HPE DL300 GEN10+ GPU 8P Keyed CBL KIT - P39102-B21

HPE P39102-B21 DL300 Gen10+ GPU 8-Port Keyed Cable Kit

Overview

The P39102-B21 is an OEM cable kit designed to wire GPU expansion into HPE ProLiant DL300 Gen10+ platforms. Eight keyed connectors eliminate mis-seating during GPU commissioning — a real advantage in dense rack builds where cable orientation errors cause undetected power faults. At 0.45 lb and 10.50 × 8.50 × 0.50 in, the kit stows flat and routes without bulk inside a 2U/4U chassis bay.

Compatibility

Designed for the HPE ProLiant DL300 Gen10+ server family. Verify your specific ProLiant server model against HPE's QuickSpecs for the DL300 Gen10+ platform before ordering — GPU cable routing and keying vary by chassis sub-variant. This kit is not interchangeable with Gen9 or earlier DL300 cable assemblies, nor with DL500/DL600-series GPU kits.

Installation Notes

Keyed connectors are orientation-specific — each of the eight ports seats in one direction only, reducing the risk of reversed polarity during a GPU server upgrade. Route cables before fully seating GPUs to preserve clearance in tight bays. HPE recommends following the DL300 Gen10+ maintenance and service guide cable-routing diagrams; incorrect routing can block airflow across GPU heatsinks and trigger thermal throttling under sustained compute load. No additional tools are specified in the available evidence beyond standard ESD precautions.
