When an autonomous AP521 access point is converted to controller-mode operation using the CCA, the 
access point properties screen continues to indicate that the access point is an AIR-AP521G-A-K9 after 
the conversion. This is in agreement with the product label on the access point. However, the CCA 
displays a small triangle icon next to the converted access point to indicate that the access point is now 
operating as a controller-mode access point.  

The CCA conversion process is one-way. Once the conversion takes place, you cannot restore the access 
point to autonmous operation.
