how to install NVIDIA MCX623106AC-CDAT ConnectX-6 Dx EN Adapter Card 100GbE Crypto Enabled

  • Prepare the host system: Power down the server, unplug power, and open the chassis following the vendor’s safety guidelines. Confirm that you have a free PCIe x16 slot and adequate clearance for the tall bracket if you plan to use it.
  • Insert the card: Gently align the ConnectX-6 Dx card with the PCIe x16 slot and press evenly until the connector seats fully. Secure the card to the chassis with the appropriate screw to ensure stability and proper heat dissipation.
  • Physically connect any required cables: If your deployment requires external QSFP56 fiber or DAC cables, connect them to the dual-port QSFP56 interfaces according to your network design. Ensure cable lengths match your data-center topology.
  • Power on and enter the host’ BIOS/UEFI: Verify that the PCIe slot and memory topology are recognized. If Secure Boot or device-locking features are enabled, adjust BIOS settings accordingly to allow the NIC to initialize during POST.
  • Install drivers and software: Boot into the operating system and install the NVIDIA Networking drivers and management tools. Follow the on-screen prompts or official NVIDIA Networking installation guides to complete the driver package, including any required firmware updates for the MCX623106AC-CDAT.
  • Configure networking resources: Use the NVIDIA management utilities to assign interfaces, enable SR-IOV or virtualization features if needed, and configure encryption policies. Create and attach virtual networks, VXLANs, or NVGRE overlays as required by your cloud or data-center architecture.
  • Validate security features: Confirm hardware-accelerated crypto is active, verify Secure Boot status, and run security checks to ensure all protections are functioning before moving to production.
  • Test performance and stability: Run benchmark tests to verify throughput, latency, and CPU offload efficiency. Monitor temperatures and ensure fans or cooling solutions maintain safe operating temperatures under load.
  • Document the configuration: Record firmware versions, driver levels, channel assignments, and security settings for future audits and maintenance.
