And you've checked all the aquabus cable connections between the EB8 and the base unit? Have you tried unplugging/replugging the aquabus cables or using a different connector port?
The orange lights on everything means the Apex isn't even talking to itself, so that's probably why you can't see it on the network. If disconnecting the aquabus (USB-looking) cables and reconnecting doesn't work, I'd disconnect everything and unplug the EB8 from the power outlet. Let it sit 30 minutes or so, and then plug things back in, but don't connect it to your router until you see green lights on the main unit and the EB8.
