How to install Solarflare XtremeScale X2541

• Power down the server and disconnect all cables before handling the system slot and the NIC to prevent static discharge and equipment damage.
• Identify an appropriate PCIe slot that matches the card’s interface requirements and is compatible with your server’s motherboard and expansion policies.
• Insert the X2541 card firmly into the PCIe slot, ensuring proper seating and alignment, then secure the card with the appropriate bracket screw to prevent movement during operation.
• Reconnect power and network cables, then boot the server and enter the operating system setup to begin driver installation.
• Install the latest drivers and Onload software provided by the vendor, following the platform-specific instructions for Linux or Windows to enable hardware acceleration and network offloads.
• Configure the NIC within the operating system or via your virtualization/orchestration stack, enable SR-IOV if required, and apply any QoS or traffic-shaping policies to ensure predictable performance for latency-sensitive workloads.
• Verify the network interface detects correctly, negotiate the proper speeds (up to 100G), and perform basic latency and throughput tests to confirm the adapter is operating as expected.
