Equipment to Take When Moving

I am moving from one Telus Fibre city to another and was told to take my existing equipment when moving to the new location. I know that includes the black wifi modem and the two TV boxes, but there are also two white boxes in the connection cabinet - a small white box slightly larger than a pack of cards that connects directly to the fibre optic link, and a second larger white box (Nokia) that looks similar to the black modem. Do I leave both white boxes or take the larger one that is between the fibre connection and the black modem?
