I have recently purchased 3 of these APs.  I unboxed the first, and was able to see it drawing power from the switch.  I Then saw it request an IP address for itself. I can not open any web interface at this address.  I ran an NMAP from the same segment, and see 2 ports open.  44443 and 10000.  that's it.  neither are the webinterface. To note, I have 3 Omada EAP 655s as well and they work perfectly in standalone mode. 

Additionally, I factory reset the FESTA using the pinhole method.  After a boot, the same thing, 2 ssids with no password are available, and I can connect to either of those,
