I did a stupid thing and accidentally connected unifi ubiquiti ethernet cable into VU+ Ultimo 4k's ethernet port. Unifi's POE injector is of the dumb type and it always sends 24V over the ethernet cable. LAN actually worked while I did that, and I see no obvious signs of damage when using the receiver, but I am still wondering if it potentially did some damage to the receiver that will manifest itself after a while? Do VU+ receivers have some kind a protection on the ethernet port?
