Lenovo 4X97B03883 SR650 V4 2.5IN 36 NVME Cable KIT

Lenovo 4X97B03883 SR650 V4 2.5-Inch 36-Drive NVMe Cable Kit

Overview

The Lenovo 4X97B03883 is a factory-configured NVMe cable kit designed for the ThinkSystem SR650 V4 rack server when fitted with the 2.5-inch, 36-bay drive backplane. If you are expanding an SR650 V4 to its full 36-drive NVMe capacity, this kit provides the internal cabling harness required to connect the backplane to the system board — an integration step that cannot be completed with generic cables. The 4X97B03883 ships at 10 lb, reflecting a complete, multi-cable harness rather than individual runs.

Compatibility

This kit is specified for the Lenovo ThinkSystem SR650 V4 server platform in the 2.5-inch 36-drive NVMe configuration. It is not interchangeable with SR650 V3, SR650 (Gen 1/2), or other ThinkSystem chassis — NVMe signal routing and connector keying differ across generations. Verify your server's chassis generation and backplane part number before ordering. This kit is not applicable to SAS/SATA backplane configurations; the NVMe interface is specific to direct-attach PCIe storage paths used in high-density storage-intensive deployments such as NVR-class or AI inference servers built on SR650 V4 hardware.

Installation Notes

Installation requires access to the server interior with the chassis powered down and racked safely. Route each cable according to Lenovo's SR650 V4 hardware maintenance guide — cable routing channels inside the chassis are specific to the 36-bay configuration, and incorrect routing can obstruct airflow or create tension on connectors. The NVMe interface carries high-speed PCIe signal; do not extend, splice, or substitute individual cables. Country of origin is Mexico (MX); UNSPSC commodity code 26121624 applies for procurement classification.
