Cornelis CN5SWE48G2AF CN5000 48-Port 400G Omni-Path Switch

Cornelis CN5SWE48G2AF CN5000 48-Port 400G Omni-Path Switch

The Cornelis CN5SWE48G2AF CN5000 Omni-Path switch provides 48 QSFP112 ports with 400Gbps performance per port for artificial intelligence and high-performance computing clusters. Its lossless, congestion-free fabric architecture supports demanding scale-out networks while maintaining low tail latency, reliable packet delivery, and efficient communication between compute nodes.

Designed for AI training, real-time inference, and mission-critical HPC applications, this 48-port 400G network switch delivers 38.4Tbps of aggregate bidirectional bandwidth. Fine-grained adaptive routing, incast-aware flow control, and configurable virtual lanes help optimize message rates and reduce congestion across highly parallel workloads.

The air-cooled 1.7RU chassis uses fan-to-port airflow and dual 240/277 VAC power supplies for data-center deployment. Hot-swappable fans and power supplies simplify maintenance, while secure boot, integrated management, real-time telemetry, and in-band or out-of-band administration support dependable operation within scalable Cornelis CN5000 Omni-Path environments.
