Which suggests PoE systems aren't all to one standard. I know they come in different speeds, and have suspected (haven't researched) whether different PoE adapters of the same rated speed are compatible. > > > Any disadvantage/corruption from running power over the Ethernet > cable? In addition, they can't be connected to surge suppressors, as the signal used over the power line is filtered by such. However, I have a pair of 200MBps PoEs at home, and it doesn't matter that they're connected to different circuit breakers. Though as I understand it, 85MBps PoE connections over different circuit breakers is slower than 10Mbps Ethernet.
