I can't find where it is documented as not supported(doesn't work) to use QSFP-H40G-CUxM DAC cable to connect the FEX to the 9K direct. The AOC cables work fine. The matrix simply states 40G direct is supported.
Regards.

Hi @Garry Cross
It is mentioned in the Nexus 2300 Data Sheet, that passive cables are not supported:

how far is the FEX? you can try connecting if ths is near to nexus it will give you any indication, nothing harm trying?
I use DAC cable for Fex and nexus it worked, i did not see any document about that for sure. (there may be but cisco documentation is too big).
