I tried connecting using a different still the result is same. Does anyone know on how to configure the Mellanox cards “Active” state and Physical state “Enabled”? If need any additional info, please let me know. ---

Hello This might point to a physical issue, with the cable itself. Please try to use a different cable, one that you’re sure works on different setups, and see if that solves the issue. If not, please open a case at [enterprisesupport@nvidia.com](mailto:enterprisesupport@nvidia.com) and it will be handled according to entitlement. Thanks, Jonathan.
