Zoltan,
The Web Specialist can be used with an https interface, and a physical console 
to the 3584 is available. I have little experience with the physical console, 
but you could determine whether it has the features and suits your needs better 
than the Web Specialist.

Wanda just wrote the Red Book on setting up a 3584. It's more complete, easier 
to comprehend and better organized than anything you will find in the official 
documentation. 

With best wishes to all,
