Lenovo 4X97A86431 SR655 V3 2.5IN M SAS CA KIT

Lenovo 4X97A86431 SR655 V3 2.5-Inch SAS Cable Kit

Overview

The Lenovo 4X97A86431 is a factory-matched SAS cable kit designed for the ThinkSystem SR655 V3 server platform, specifically supporting 2.5-inch drive bay configurations. If you're expanding or rebuilding drive backplane cabling in a dense SAS storage deployment, this kit provides the correct cable geometry and connector pinout for the SR655 V3 chassis — eliminating the guesswork of aftermarket substitutions that risk signal integrity on high-speed SAS links. The 4X97A86431 ships direct from Lenovo's supply chain (country of origin: MX), ensuring genuine connector tolerances and proper shielding rather than a third-party approximation.

Compatibility

Designed for the Lenovo ThinkSystem SR655 V3 rack server. This kit applies specifically to 2.5-inch drive bay SAS configurations on that platform. The SAS interface aligns with ThinkSystem-series enterprise storage components — do not install in SR645 V3 or SR635 V3 without confirming Lenovo's compatibility matrix, as chassis routing and backplane connector positions differ across V3 variants. If your SR655 V3 is configured for NVMe-only storage, this SAS cable kit does not apply — verify your backplane type before ordering.

Installation Notes

Route cables according to the SR655 V3 hardware maintenance guide — improper routing in the 2.5-inch bay zone can obstruct airflow and trigger thermal thresholds. SAS signal cables are sensitive to sharp bends; follow the chassis cable management arm and avoid pinching against drive carriers. Confirm backplane firmware compatibility with your installed RAID adapter before powering on after a cable replacement. This is a server internal cable accessory — no special tools are called out in the distribution data, but standard server disassembly (Torx T10 for most ThinkSystem panels) will be required to access the backplane.
