Release 4.2.176.51M does not support Cisco 1520 (1522, 1524) series mesh access points. 
Cisco 1520 series mesh access points are supported in release 5.2 (and later) of the controller 
mainline release.

Enterprise mesh is not supported in 4.2.176.51M.

The 1250 series access point have a hardware limitation where beacons can only be output 
at intervals that are multiples of 17 milliseconds. When these APs are configured for a 
100-millisecond beacon interval, they transmit beacons every 102 milliseconds. Similarly, 
when the beacon interval is configured for 20 millsieconds, these APs transmit beacons 
every 17 milliseconds.
