Hmm, we do not officially support an AP that was ZD or SZ managed, and then factory defaulted for "standalone mode",
customers should load the Solo AP images.
A SmartZone controller can convert ZD managed APs, due to an 'lwapp2scg' utility, but a ZD cannot recognize/convert
a previously SCG managed AP, unless it goes thru the Solo image.
That's creative the way you script the ZD connection info. Perhaps if you re-flashed the SZ managed APs with a Solo
image, they would join your local ZD. Here is a link to 18.104.22.168.1347 with both 7352 and R500 firmware.https://support.ruckuswireless.com/software/1017-zoneflex-solo-access-point-104-0-0-0-1347-ga-softwa...
You can direct APs to a ZD or SZ with DHCP option 43 too, using sub-option 03 for ZD or 06 for SZ controllers.https://support.ruckuswireless.com/answers/000002022
