Are you following the procedure to on-board by Cambium ID as documented here http://community.cambiumnetworks.com/t5/cnMaestro/On-boarding-Prerequisites-and-Procedures-Part-1-of-4/m-p/51406/ ?
Note that for ePMP 1000 Hotspot you have to on-board by Cambium ID and not by serial number.
The dashboard page will display the status. What does it show in your case?
