Product Review

The Juniper EX9204-CHAS offers a backplane capacity of up to 3.2 Tbps and maximum fabric bandwidth of 480 Gbps/slot, which supports high-density 10GbE, 40GbE, and 100GbE port configurations, catering to diverse networking demands. However, the chassis occupies 5 rack units and a fully loaded configuration weighs 128 lbs, which may pose challenges in terms of space efficiency and installation in denser rack environments. Additionally, with only two slots available for line cards when opting for fabric redundancy, there's a trade-off between high availability and port density that needs consideration.


The Juniper EX9204-CHAS is a 4-slot chassis designed to deliver high-performance, flexibility, and scalability for enterprise core, aggregation, and high-density Ethernet environments. It features a passive midplane and a backplane capacity of up to 3.2 Tbps, ensuring efficient data flow across the network infrastructure. This chassis offers a maximum fabric bandwidth of 480 Gbps per slot, supporting the needs of data-intensive applications and services. With dimensions of 17.5 x 8.7 x 27.75 inches and a 5U rack unit size, the EX9204-CHAS is engineered to fit into standard data center racks, optimizing space without compromising performance. The base configuration weight is 68.3 lbs, with a fully loaded chassis reaching up to 128.0 lbs, demonstrating its capacity to house a significant amount of networking hardware. This chassis supports a high port density, making it ideal for networks requiring a large number of connections: - Maximum 10GbE port density (wire speed) of 144 (96) - Maximum 40GbE port density (wire speed) of 36 (24) - Maximum 100GbE port density (wire speed) of 12 (8) The EX9204-CHAS is designed to operate within a wide range of temperatures and altitudes, ensuring reliability under various environmental conditions. Operating temperatures range from 32°F to 104°F, with storage temperatures spanning from -40°F to 158°F. It can function at altitudes up to 10,000 feet, and handle relative humidity levels from 5% to 90% (non-condensing) during operation, and 5% to 95% (non-condensing) when not in operation. The chassis accommodates a total of 4 slots, with 2 available for line cards when fabric redundancy is configured, or 3 without. This flexibility allows network architects to tailor the system to meet the specific redundancy and performance requirements of their network infrastructure. Equipped with 16 gigabytes of DRAM, the EX9204-CHAS is capable of handling complex network operations and sustaining multiple processes simultaneously, ensuring smooth and efficient network performance. Key hardware specifications include:
  • Backplane capacity of up to 3.2 Tbps
  • Maximum fabric bandwidth per slot of 480 Gbps
  • Weight ranges from 68.3 lbs in a base configuration to 128.0 lbs when fully equipped
The Juniper EX9204-CHAS stands out for its ability to support high-density Ethernet connections and its adaptability to a range of environmental conditions, making it a suitable choice for enterprises looking to build or expand their networking infrastructure with a focus on scalability and reliability.
