Lenovo 4X97B03865 SR650 V4 Rear SAS Cable Kit

Overview

The Lenovo 4X97B03865 is a rear SAS cable kit designed to support eight 3.5-inch drive bays in the SR650 V4 server platform. If you're expanding rear storage capacity on an SR650 V4 — adding a rear drive cage populated with large-format HDDs or SAS drives — this kit provides the internal cabling backbone that connects those drives to the server's SAS controller. Without it, the rear bay cage has no signal path to the backplane. The SAS interface ensures compatibility with the high-throughput storage controllers used in the SR650 V4 architecture, keeping data transfers off the slower SATA bus where sustained sequential workloads demand it.

Compatibility

This cable kit is specific to the Lenovo ThinkSystem SR650 V4 rack server. It is not a universal SAS cable — the connector layout, cable routing length, and backplane pin assignments are engineered to the SR650 V4 chassis. Do not attempt to use this kit with SR650 (Gen 1), SR650 V2, or SR650 V3 platforms; physical and electrical compatibility is not guaranteed across generations. For rear storage expansion options on other server storage components or related SAS cable assemblies, verify the chassis generation before ordering. At 10 lb, the kit weight is consistent with a multi-cable harness assembly — budget accordingly for installation ergonomics in a populated rack.

Installation Notes

Route cables prior to populating the rear drive bays — access to backplane connectors is significantly reduced once drives are installed. SAS cable assemblies of this type are keyed at both ends; do not force connectors. Confirm the SAS controller HBA or RAID adapter in your SR650 V4 is configured to address the rear bay zone before powering on with drives installed. Country of origin is Mexico (MX).
