NBN FTTP Connection Box Status Lights
The article will explain the status lights found on the NBN® Connection Box (indoor unit) used for Fibre to the Premises (FTTP) services, which may be useful when troubleshooting NBN FTTP issues.
It will also show you where to find the Connection Box's Serial Number, which may be required to complete your NBN order.
Lifting the cover
NBN FTTP Connection Boxes may have a plastic cover. To open
it, 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.
Once lifted, the Connection Box will be partially covered by casing, but you will still be able to see the status lights and access the ports as shown below.
Location of Serial Number
You'll see a barcode sticker on the right-hand side of the box. The number next to S/N is the Connection Box's Serial Number, as shown below.

Are the lights behaving strangely?
If you're seeing some really unusual behavior 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 lightning strike, please contact us for further support.
