Time Capsule not shown in Server App

Hi Community

I installed ML on my Mac Mini and configured all necessary services - it seems to work fine!

Now I wanted to configure Radius Logon via WLan. In my environment I have a Time Capsule (1GB) and a Airport Extreme. The Airport Extreme is connected to the Internet on first floor. The Server is also located in the 1st floor and connected with Lan cable (wired). The Time Capsule is also connected wit Lan cable to the Same Hub where Server and AP Extreme are connected. In my server App I can see the AP Extreme and can successfully activate Radius Logon. But I can't see my TC and so I' unable to activate Radius.

Is there anything I have to configure also on the Tc?
