I apologize for that, the part number for the daughtercard is 99GTM  for the newest released card, and part 98493 for the previous version. Both are the X540's.
HI All, I'm looking on purchasing a X540-AT2 10 Gb  Intel daughter card. I want to keep costs down so will the daughter cards from a R720 work in an R730? I believe they look the same. If not can someone provide me with the part number?  Thanks, Nick
