NBN FTTP Connection Box Status Lights

06Nov

by Mario Cadena

The article will explain the meaning of the status lights found on the NBN™ Connection Box (indoor unit) used for Fibre to the Premises (FTTP) services.
These lights may help you quickly check on the status of your NBN™ connection which may be useful when troubleshooting NBN™ FTTP issues.
Please note that the FTTP Connection Box should not be confused with the Connection Box for NBN™ Wireless.

Lifting the cover

From mid-2013 onwards, NBN™ Connection Boxes were installed with a plastic cover by default. To access the Connection Box, gently prise the bottom of the cover away from the two clips holding it in place at the bottom of the unit and then lift the cover upwards.

Are the lights behaving strangely?

If you’re seeing some really unusual behaviour such as the lights for unused UNI-D ports lit or flashing despite having nothing connected, have there been recent lightning storms in your area?

If you suspect the Connection Box, its cabling or other NBN™ equipment have been affected by a direct or nearby lightning strike, please contact us on 1300 820 216
