AP1562I AP keeps disabling radios Using 3850UPOE

Hello,  I have a AIR-AP1562I-B-K9 that keeps turning the radio off and I believe it is power related but not sure why.  I am using a 3850 UPOE switch with 60w power capability. 

 

sh power inline on the switch shows the AP pulling 39.1 watts.

 

Bouncing the port will bring reboot the AP and it will come back online, radios on, etc.  But it will disable the radios again usually within an hour or so.  

 

From the WLC I am seeing the below

 

Attributes for Slot 0
Radio Type................................... RADIO_TYPE_80211n-2.4
Administrative State ........................ ADMIN_ENABLED
Operation State ............................. DOWN
Operation State Down Cause................... Radio reset due to (41) inline CDP low power mode holddown
Operation State Down Code.................... RADIO_RC_EXIT_LOW_PWR
Mesh Radio Role ............................. ACCESS
Radio Role .................................. Client Serving (Local)
CellId ...................................... 0

 

Any help would be greatly appreciated.  Thanks!

Hi,

Try setting the power statically to the port that is connected to this AP.

power inline static max xxxx

Thanks for the reply!  I have tried both "power inline static max 40000" as well as "power inline static max 50000".  Issue re-occurred both times.  I've also tried "power inline port 2x-mode" as well as disabled one of the radios so that only one is admin enabled.  Issue still occurs.  Any other suggestions?  

 

Thanks,

Re: AP1562I AP keeps disabling radios Using 3850UPOE

The last thing I tried was statically configuring the port for 60w and admin disabling one of the radios to try to conserve power.  Same issue.  Here is the show power inline detail for the switchport

Uhhhh ... what? 

Can you post the complete output to the following 3850 commands: 

sh power inline Gi 1/0/44
sh run interface Gi 1/0/44
sh version

^^^^^^^ The "power inline port 2x-mode" and "power inline static" have been added only since I started troubleshooting.  Originally the port was configured normally with no power inline commands.
