Lenovo 4X97B03872 SR650 V4 2.5 Front BP3 SAS Cable KIT

Lenovo 4X97B03872 SR650 V4 2.5-Inch Front Backplane 3 SAS Cable Kit

Overview

The Lenovo 4X97B03872 is a SAS cable kit designed for the ThinkSystem SR650 V4 server, specifically wiring the 2.5-inch Front Backplane 3 (BP3) to the system's SAS/SATA controller. If you're expanding drive capacity on an SR650 V4 by populating the third front backplane position, this kit provides the exact routing harness needed — using mismatched or generic SAS cables in a dense 2U chassis introduces signal integrity risk and conflicts with Lenovo's validated cable routing paths. At 10 lb, the kit ships with the hardware required to complete the backplane-to-controller connection for this specific configuration.

Compatibility

Designed exclusively for the Lenovo ThinkSystem SR650 V4 2U rack server with a 2.5-inch drive bay configuration and a populated Front Backplane 3 slot. This kit is position-specific — it is not interchangeable with BP1 or BP2 cable kits, nor compatible with prior SR650 generations (V2, V3) or adjacent platforms such as the SR630 V3 or SR650 V3. Confirm your chassis drive-bay layout and backplane slot assignment against Lenovo's SR650 V4 hardware maintenance manual before ordering. For related server storage accessories and server cable kits, verify the exact backplane slot and controller pairing required for your build.

Installation Notes

Route cables per the SR650 V4 cable routing diagrams in Lenovo's hardware maintenance documentation — the 2U chassis has strictly managed airflow paths and cable routing lanes that must be followed to avoid blocking fan zones or creating signal interference. SAS interface; confirm controller port availability and backplane connector orientation before installation. Country of origin: Mexico.
