Lenovo 4XH7A09866

Overview

The Lenovo 4XH7A09866 is a 1U G4 PCIe riser card designed to expand the capabilities of ThinkSystem servers by adding two x16 PCIe 4.0 slots with up to 32 lanes of bandwidth. This riser card enables the installation of high-speed network adapters, NVMe storage controllers, or specialized accelerators without requiring a larger chassis. It fits precisely in Lenovo 1U servers like the ThinkSystem SR630 V2 and SR645, maintaining optimal airflow and cable management thanks to its low-profile design and included mounting bracket.

Connectivity and compatibility

This riser card extends the server’s PCIe capabilities by providing two full x16 slots compliant with PCIe 4.0 standards, ensuring compatibility with a wide range of high-performance expansion cards. It fits directly into the riser bay of supported Lenovo 1U servers, allowing you to add network adapters, storage controllers, or accelerators that require high data throughput.

Installation and setup

Installation is straightforward with the included mounting bracket, designed to fit securely within the riser bay of compatible Lenovo servers. The low-profile design helps maintain proper airflow and cable organization, reducing the risk of overheating or clutter. This makes it a practical upgrade for data centers aiming to enhance server capabilities without downtime or complex modifications.

Ideal uses and environments

This riser card is well suited for data centers and enterprise environments where maximizing server expansion within a 1U chassis is critical. It supports virtualized workloads needing increased network throughput, database servers requiring additional storage controllers, and edge computing setups where rack space is limited. Its design balances performance and space efficiency, making it a strong choice for performance-driven server configurations.

We act solely as a reseller. Any product warranty is provided and administered by the manufacturer, not by our store. That means eligibility, coverage, and outcomes are determined by the manufacturer’s policy for each brand and model. Before purchasing, we recommend reviewing the warranty terms on the manufacturer’s website or in the product documentation to confirm what is covered and for how long.

If you need warranty service, please file the claim directly with the manufacturer. They may require proof of purchase, the product serial number, original packaging, photos, or basic troubleshooting. Some brands ask you to register the product or obtain a case number before shipping it for repair or replacement. We don’t submit or approve claims, but we can point you to the correct support links and contact details.

Keep your invoice and packaging in a safe place, and report any functional issues to the manufacturer as soon as they appear. If you’re unsure whether a problem is covered, the manufacturer’s support team can confirm next steps and timelines. While we cannot intervene in decisions or outcomes, we’re happy to provide purchase documentation or guidance so you can move through the warranty process smoothly.
