Can RAP-2WG be configured without Aruba Master Controller?

I found some RAP-2WG used previously for remote VOIP setup. I've hard-reset them to factory defaults and following this procedure I can access the console http://rapconsole.arubanetworks.com/ and I see they are running ArubaOS Version 3.3.2.11-rn-3.0.1.

Upon entering it asks me for an Aruba Master Controller IP or host. Can these devices be configured without it (which I don't have anymore) or are they basically useless without one?

Thanks!
