Lenovo 4X97B05127 Thinksystem ST650 V3 Signal Cable for RAID 4450/5450/9450-8/16I 8GB Adapter to 8

Lenovo 4X97B05127 ThinkSystem ST650 V3 RAID Adapter Signal Cable

Overview

The Lenovo 4X97B05127 is a factory-specific signal cable engineered for the ThinkSystem ST650 V3 server, providing the internal data path between supported RAID adapters and the storage backplane. If you are replacing a failed cable or completing a drive-bay expansion inside an ST650 V3 chassis, this is the cable that restores the connection — third-party substitutes risk incompatibility with Lenovo's validated storage stack and may prevent RAID controllers from initializing correctly.

Compatibility

Designed for the Lenovo ThinkSystem ST650 V3 server platform. Compatible with the following RAID adapters: ThinkSystem RAID 4450-8i, RAID 5450-8i, RAID 5450-16i, RAID 9450-8i, and RAID 9450-16i — all with 8GB cache. This cable is specific to the ST650 V3 chassis bay configuration; it is not interchangeable with signal cables for ST650 V2 or other ThinkSystem tower and rack models. Verify your server generation and the exact adapter part number before ordering.

Installation Notes

Sourced from MX (country of origin) as a genuine Lenovo component — factory-new with no grey-market or parallel-import risk. Route according to Lenovo's ST650 V3 server maintenance documentation for cable management inside the chassis; improper routing in dense storage configurations can impede airflow and trigger thermal alerts. Confirm the RAID adapter is seated and the server is powered down before seating or removing this cable. The UNSPSC classification 26121620 identifies this as a signal/data cable assembly, not a power cable — do not substitute for backplane power connections.
