Lenovo 4X97A59812 SR650 V2 2.5 Front BP3 NVME Cable KIT

Lenovo 4X97A59812 SR650 V2 2.5" Front BP3 NVMe Cable Kit

Overview

The Lenovo 4X97A59812 is a Lenovo factory-matched NVMe cable kit designed for the ThinkSystem SR650 V2 server's 2.5" Front Backplane 3 (BP3) configuration. If you're expanding or replacing the NVMe signal cabling in an SR650 V2 chassis — during a drive backplane swap, a failed cable replacement, or a storage density upgrade — this kit provides the correct connectors and routing for that specific backplane position without improvising with generic cables that may not physically route or seat properly in the chassis.

Compatibility

This cable kit is purpose-built for the Lenovo ThinkSystem SR650 V2 (7Z73) with the 2.5-inch drive server storage components Front Backplane 3 (BP3) NVMe configuration. It is not a universal NVMe cable — the connector pinout, cable length, and retention clips are engineered for this chassis and backplane position. Using it in SR650 (V1), SR650 V3, or any other ThinkSystem platform is not supported by this part number. Verify your server's backplane map (available in the SR650 V2 Lenovo ThinkSystem hardware maintenance manual) before ordering to confirm BP3 is the correct backplane position for your drive bay layout.

Installation Notes

Replacement or installation requires powering down the server and following Lenovo's ESD precautions — NVMe signal cables are sensitive to static discharge. Route cables per the SR650 V2 cable routing diagrams; incorrect routing in a 2U chassis can obstruct airflow and trigger thermal alerts. The kit weighs 3.65 lb and measures 16.40 × 11.80 × 3.20 inches in packaging — plan bench space accordingly for a rack server cable swap procedure.
