cisco air cap1602e e k9 not working with the wlan controller 2504-k9

Hi ,

we have some new cisco air cap1602e e k9 access points and they are not working with the wlan controller 2504-k9.

the controller is running ios Software Version 7.2.115.1 .looking at various blogs they  to upgrade our ios version but am wondering how to go about it .can you just upgrade to latest or is there a way to upgrade.

Below are the error messages from the AP.

Post the output to the following commands:

Product Version..............

Product Version.................................. 7.2.115.1

This is the firmware of your WLC.  Take note the version number. 

Product/Model Number                 : AIR-CAP1602E-E-K9

This is your AP model number.  

 

Go HERE.  Scroll down and you'll see that if you want to use 1600 then you'll need to upgrade the firmware of your WLC to 7.4.100.X.  

 

NOTE:  I would recommend you upgrade the firmware of your WLC to 7.4.121.0.
