It looks like the ethernet is not connecting.  Are you sure that these 3 
ethernet cards are gigabit ethernet?  Are they active?  Have you done an 
ifconfig on them to turn them on?  Can you make a regular network 
connection to another device with them?  What models are they, and what 
kernel modules do they use?

This is the correct behavior.  The ethernet LED should come back on when 
the ethernet connection is made.

Yes, that is the version number.
