Fwiw, I’ve had a few different PoE switches from Ubiquity and at least so far haven’t had any problems with the switches. My current one is the 48 Pro-Max etherlighting , and I have around fifteen PoE devices and it’s pretty much plug and play always.

I did have issues with some of their other products - eg an old CloudKey gen1 that I had remotely in my parents place that I think ran out of space to the point it can’t update itself and can’t compact some old mongodb.
