    Mellanox 40 GbE and Dell Powerconnect 8164

      Hey guys,


      are you aware of any problems with ConnectX3 (using the latest drivers) and Dell Powerconnect 8164 (firmware switches when using Mellanox QSFP passive copper cables (part number MC2210126-005)?


      We're getting a link up event for a few seconds and then the link goes down and stays down when using these cables.

      With different cables from Dell, the link stays up. The mellanox cable itself works when connecting the NIC to another mellanox NIC.


      Dell blames the cables for not being tested with their switch and is unable to provide any further help.


      Does anybody use the same configuration or knows similar problems?
