Juniper EX9208-BASE3B-AC Chassis

Juniper EX9208-BASE3B-AC is a base EX9208 chassis configuration designed for high-performance campus core, aggregation, and data center deployments. It includes an 8-slot chassis with passive midplane, one EX9200-RE2 Routing Engine, one EX9200-SF2 switch fabric-2 module, one fan tray, and three 2520W AC power supplies, along with blank panels for unused slots.

As part of the EX9200 Series, the EX9208 platform delivers scalable modular architecture, high port density, and strong resiliency with support for fabric redundancy, redundant Routing Engines (in supported configurations), and hot-swappable system components. The chassis supports a wide range of EX9200 line cards for flexible 1GbE, 10GbE, 25GbE, 40GbE, and 100GbE deployments.

This base configuration is suitable for organizations that need a powerful modular switching foundation and want the flexibility to expand with additional line cards, switch fabric modules, routing engines, and power supplies as network requirements grow.
