Network port use for WAX630 AP device with mesh connection

Hello,

I have a simple question to which I did not find the answer. If I connect a WAX630 device to an existing WAX620 AP wirelessly (so wireless backhaul) with instant mesh can I then connect a switch to the network port of that WAX630 and connect wired devices to it so they connect to the rest of the network or is this not possible and is the network port on the WAX630 "dead" when it's in mesh mode?

Thanks for your answer!
