Lenovo 4X97B02426 ThinkSystem V3 2U BlueField-3 B3220 Power Cable Kit

Overview

The 4X97B02426 is a purpose-built power cable kit for integrating the NVIDIA BlueField-3 B3220 data processing unit (DPU) into Lenovo ThinkSystem V3 2U rack servers. DPU cards require a dedicated internal power feed separate from the standard PCIe slot — this kit supplies the correct cable assembly to make that connection cleanly inside a 2U chassis, keeping the installation factory-tidy and avoiding field-improvised wiring that can cause intermittent power faults under load. If you are deploying a BlueField-3 B3220 in a ThinkSystem V3 2U platform and the cable kit did not ship with your card or server, this is the part to source. At 1.00 lb, it ships light and is typically a single-line add to a server accessory order.

Compatibility

Designed for Lenovo ThinkSystem V3 2U rack servers paired with the NVIDIA BlueField-3 B3220 DPU. The 2U chassis form factor is a hard constraint — do not attempt to use this kit in ThinkSystem 1U platforms or non-V3 generation systems, as internal cable routing, connector placement, and available slack length differ by chassis generation. Confirm your server model is a V3-generation 2U before ordering. For broader server accessory compatibility across the ThinkSystem line, verify the specific server model's hardware maintenance manual before installation.

Installation Notes

Route the cable per the ThinkSystem V3 2U hardware maintenance guide — cable management is tight in 2U enclosures and improper routing near fans or drive backplanes can restrict airflow or cause abrasion over time. Seat all connectors fully before powering on; a partial connection on the DPU power feed will prevent the card from initializing and may not throw an obvious fault at POST. No special tools are required beyond standard server-assembly precautions (ESD strap, system powered down and unplugged).
