Lenovo 4X97A86423 SR655 V3 2.5IN BP1 NVME CA KIT

Lenovo 4X97A86423 SR655 V3 2.5-Inch NVMe Backplane Cable Kit

Overview

The Lenovo 4X97A86423 is a backplane cable kit designed to extend NVMe drive connectivity within the ThinkSystem SR655 V3 server platform. When expanding storage capacity or replacing a damaged cable assembly in a 2.5-inch bay configuration, this kit provides the correct NVMe-rated interconnect between the drive backplane and the system board — keeping your storage fabric running at full PCIe bandwidth rather than falling back to a mismatched or improvised cable. The 4X97A86423 is the field-replacement and configuration-expansion part for this specific bay and backplane combination.

Compatibility

Designed for the Lenovo ThinkSystem SR655 V3 rack server using the 2.5-inch Bay Backplane 1 (BP1) NVMe configuration. Confirm your server's backplane slot assignment and bay position before ordering — the SR655 V3 supports multiple backplane configurations, and cable kits are not interchangeable across backplane positions or drive form factors. This kit is specific to the 2.5-inch NVMe backplane; do not use with SAS/SATA backplane variants or the 3.5-inch bay configurations available on the same platform. For servers in a high-density storage or AI compute role where NVMe throughput directly affects workload performance, verifying the correct cable assembly before installation prevents downtime during drive population or reconfiguration.

Installation Notes

Cable routing inside the SR655 V3 chassis follows Lenovo's prescribed management paths — consult the server's Hardware Maintenance Guide for backplane cable routing diagrams specific to your chassis revision before installing. Seat all NVMe cable connectors fully and verify latch engagement; a partially seated NVMe connector will result in drive non-detection without a clear error at POST. Ensure the system is powered off and ESD precautions are observed prior to handling. No special tooling is documented in available evidence beyond standard server hand tools.
