Lenovo 4X97A86427 SR655 V3 2.5IN BP3 NVME CA KIT

Lenovo 4X97A86427 SR655 V3 2.5-Inch Backplane 3 NVMe Cable Kit

Overview

The Lenovo 4X97A86427 is an NVMe cable kit designed for the ThinkSystem SR655 V3 server, specifically supporting the third 2.5-inch drive backplane position (BP3). When expanding NVMe storage capacity on an SR655 V3 — adding drives to a previously unwired backplane bay — this kit provides the signal cabling required to bring BP3 online. Without it, installed NVMe drives in that bay will not be recognized by the system, regardless of drive or controller availability. Weighing 10 lb, the kit ships from Lenovo's Mexico manufacturing facility and carries UNSPSC code 26121620.

Compatibility

This cable kit is specific to the Lenovo ThinkSystem SR655 V3 server platform. It is designed for the 2.5-inch drive backplane 3 (BP3) configuration and supports NVMe interface connectivity. It is not interchangeable with SR655 V2 or other SR-series backplane cable kits — Lenovo backplane cabling is generation- and position-specific. Verify your SR655 V3 chassis configuration and backplane slot assignment before ordering to confirm BP3 is the correct target backplane for your expansion.

Installation Notes

Route and seat all NVMe signal cables fully before powering the system — partial seating on NVMe signal connectors is a common cause of drive non-detection that does not always produce a clear error at POST. Confirm backplane power cabling is also in place; this kit covers signal only. Consult the SR655 V3 Hardware Maintenance Guide for connector pinout orientation and cable routing paths specific to the BP3 position.
