A cluster administrator needs to validate transceiver firmware versions across 200 ports using UFM.

Managing a large-scale AI fabric requires centralized visibility into the physical layer. The NVIDIA Unified Fabric Manager (UFM) provides a comprehensive Dashboard for InfiniBand networks. To check transceiver firmware—which is critical for ensuring feature parity and stability across the fabric—the administrator can use the UFM Enterprise GUI. By navigating to the " Devices " section and selecting a specific switch, the " Cables " tab will aggregate telemetry for every occupied port. This view displays the manufacturer, part number, and the specific firmware version of the transceivers (LinkX) or Active Optical Cables (AOC). This consolidated view is far more efficient than manual CLI queries (Option C) for 200+ ports. Maintaining uniform firmware across transceivers ensures that optimizations like Adaptive Routing and Congestion Control perform consistently across the entire 400G or 200G fabric.
