Lenovo 4XH7B03840 SR650/A V4 8X2.5IN Anybay BP Option KIT

Lenovo 4XH7B03840 SR650/A V4 8x2.5-Inch Anybay Backplane Option Kit

Overview

The Lenovo 4XH7B03840 is a factory-new backplane option kit designed to expand or configure the drive bay capacity of compatible ThinkSystem SR650 and SR650 V4 server platforms. This kit supports an 8x 2.5-inch Anybay backplane configuration — Anybay meaning the bays accept SAS, SATA, or NVMe drives interchangeably, giving you flexibility to mix storage tiers without a hardware swap. If you are planning a storage density build or retrofitting an existing SR650 chassis for NVMe acceleration, the 4XH7B03840 is the hardware starting point for that reconfiguration.

Compatibility

This option kit is specified for the Lenovo ThinkSystem SR650 and SR650 V4 (SR650/A) server platforms. The Anybay architecture is specific to the SR650 chassis family — do not assume cross-compatibility with other ThinkSystem models such as the SR630 or SR550 without verifying backplane bay geometry and connector pinout against those platforms' option compatibility matrices. Confirm your chassis generation and drive bay slot count before ordering; the V4 designation indicates a specific board revision that aligns with this kit.

Installation Notes

This kit weighs 10.00 lb, which is consistent with a fully assembled backplane bracket assembly rather than a bare PCB — handle accordingly during chassis installation. Country of origin is MX. Installation should follow the Lenovo ThinkSystem SR650 V4 maintenance documentation for backplane replacement procedures, including proper ESD precautions and torque specifications for drive cage mounting hardware. Consult the server storage accessories section for compatible drive and cable options that pair with this backplane configuration.
