We have 6 N7 chassis with platinum/diamond DFE blades, and they work great. We also have a slew of the C2 and A2 stackables, and they also seem to be pretty solid. If you go for it, check out the Netsight software suite, as I believe it is an essential tool to fully utilize their platforms (Console, Policy Mgr, and Inventory Mgr is what I use). We also use their RoamAbout wireless system, which works well enough, but I feel that the HighPath system by Siemens (which Enterasys now owns a division of) is a better solution.
BTW, the company I work for was also a Cabletron customer for years...
If you would like more info, just pm me.
Cheers!
