5520 controller

[k.elnokrashy1]

I have a 5520 controller in Main office 
now we will open a new branch  with AP C9105A  and C9800-L-C-K9 

I need that all new access points to register in the 5520 controller and if the link is down they will register to the new one 

1- is C9105A can work on 5520 controller 
2- what do I need to configure that scenario 

thanks a lot

read the FAQ : (make sure you have right Code running to support new Cat 9K AP) 8.10.X

You need to setup redundancy config

As long as the 5520 is running 8.10.X.X.

Each AP is configured with the Primary Controller pointing to the 5520 and the Secondary Controller pointing to the 9800.

Just remember that there will be an outage when the APs fail over as they will need to reload to swap code versions.
