Lenovo 4XH7A82915 SR650 V3 Midele 8X2.5INC NVME BP KIT

Lenovo 4XH7A82915 SR650 V3 Midplane 8x2.5" NVMe Backplane Kit

Overview

The Lenovo 4XH7A82915 is a midplane backplane kit that adds an eight-bay, 2.5-inch NVMe drive cage to ThinkSystem SR650 V3 rack servers. If your SR650 V3 is running short on NVMe storage density — common in surveillance NVR workloads, edge AI inference nodes, or high-throughput database tiers — this kit expands native NVMe capacity without requiring an external enclosure or a separate HBA card. At 10 lb, the assembly is a substantial mechanical component designed for tool-assisted installation inside the SR650 V3 chassis.

Compatibility

The 4XH7A82915 is designed specifically for the Lenovo ThinkSystem SR650 V3. It is not a universal backplane — do not attempt to fit it in SR650 (Gen 2 or earlier), SR630, or other ThinkSystem rack server families. The NVMe interface means drives installed in this backplane connect via PCIe lanes directly, bypassing SAS/SATA controllers — so your SR650 V3 must have available PCIe bandwidth or a supported NVMe switch/retimer configuration to populate all eight bays. Confirm your SR650 V3's configured riser and processor lane allocation before ordering if you plan to populate all bays simultaneously. Country of origin is Mexico (MX); UNSPSC code 43211600 (computer storage devices and media).

Installation Notes

This is a mechanical backplane kit requiring chassis disassembly. Installation should follow Lenovo's SR650 V3 hardware maintenance guide for the midplane bay — improper seating of the NVMe signal connectors can result in drives not being recognized at POST. The 10 lb weight indicates this is a full cage assembly, not a bare board; handle with care to avoid flex damage to the PCIe edge connectors during installation. Antistatic precautions are mandatory. No tools or drive media are included — drives and any required NVMe cables must be sourced separately based on your SR650 V3's cable routing kit configuration.
