Lenovo 4XH7B03841 SR650/A V4 8X2.5NVME BP Option KIT

Lenovo 4XH7B03841 SR650/A V4 8x2.5" NVMe Backplane Option Kit

Overview

The Lenovo 4XH7B03841 is a factory-new backplane option kit designed to expand NVMe drive capacity in ThinkSystem SR650 and SR650 V4 servers. This kit adds an 8-bay 2.5-inch NVMe backplane, giving storage architects a direct path to increase all-flash NVMe density in an existing SR650/A V4 chassis without a full system replacement. If your workload is pushing I/O limits on a current SR650 deployment and you need more NVMe slots rather than a new server, this is the targeted hardware addition that makes it possible.

Compatibility

The 4XH7B03841 is engineered specifically for the Lenovo ThinkSystem SR650 and SR650 V4 (SR650/A V4) server platforms. It is not a universal backplane — fit is chassis-specific, and installation requires a compatible SR650/A V4 system with an available backplane bay. Before ordering, confirm your server's current backplane configuration and available expansion slots against Lenovo's SR650 V4 configuration guide to avoid conflicts with existing drive cages or cable routing. This kit does not apply to SR630, SR550, SR850, or other ThinkSystem models outside the SR650/A V4 family.

Installation Notes

At 10 lb, the 4XH7B03841 is a substantial hardware option — plan for two-person handling during chassis installation to avoid damage to the backplane connector. Country of origin is Mexico. Installation should follow Lenovo's SR650 V4 hardware maintenance guide; backplane connector alignment and cable management are the primary fitment concerns. No special tooling beyond standard server maintenance equipment is specified in available documentation.
