Can you explain a little more detail about what you mean?
by the way i tried the other port nothings change..
one of the 2 eth is/could be dedicated to iLo (check your manual for reference)..
in the past I had the same problem with a ML310: I plugged the cable in the wrong eth coukld not ping anywhere.
please post the result of
lspci -v | grep -i ethernet
and of
ifconfig
another question? is your server in server&gateway mode or server only?
