I know there isn't a troubleshooting guide yet, so I had to go explore my options. The topside adapter is good to go, all three lights are up as expected. When I took a look at the Controller Board, here is what I have:
The BTX and BRX lights are not illuminating, but the BBB obviously has a connection to the Homeplug. I tried swapping out Ethernet cables on the E-Chassis because I remember someone earlier had an issue with the patch cable. But no joy for me.
Any thoughts about what's going on here?
