Lenovo 4X97A87901 SR635 V3 M.2 X4 Sata/nvme CA KIT

Lenovo 4X97A87901 M.2 x4 SATA/NVMe Carrier Kit

Overview

The Lenovo 4X97A87901 is an M.2 carrier adapter kit designed to add M.2 form factor storage expansion to compatible Lenovo ThinkSystem server platforms. Supporting both SATA and NVMe interface protocols via an x4 connection, this kit lets you deploy fast M.2 SSDs — either SATA-based drives for cost-effective boot or log workloads, or NVMe drives where latency and throughput matter — without being locked into a single storage protocol. This is a factory-new, genuine Lenovo option kit, not a third-party adapter.

Compatibility

The 4X97A87901 is designated for the Lenovo ThinkSystem SR635 V3 server platform. If you are deploying M.2 storage in an SR635 V3 and need to verify drive compatibility for your specific workload, cross-reference the Lenovo ServerProven compatibility list for supported M.2 SATA and NVMe SSD options before ordering drives separately. This kit does not include an M.2 drive — it is the carrier and cabling infrastructure only.

Installation Notes

Manufactured in Mexico (country of origin: MX). Classified under UNSPSC code 43211502 (computer storage devices and accessories). Installation is performed inside the SR635 V3 chassis; consult the Lenovo ThinkSystem SR635 V3 Maintenance Manual for slot assignment, torque specifications, and firmware prerequisites before committing a drive type — SATA and NVMe M.2 slots may not be interchangeable depending on system configuration. Verify your server's current riser and backplane configuration supports this kit prior to installation.
