Lenovo 4X97A90338 SR650 V3 2.5IN Rear BP NVME CBL KIT

Lenovo 4X97A90338 SR650 V3 2.5-Inch Rear Backplane NVMe Cable Kit

Overview

The Lenovo 4X97A90338 is a factory-new NVMe cable kit designed specifically for the rear 2.5-inch drive backplane on the ThinkSystem SR650 V3 server. If you're adding rear NVMe storage capacity to an SR650 V3 — expanding for higher-density workloads or reconfiguring the rear bay from SAS/SATA to NVMe — this kit provides the signal cabling required to connect the backplane to the system board. Without it, the rear backplane has no NVMe signal path; the drives will not be recognized. This is a genuine Lenovo option part (4X97A90338), not a generic aftermarket cable assembly.

Compatibility

Designed for the Lenovo ThinkSystem SR650 V3 rack server platform. This cable kit pairs with the SR650 V3 rear 2.5-inch backplane option — confirm your chassis configuration includes a rear drive cage before ordering. It is not interchangeable with SR650 V2 or SR630/SR850 variants; Lenovo's rear backplane cable assemblies are generation- and chassis-specific. Verify your server's current backplane and available PCIe/NVMe controller slots against the SR650 V3 option compatibility matrix before procurement. Interface standard is NVMe.

Installation Notes

Installation requires access to the SR650 V3 system board NVMe connectors and the rear backplane signal port. Route the cable per the SR650 V3 service guide to avoid pinch points at the drive cage. The kit weighs 10.00 lb as packaged — the bulk of that is protective packaging, not cable mass. Sourced from MX (Mexico) manufacturing.
