Lenovo 4X97A82939 SR650 V3 2.5INC Middle BP Sas/sata CBL KIT

Lenovo 4X97A82939 SR650 V3 2.5-Inch Middle Backplane SAS/SATA Cable Kit

Overview

The Lenovo 4X97A82939 is a factory-configured cable kit designed to complete the internal SAS/SATA signal path between the 2.5-inch middle drive backplane and the storage controller in the ThinkSystem SR650 V3 rack server. If you are expanding drive capacity in an SR650 V3 by populating the mid-bay backplane — or replacing a damaged signal cable — this kit provides the correct Lenovo-spec interconnects to restore full controller-to-backplane communication. Without the right cables in place, the controller will not detect backplane-connected drives, making this a mandatory installation component rather than an optional upgrade.

Compatibility

This cable kit is specific to the Lenovo ThinkSystem SR650 V3 and is matched to the 2.5-inch middle backplane (Mid BP) configuration. It supports both SAS and SATA drive connections, covering the dual-protocol backplane designs Lenovo uses in high-density SR650 V3 storage configurations. It is not interchangeable with SR650 V2 or SR630/SR550 backplane cables — backplane pinout and routing differ across generations, so confirm your chassis generation and backplane position (front vs. middle) before ordering.

Installation Notes

Route cables per the SR650 V3 maintenance manual cable-routing diagrams — mid-bay backplane paths are position-specific and must clear the airflow baffle. Secure connectors fully until the latch clicks; a partially seated SAS connector will cause intermittent drive detection errors that are difficult to diagnose. The kit ships at 10 lb, which reflects packaged weight including any protective packaging for the cable assembly.
