I'm using an Aerohive AP
Wait, does that device even support powering using Passive POE? I can see it supporting active POE over mode A, not passive/mode B.
Maybe it does but only using 100Mbit but can't find anything about it being officially supported for your device.
There is a difference between mode A and mode B POE, they use different cables and can cause different connection speeds if mixed incorrectly. Worst case they fry equipment! For more information about the differences, I wrote a bit about there here
a while back.
