I upgraded to version 2.2.4 of CCA. After the upgrade CCA would not allow y SA540 to be part of my community in order to manage it. There is a message that says firmware version 1.1.42 or lower is not supported. This was working in CCA 2.2.2 and firmware version 1.1.42 is the latest for the SA540.
I am running a UC520 which is connected to an SA540.
