We use hundreds of these in CX-4 cards. But not with the SFP+ Bob mentioned, we normally use breakout cables from the SN2100 switches.

Well at least ours are and all the documentation says the same. Presumably you have some sort of adaptor to make that work, could that be the issue? JAB. -- Jonathan A.
