Download the standalone firmware from below link, extract the R310 file from zip and upgrade the AP to standalone version.
https://support.ruckuswireless.com/software_downloads/1017-zoneflex-solo-access-point-104-0-0-0-1347... In order to upgrade, access the AP from a browser, if you hit the initial setup wizard of Unleashed, click on upgrade and use the image to upgrade to above version.
If facing any issues in upgrade, complete the Unleashed setup wizard and then go to Admin and Services >> Administer >> Upgrade >> Choose Local upgrade >> brows the R310 file extracted from zip and finish the upgrade.
Once upgrade is done, try pointing the AP to SZ as explained in my previous comment.
