Lenovo 4X97B03871 SR650 V4 2.5IN BP3 NVME Cable KIT

Lenovo 4X97B03871 SR650 V4 2.5-Inch BP3 NVMe Cable Kit

Overview

The Lenovo 4X97B03871 is a NVMe cable kit designed for the ThinkSystem SR650 V4 server platform, specifically targeting the 2.5-inch BP3 (backplane 3) drive cage configuration. If you are expanding or reconfiguring NVMe storage in an SR650 V4 chassis, this kit provides the cabling infrastructure needed to connect the BP3 backplane to the system board or adapter — without sourcing individual cables that may not meet the routing or connector specifications Lenovo engineered for this enclosure. The 4X97B03871 is a factory-new, genuine component sourced through commercial distribution channels.

Compatibility

This kit is designed for the Lenovo ThinkSystem SR650 V4 server, BP3 (backplane 3) position, supporting 2.5-inch NVMe drive configurations. It is not interchangeable with SR650 V2 or V3 cable kits — backplane connector layouts and signal routing differ across generations. Confirm your chassis generation and backplane slot assignment (BP1, BP2, BP3) before ordering; the BP3 designation is specific to the third drive cage segment in the SR650 V4 bay map. For NVMe drive compatibility and server storage planning within the SR650 V4, cross-reference Lenovo's ServerProven configurator for validated drive and adapter pairings.

Installation Notes

NVMe cable routing in dense 2U platforms like the SR650 V4 is order-sensitive — install backplane cables before seating drives or adjacent adapters to avoid clearance conflicts. The NVMe interface means signal integrity is cable-length and connector-seating dependent; ensure connectors are fully seated and retention latches are engaged. Verify the target PCIe adapter or system board NVMe port is enabled in UEFI before powering on. No special tools are required beyond standard server maintenance practice, but anti-static precautions apply throughout. Weight of the kit as shipped is 10 lb including packaging.
