Can Panoramic WiFi Pods use Ethernet Backhaul?

One of my pods keeps dropping off the network, despite being connected via ethernet back to a switch and then the gateway. I was under the assumption that if there was an ethernet connection, it would use that for backhaul, but I'm now thinking that this is a faulty assumption. 

I'm trying to get a firm answer on this, as the documentation doesn't specifically say it's possible, but some of the speeds I'm getting when connected lead me to think that this isn't just a wireless backhaul across approximately 75 feet. Of course that's before the AP drops, so I'm just not sure.

If the WiFi pods can't do ethernet backhauling, I need to either get more pods or different mesh network hardware that can use Ethernet backhaul.
