1130AG Power problem

[Karlton Miller]

I have this AP and it has a problem.  If I plug in only the power injector with nothing plugged into the network side of the injector, nothing happens.  If I plug an ethernet cable from at Linksys POE switch to the network side nothing happens.  If I plug an ethernet cable from a Cisco 3560G POE switch to the network side of the power injector it powers fine. 

Once the AP is booted, I can pull the cable from the network side of the injector to the Cisco 3650 and the AP will continue to run.  Have tried multiple different pwrinj3 and AC adapter combination and nothing works.  I know it isn't the power injector that is the problem.  Something in the AP is not working correctly. 

Once the AP has been running for a while, if I unplug the power injector from the AP it will die, but if I plug it in again in less than 30 seconds the system will boot again just fine.  What is it about the 3560G that allows the AP to boot when nothing else will.

Any thoughts?

What if you connect the AP directly to a PoE switch (without power injector). does it work?

Have  you eliminated the cables thing? bad cables cause power problems usually. try to eliminate that part.

If all is fine and the AP is not working it could probably be an AP hardware (or maybe software) problem.

Yes it the AP works fine if you plug it in directly to our Cisco 3560 but it doesn't work if plugged into our Linksys Poe switch. Have tried different cables and the same symptoms.
