I am trying to connect my PXIe-1095 to a Switch (SN2100). I am successfully able to use a DAC 40G copper cable, but when I switch the cable to a QSFP-CSR-40G cable, the PXIe-8240 no longer recognizes it. I looked at the known problems on the Intel-710 card (in the 8240), and saw that I have to disable auto-negotation on the switch which I did. However, I still am not having any success.
Has anyone encountered this issue or have any idea how to resolve this?
Thanks
