To Scooby_Doo, I'm sorry you feel we only have installation guides. Nothing could be further from the truth.
Firstly, all of our product documentation (hardware installation guides, software configuration and command-line guides, etc) are all found on the 'Documentation' tab of our support page (https://support.arubanetworks.com/Default.aspx?TabId=77). We don't put any of our guides behind a support login (as Ruckus does) which makes it far more efficient for our customers *and prospective customers* to find and read about our configurations and operations. For some reason, Ruckus feels the need to put most all of their documentation behind a support/paywall.
Secondly, we produce and publish, again on the public web and not behind a login, our Validated Reference Guides (http://community.arubanetworks.com/t5/tkb/v2/page/blog-id/Aruba-VRDs), which allows current and prospective customers (and obviously our competitors, which they have used and copied numerous times), on design specific grand deployments, operational strategies, etc.
Finally, we have a very robust and active AirHeads comunity where users like yourself can come with one-off questions for help.
In my experience, competitively building and testing our competitor's solutions, I have found our more liberal access to all documentation to be far above anyone else. Specific to Ruckus I had the hardest time because all of their docs were behind a suport login, so I had to really dig to find answers on their gear when configuring some of their mesh for testing.
So if you ever find that you can find the guides, come here and ask, and we can send you the correct link or get you the correct info. And in some cases (like your RAP-3 issue), sometimes TAC is the best answer.
