Console into the AP and reboot the AP.

Post the entire boot-up process.

- Check ap-model , versus controller-model constraints with :

I checked the software it is compatible with the AP model, any other suggestion ?

I am far from the AP, will let you know once I can get the boot process.

- You will need the output from the complete boot process as Leo suggested,
