Interesting, can’t say I’m aware of other reports of this. At first glance, the most obvious thing could be cables, but if PoE is off, then that shouldn’t be relevant.
You can use this via shell to check the port status poe -p 0, which should give you the details (port count starts at 0 with this command, so interface 1 is 0, interface 2 is 1, etc). Specifically there is an Enabled parameter, and it should so 0 when PoE on the port is disabled.
Do you have a free PoE port? If so, what happens if you turn off PoE on that port and move this node to that port? Does the issue follow?
