Lenovo 4X97A59807 SR650 V2 3.5 Middle BP Sas/sata CBL KIT

Lenovo 4X97A59807 SR650 V2 3.5-Inch Middle Backplane SAS/SATA Cable Kit

Overview

The Lenovo 4X97A59807 is a factory-new SAS/SATA cable kit designed for the 3.5-inch middle backplane configuration of the ThinkSystem SR650 V2 rack server. When expanding or reconfiguring drive bay wiring inside an SR650 V2 — whether adding a mid-backplane tray or replacing damaged signal cabling — this kit provides the correct manufacturer-specified cables to maintain signal integrity between the backplane and the system's storage controller. Using off-spec or generic cabling in SAS/SATA backplane paths risks link negotiation failures, intermittent drive dropouts, and voided support agreements; 4X97A59807 eliminates that exposure with genuine Lenovo interconnects matched to the SR650 V2 chassis design.

Compatibility

This kit is specific to the Lenovo ThinkSystem SR650 V2 platform in the 3.5-inch middle backplane configuration. It is not interchangeable with SR650 (Gen 1), SR650 V3, or other ThinkSystem rack models such as the SR630 V2 or SR850 V2 — backplane connector layouts and cable routing differ across generations and chassis sizes. If you are working with a rack server outside the SR650 V2 family, verify the correct cable kit part number against the Lenovo ServerProven compatibility matrix before ordering. The kit supports both SAS and SATA drive backplane connections, making it applicable to mixed-drive configurations within the supported chassis.

Installation Notes

Installation is an internal server maintenance operation requiring the SR650 V2 to be powered down and removed from the rack. Lenovo's server maintenance guidelines for this chassis require ESD precautions throughout. Cable routing inside the SR650 V2 chassis follows defined paths to avoid interference with airflow baffles and adjacent components — consult the SR650 V2 Hardware Maintenance Guide for the specific backplane routing diagrams before disconnecting or reconnecting any cables. No special tooling beyond standard server maintenance equipment is documented for this kit.
