Cisco AP POE shut down

[alalem2010]

hello guys

i have faced a worrying problem , i have connect a new "AIR-AP3802P-E-K9" to controller , i have saw the state of AP in controller "downloading"  after that there is no response , then i unplugged  the Ethernet cable  (POE) , suddenly there is no more POE work , the switch is OK but the problem in AP, is it hardware  or SW problem ??.

If you've swapped patch cables and the AP still doesn't light up then it is, most likely, dead.

Any solutions , i unplug the patch cable after a long time and the downloading state disappear , and also the AP disappear from controlle's AP list

What is the switch? Have you confirm if the switch complies with the PoE requirements of the 3800?

[alalem2010]

the switch is 3850 and it is working well with other APs

Have you issue the command "show power inline" to confirm that you have enough power to all the APs?
