I have been playing with this now for a while. I have decided on 1142 to deploy to my state office locations. NO PoE switches. I ordered the 1142 with the power pack and the AIR-PWRINJ3
Now the test. I plug the power directly into the AP and it powers up as expected.
I setup the power injector and verify the connection points and power up the supply. NOTHING happens. I swapped out the injector since I knew the power pack itself would power the AP. No good after 4 injectors.
I pulled a power injector for a 1252 and it powered the 1142 no problem.
what an I missing here. This is suppose to be a standard PoE power device.
