Using your Ethernet cable, connect your extender and ONU.

Hexagon extenders: port with globe icon or either port if there’s no globe icon
ONU: 10GigE port

Desk extender: 10G port
ONU: 10GigE port
If you received the optional network switch to connect more devices directly to Ethernet, connect it to the second Ethernet port on the extender connected to the ONU or either port of any additional extender(s).
It’s possible your extender will need to update before it connects. (This can take up to 10 minutes.)
