I know there are firmware updates beyond 5.1.7 for my NMC2 cards, but struxureware data center expert isn't downloading them, and obtaining the firmware file and applying it to my server doesn't make a difference, either. I've noticed this with both 7.2.4 and 7.2.5...is this a bug, or is this feature no longer a supported means of upgrading firmware, or, is the fact I'm below 6.0.x on my nmc2s the reason they aren't recognized as needing/having a firmware update? I'm not looking to update just yet (experiments with one card have revealed bugs I'm not comfortable with) but having the option to use my server for the process would be nice when I'm ready to move forward.

I think that they need to upgrade the firmware catalog. When you say "obtaining the firmware file and applying it to my server" - what file did you mean specifically? The firmware .exe or the firmware catalog?
