I have several versions of these POE adapters from different manufacturers for different voltage adapters. I had problems with EVERYONE else. Sometimes they show up, sometimes they don't, sometimes the LLDP discussion turns on the port on the switch but the output voltage doesn't. This particular ROCK is solid. This has worked on *every* switch I've tried it on (HP, Ubuquiti Edge, Mikrotik, Dell, and Netgear Prosafe have tried so far). I highly recommend this adapter.
