Hi Michael,

You have to configure a SSID first, then you should be able to turn up the Radio/Radio's;

Changes to the Default Configuration-Radios Disabled and No Default SSID

In this release, the radio or radios are disabled by default, and there is no default SSID. You must create an SSID and enable the radio or radios before the access point will allow wireless associations from other devices. These changes to the default configuration improve the security of newly installed access points.

Hope this helps!
