New Cisco AP Fails to Join Controller

Field Notice: FN - 70479 - Out-Of-The-Box AP Fails to Join Controller or Joins with Single Radio Due to Country Mismatch - Replace on Failure

https//www.cisco.com/c/en/us/support/docs/field-notices/704/fn70479.html



A newly installed Access Point (AP) fails to join its controller or it joins the controller, but is only able to bring up one radio due to a manufacturing mismatch between the AP's domain and the radio's domain.

On a Mobility Express (ME) AP, the 2.4GHz radio will come up in Day 0 mode; however, after you configure the correct country code, the internal AP might fail to rejoin or might bring up only one radio.
