If we can get the /tmp/anaconda.log or output of tty3(you can send 
Ctrl+Alt+F3 to see the output),just search for "switching from media",if 
find this word,it's the time for swap CD.But get the /tmp/anaconda.log 
in non-network environment is a challenge,we still have no answer. As 
James mentioned above, we can use minimon script to do this in network 
environment.

Thanks
