Hi
2240is likelly shipped with the old 7-mode OS and not cluster mode that the setup software should work with.
also it has 5 network cards on-board. you might be connected to a non-configured one.
if you can find a working ip address. try telnet or ssh to it. once you mange to login run "version"
if it's a 7-mode you can download and use "system manger" to mange it via a GUI.
