Lenovo 7XC7A03962 PCIe Riser Card

The Lenovo 7XC7A03962 is a PCIe riser card assembly created for the ThinkSystem SR950 server. By adding four x8 PCIe expansion slots, it lets administrators increase the number of high-speed peripherals the system can host without occupying extra rack space.

This riser connects directly to the SR950 system board, preserving signal integrity for network interface cards, storage controllers, or accelerator modules that demand consistent bandwidth. Its layout follows the server’s internal cooling path, so added cards receive proper airflow and the chassis maintains stable operating temperatures.

In environments where compute density and flexibility matter—such as virtualized data centers, high-performance computing clusters, or database servers that need more I/O—the card helps unlock additional connectivity without a chassis redesign. Teams can scale network throughput, attach specialized accelerators, or expand storage fabrics while keeping the existing SR950 infrastructure intact.

For IT staff aiming to extract more value and performance from a single server, the Lenovo 7XC7A03962 offers a straightforward path to growth with minimal installation effort and full compatibility assurance.

Highlights:

• Adds four x8 PCIe expansion slots to a ThinkSystem SR950 server
• Direct system board interface supports reliable, high-speed data paths
• Engineered for proper airflow alignment inside the SR950 chassis
• Ideal for network adapters, storage controllers, or accelerator cards
• Enables I/O expansion without increasing the server’s physical footprint
