Introduction

This document details deploying the North-South Networking for a DGX GB200 NVL72 SuperPod.

You must complete the physical installation of the network switches (SN5600 and SN2201) before you deploy the switches, either manually, or from within the tool included in BCM 11. In addition, you can find information about the intended deployment in a site information blueprint (SIB).

Overall, the DGX SuperPOD Deployment Guides contain essential information and should be consulted before deploying the configuration:

• NVIDIA DGX SuperPOD

• Ethernet Switching for AI and the Cloud | NVIDIA
