Access point is down due to POE issue , getting 30 watts instead of 40 watts

[teja]

Hi fellow meraki users , 

i have a access point connected to our switch and it went down , by checking power inline status , it is showing as IEEEPD and also other access points are getting 40 watt power and this one is getting 30 watt power.
Cisco Meraki cw91661  is connected to Te1/0/20 , Could someone let us know what is the exact issue and why AP went down.

If the device is only receiving 30W, it may not be receiving enough power for optimal operation.

I suggest you open a support case.

To which platform AP is connected ? i would suggest checking power on the switch if it has enough power for AP

[BlakeRichardson]

Does the switch have enough POE capacity to support all of the devices plugged into it?
