We are wondering if anyone has had any luck with powering an IP55 version of the MAX-BR1-LTE’s instead of the power injector ? We have tried a few different models we had around here with no luck. They are AF/AT and PoE+ with none of them having any luck. We tried with cisco 3750-48PS-E, dell 6248P, and poe plus HP J9146A , all of which have no luck powering the units. We are wondering if any one else has had luck powering these with a PoE switch, if its possible, and if so, what models they used to accomplish this?
