 5 minutes and re-check the light statuses above.
