The Lenovo 4XH7A09866 is a 1U G4 PCIe riser card made for ThinkSystem servers that need more expansion room. Once seated in the riser bay, it presents an extra PCIe 4.0 path that carries up to 32 lanes of bandwidth and is arranged as two x16 connections. This added capacity lets you install a high-speed network adapter, an NVMe storage controller, or a specialized accelerator without moving to a larger chassis.
Engineered for a precise fit inside models such as the ThinkSystem SR630 V2 and SR645, the card follows a layout that is low profile so airflow stays clear and cables stay organized. A factory-supplied mounting bracket is included, allowing you to complete the upgrade with the standard tools already on hand in most data centers.
Whether you run virtualized workloads that suddenly need more network throughput, manage databases that call for additional storage controllers, or deploy edge solutions where every rack unit counts, this riser card delivers a clean and cost-effective path to greater flexibility.
