Lenovo 4X97A97309 ST650 V3 M.2 Cable (B540I-2I)

Lenovo 4X97A97309 ST650 V3 M.2 Cable (B540I-2I)

Overview

The Lenovo 4X97A97309 is a factory-specific M.2 cable assembly designed for the ThinkSystem ST650 V3 tower server platform. If you're populating or reconfiguring M.2 storage in an ST650 V3 chassis — adding a boot drive, a cache device, or expanding NVMe capacity — this cable is the physical interface that makes it possible. The B540I-2I designation identifies the specific backplane connector pairing this cable serves; using the wrong cable risks misalignment, no-post conditions, or an unsupported storage configuration. Genuine part, factory-new.

Compatibility

Designed specifically for the Lenovo ThinkSystem ST650 V3 tower server. The B540I-2I callout refers to the integrated RAID/HBA adapter pairing on that platform. Confirm your ST650 V3 configuration includes the matching adapter before ordering — M.2 cable compatibility in ThinkSystem platforms is chassis-revision and adapter-specific. This cable is not a universal M.2 accessory; it is a platform-matched internal cable for this server family only. If you are working with a different ThinkSystem chassis or a different generation ST650, verify the correct cable option code in the server components selector before purchasing.

Installation Notes

Installation is performed inside the ST650 V3 chassis with the server powered down and depressurized per Lenovo service guidelines. Route the cable between the M.2 adapter slot and the B540I-2I controller interface per the ST650 V3 hardware maintenance manual — cable routing in dense tower platforms matters for airflow and for avoiding contact with rotating components. The cable assembly measures 9.60 × 5.90 × 2.20 in (packaged) and weighs 0.25 lb, consistent with a full internal cable kit rather than a bare single-connector wire. No special tooling is specified beyond standard server service procedures.
