Intel ME, AMT, MEBX

I think I have the intel remote management but I know nothing about it. When setting it up with a staic IP for example and the mother board has 2 onboard Nics which one would the intel remote management be using?

I ask as I have ESXI only picking up one of the onbaord NIC's and I have asked about that in a different thread here http://community.spiceworks.com/topic/369002-esxi-5-1-only-picking-up-one-nic
