Lenovo 4X97A90294 ThinkSystem SR665 V3 2.5" Front BP2 NVMe Gen5 Performance Cable Kit

Overview

The Lenovo 4X97A90294 is a factory-matched NVMe Gen5 cable option kit designed specifically for the 2.5" chassis front backplane 2 (BP2) position in the ThinkSystem SR665 V3 server. If you're expanding NVMe Gen5 drive capacity on an SR665 V3 and need to wire the second front backplane segment, this is the cable set that closes the loop between the backplane and the platform's PCIe Gen5 controllers — without improvising with incompatible or lower-generation cabling that would bottleneck NVMe Gen5 throughput. The 4X97A90294 ships as a Lenovo-sourced option kit, ensuring signal integrity and mechanical fit are validated for this specific chassis configuration. Weighing 2.0 lb, the kit is compact and self-contained for installation into the SR665 V3 bay.

Compatibility

This cable kit is compatible exclusively with the Lenovo ThinkSystem SR665 V3 configured with a 2.5" small-form-factor chassis. It targets the front BP2 (second backplane) NVMe Gen5 drive segment. It is not interchangeable with SR665 V2 or earlier SR665 variants, which use different backplane connectors and PCIe generations. It is also not applicable to the 3.5" LFF chassis variant of the SR665 V3, which uses a different front backplane layout. If you are populating only BP1 (the first front backplane), this kit is not required. Confirm your SR665 V3 chassis SKU and backplane configuration in Lenovo's ServerProven or the system's hardware maintenance manual before ordering. For the broader server storage and infrastructure accessory catalog, verify BP2 slot population matches your drive count and controller pairing.
