Lenovo 4X97B03874 SR650 V4 2.5IN Rear NVME Cable KIT

Lenovo 4X97B03874 SR650 V4 2.5-Inch Rear NVMe Cable Kit

Overview

The Lenovo 4X97B03874 is a rear NVMe cable kit designed to complete the drive backplane wiring in ThinkSystem SR650 V4 servers configured with 2.5-inch rear NVMe storage bays. When a server is ordered or expanded to support rear-facing NVMe drives, this cable kit supplies the internal signal routing between the rear drive backplane and the system board — without it, installed rear NVMe drives will not be recognized by the host. Part number 4X97B03874 is the factory-specified assembly for this configuration; using a generic or substitute cable assembly risks signal integrity issues and will typically void Lenovo's system warranty on that component path.

Compatibility

This kit is designed for the Lenovo ThinkSystem SR650 V4 platform in 2.5-inch rear NVMe drive configurations. It is specific to that chassis generation — it is not interchangeable with SR650 V3, SR650 (original), or any other ThinkSystem rack server series. Before ordering, confirm your SR650 V4 chassis is configured or intended to support rear NVMe bays; not all SR650 V4 build-outs include a rear drive cage, and the cable kit serves no function without the matching rear backplane assembly installed. If you are populating a server storage expansion or adding NVMe capacity post-deployment, verify the rear cage option is physically present in the chassis first.

Installation Notes

Installation is an internal server cable replacement — the server must be fully powered down and racked safety precautions observed before opening the chassis. Route the cable per Lenovo's SR650 V4 hardware maintenance guide; the connector keying prevents reversal but incorrect seating will result in the drive bay reporting absent. Country of origin is Mexico. Shipping weight is 10 lb including packaging.
