Lenovo 4X97A82937 SR650 V3 Front Backplane SAS/SATA Cable Kit

Overview

The Lenovo 4X97A82937 is a SAS/SATA cable kit designed specifically for the front drive backplane 3 (BP3) position on the ThinkSystem SR650 V3 server, supporting 2.5-inch drive configurations. When you're expanding storage or replacing damaged signal cables in a populated SR650 V3 chassis, this kit provides the exact factory-specified cable harness for BP3 — keeping drive signaling clean and avoiding improvised substitutions that introduce compatibility risk. At 2.00 lb, the kit is appropriately sized for the multiple cable runs a front backplane connection requires. The 4X97A82937 supports both SAS and SATA drive protocols, meaning it works whether your BP3 is populated with SAS HDDs, SATA HDDs, or SATA SSDs — no separate cable variant needed per drive type.

Compatibility

This cable kit is specified for the Lenovo ThinkSystem SR650 V3 2U rack server with a 2.5-inch front drive configuration. It targets the BP3 (third front backplane) position specifically — not BP1 or BP2. Verify your SR650 V3 chassis configuration and backplane layout before ordering: the SR650 V3 supports multiple front-bay configurations depending on the ordered drive cage topology, and BP3 is only present in higher-density drive count builds. If your system uses only BP1 and BP2, this kit is not the correct part. Consult the SR650 V3 server storage configuration guide to confirm your backplane map before purchase.

Installation Notes

Route and seat each connector fully before powering the system — partial seating on SAS/SATA backplane connectors is a common source of drive non-detection that can be misdiagnosed as a drive or controller fault. Observe static-discharge precautions throughout. Replacement should be performed with the system powered down and PSU cables disconnected. No special tooling is indicated beyond standard server servicing equipment.
