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.
This article will also explain where to find the Connection Box’s Serial Number, which may be required in order to complete an order for NBN™ services.
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.
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
Once the cover is lifted, 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.
