how to install SFN8522-PLUS

• Power down the server and unplug it from the power source to ensure safety during installation.
• Open the server chassis and identify an appropriate PCIe expansion slot with sufficient bandwidth (typically a PCIe Gen3 x8 or x16 slot, depending on the system and card design).
• Insert the SFN8522-PLUS into the selected PCIe slot firmly until it is seated and the retention mechanism engages.
• Secure the card with a mounting screw or retention bracket as required by your chassis to prevent movement during operation.
• Install SFP+ modules or connect optical/fiber media as needed for your network topology; ensure appropriate cabling and SFP+ transceivers are in place.
• Power on the server and boot into the operating system. Install the necessary drivers and Onload software packages that enable the card’s accelerated sockets and time synchronization features.
• Verify link status for both ports in the OS and configure any required network settings, such as VLANs, MTU, and bonding/teaming if you plan to use multiple interfaces for redundancy or load balancing.
• Enable PPS/PTP time synchronization in the OS or orchestration tooling as needed, and validate time distribution across servers with test timestamps and synchronization checks.
• Perform a basic throughput and latency test to confirm the expected performance characteristics and to validate driver and Onload integration.

Frequently asked questions

• What is the SFN8522-PLUS best suited for? It is engineered for data centers and latency-sensitive environments requiring high-speed 10GbE networking, low CPU overhead, and precise time synchronization across servers. It is ideal for virtualization, storage networks, high-performance databases, analytics workloads, and real-time processing.
• Does the SFN8522-PLUS support Onload acceleration? Yes. The PLUS variant includes Onload-accelerated sockets to reduce CPU utilization and minimize network latency, delivering faster application response times.
