Product overview

The Extreme Networks SLX 9850-4 (SKU BR-SLX9850-4-BND-DC) is a 4-slot modular Ethernet router switch chassis designed for datacenter deployments. It features 4 high-speed interface module slots supporting up to 144 100GbE ports, 240 40GbE ports, 960 10GbE ports via breakout, or 288 1GbE ports. The chassis includes 5 switch fabric modules for 115 Tbps non-blocking capacity, 3 hot-swappable fan modules with front-to-back airflow, and 2 x 3000W DC hot-swappable power supplies. One management module with IPv4/IPv6/MPLS support is included, expandable to 2. It scales to 750,000 MAC addresses, 1,500,000 IPv4 routes, and 140,000 IPv6 routes with OptiScale. Measuring 10 RU (17.5 in high), it weighs 107 lbs empty, up to 303 lbs fully loaded. Low latency under 4 microseconds suits high-performance computing, cloud, and service provider networks requiring dense, scalable Layer 3 routing.
