Keep getting the same error. This is new installation and doesn't have Service contract witch Cisco.

Hi Sandeep,

The radio issue was because of the PoE. I connected it to a PoE+ switch and both the radios came up. Thanks for your support.

Ajin.

Hi Sandeep,

If I am not wrong, the AP require 802.at PoE+, but I have connected it to 802.af PoE. May be that's why the radios are down. So I'll connect it to a PoE+ switch and update.

Thanks,

Or is it something to do with the certificate error? I read it somewhere and when I changed the time on the controller to a previous date, the error showing is different.

This is strange, it should use UDP port 5246 (not sure 5256 indicate actual port it use or it is cosmetic error)
