Lenovo 4X97A82931 SR650 V3 3.5INC Middle BP Sas/sata CBL KIT

Lenovo 4X97A82931 SR650 V3 3.5-Inch Middle Backplane SAS/SATA Cable Kit

Overview

The Lenovo 4X97A82931 is a factory-new SAS/SATA cable kit designed for the 3.5-inch middle backplane configuration of the ThinkSystem SR650 V3 server. When expanding storage or replacing damaged internal cabling on an SR650 V3 build, this kit provides the correct OEM-spec cables for routing signals between the middle backplane and the RAID/HBA adapter — eliminating compatibility guesswork and ensuring signal integrity at the connector level. At 10 lb, the kit ships with the wiring needed for a full middle backplane installation rather than a single cable swap.

Compatibility

Designed specifically for the Lenovo ThinkSystem SR650 V3 (7D75, 7D76, 7D77 series) configured with the 3.5-inch middle backplane option. This cable kit supports both SAS and SATA drive interfaces, covering mixed-drive deployments where SAS HDDs and SATA drives share the same backplane. It is not cross-compatible with the SR650 Gen 2, SR650 V2, or front/rear backplane variants — confirm your SR650 V3 backplane position (front, middle, or rear) and drive form factor (2.5-inch vs. 3.5-inch) before ordering. For server storage accessories, matching the exact backplane position and chassis generation is critical: Lenovo's option kit numbering differentiates these explicitly and substitutions will not seat correctly.

Installation Notes

Installation targets the middle backplane bay of the SR650 V3 chassis. Route cables per the SR650 V3 data center infrastructure maintenance manual — Lenovo documents specific cable-routing channels and tie-down points to avoid interference with airflow baffles and adjacent drive cages. Verify the RAID controller or HBA installed in the system supports the SAS/SATA port count required by the middle backplane before commissioning.
