"PWR light is flashing green" indicates that AP is not getting IP address from the wired network.
Do you see any SSID/WLAN broadcasting? If yes, then it means Unleashed is configured but it is not able to reach rest of the internet and as well as the internet.
Could you connect a laptop on switch port where AP is connected and see if your laptop gets an IP address? If yes, then AP should also get the IP, if not then you may have to check where is the DHCP server and switch is configured correctly to provide DHCP.
If you think you cannot do it yourself then please open a case with Ruckus support.
