HPE ML350 G11 DW PWR CBL KIT NVIDIA L40 - P47221-B21

HPE P47221-B21 ML350 Gen11 Dual-Wide Power Cable Kit for NVIDIA L40

Overview

The P47221-B21 is HPE's dual-wide power cable kit for the ProLiant ML350 Gen11 tower server, engineered specifically to support NVIDIA L40 GPU installations. When you add a high-draw accelerator like the L40 into an ML350 Gen11 chassis, the standard internal power routing is insufficient — this kit provides the correct cable geometry and connector configuration to deliver stable power to the GPU without improvising with third-party adapters that may not meet HPE's internal clearance or current-rating requirements. If you're deploying ML350 Gen11 systems as GPU compute nodes for AI inference, rendering, or video analytics workloads, this cable kit is a required line item, not an optional accessory.

Compatibility

Designed for the HPE ProLiant ML350 Gen11 tower server platform with dual-wide GPU configurations. Validated for use with the NVIDIA L40 GPU. The dual-wide form factor targets full-height, full-length double-slot cards — do not use with single-wide or half-height GPU options in the same chassis, as connector and cable routing differ. Confirm your ML350 Gen11 power supply option supports the additional GPU load before installation; HPE's high-performance power supply configurations are typically required alongside GPU expansion.

Installation Notes

Route cables per HPE's internal cable management guidelines for the ML350 Gen11 chassis to avoid airflow obstruction across the GPU heatsink. Country of origin is the United States. Weight is 1.00 lb. UNSPSC commodity code 26121629 (power cable assemblies) applies for procurement classification. Pair with HPE's ML350 Gen11 GPU enablement kit if not already included in your configuration — the power cable alone does not address GPU riser or bracket requirements.
