Turn that access point to the back and make sure it is an IAP-305 and not an AP-305. An AP-305 looks the same, but requires a hardware controller.

Subject: IAP 305 won't join cluster
I have dealt with 205 and 305 and normally I configure a master AP and set a virtual controller. After than subsequent APs that are plugged into the network are automatically joined to the cluster and broadcast the same SSIDS as the master. Today I can see the 305 get an IP address. I get a refused connection if I try to access the GUI. The APs light flashed to confirm it was being factor reset so firmware shouldn't even matter. What could stop that AP from joining the cluster and is there any way to access its GUI? The only thing I can think of is using the IP address and making sure I'm adding port 4343.
