Trying to connect R700 and T301 to a ZD1200 controller? What version code on your ZD please?
Do APs connect but not get configured? Perhaps you need FW ports opened if APs and ZD are not local to each other.
See your ZD version User Guide, like this 9.13 GA example:https://support.ruckuswireless.com/documents/1106-zonedirector-9-13-ga-user-guide
and see FW ports that must be open for ZD/AP communications, starting on page 43.
