Serial numbers

Kerlink support team requires the serial number of the product to start treating support requests. Please join your gateway “Final product ID” each time you open a ticket.

Each Wirnet iFemtoCell has one global serial number, “Final product ID”, one “Board ID” and one “Packaging ID”.

The serial numbers of the product are on the gateway cardboard.

The Wirnet iFemtocell has one sticker placed on the back of the case. This sticker includes serial numbers (“Board ID” and “Final product ID”), MAC address, regulatory markings and electrical information.

"board_info.json" file

/tmp/board_info.json file is the system information file. It contains information about modules in the casing including the software versions. This file is generated at the boot of the gateway.

Below is the file structure:
