Connecting to the Tether Network

Carefully open the tether interface box. Do it slowly and take pictures so you can get it back together again.

You're looking for the connecting cable between the Fathom-X PCB and the Ethernet-to-USB dongle. Disconnect the cable from the dongle, and plug another flat 6"/150mm Ethernet cable into the dongle. You should now have two loose Ethernet connectors. These will be routed out of the box and plug into two ports on the switch.
