Lenovo 4X97A93808 Thinksystem SR650 V3/SR655 V3 M.2 RAID B540I-2I Sata/nvme Cable KIT

Lenovo 4X97A93808 ThinkSystem M.2 RAID B540I-2I SATA/NVMe Cable Kit

Overview

The Lenovo 4X97A93808 is the factory-matched cable kit for the B540I-2I M.2 RAID adapter in Lenovo ThinkSystem SR650 V3 and SR655 V3 rack servers. If you are expanding or replacing internal M.2 storage paths — whether deploying SATA or NVMe M.2 drives for OS boot, caching, or edge workloads — this kit supplies the correct interconnect between the B540I-2I RAID controller and the M.2 slots. Using the wrong cable risks signal integrity issues or outright incompatibility; the 4X97A93808 is the manufacturer-designated component for this controller pairing, eliminating that guesswork.

Compatibility

Designed specifically for the following Lenovo ThinkSystem rack server platforms:

• Lenovo ThinkSystem SR650 V3 — 2U dual-socket server, paired with the B540I-2I M.2 RAID adapter
• Lenovo ThinkSystem SR655 V3 — 2U single-socket AMD EPYC server, paired with the B540I-2I M.2 RAID adapter

Supports both NVMe and SATA M.2 interface types — so whether your M.2 drives are NVMe (PCIe-attached, higher throughput for latency-sensitive workloads) or SATA (lower cost, adequate for boot/logging), this single kit covers both paths. Do not substitute generic M.2 cables; connector keying and routing geometry are chassis-specific on V3 platforms.

Installation Notes

This kit is a Form Factor M.2 internal cable assembly — installation is performed during server configuration or field upgrade of the B540I-2I adapter. Confirm the B540I-2I RAID card is already seated before routing these cables. Lenovo V3 chassis use managed cable routing; follow the service guide's cable-path diagrams to avoid pinch points near drive backplanes. No special tooling beyond standard ESD precautions and a Torx driver set (for panel removal) is required. Weight of the kit as shipped is 7.00 lb including packaging.
