CRS804 DDQ

A compact 1U 400G switch built for AI clusters, storage fabrics, and high-speed aggregation, featuring four 400G QSFP56-DD ports, dual 10 Gigabit Ethernet, and RouterOS v7. With hot-swap power supplies, robust cooling, and low power consumption, it delivers ultra-high bandwidth, wire-speed performance, and future-proof scalability at an accessible price point.

The CRS804 DDQ is a compact and reliable 400 Gigabit switch designed for modern AI workloads and next-generation network upgrades. With four 400G QSFP-DD ports and dual 1/10G Ethernet, it delivers exceptional bandwidth density in a quiet and efficient 1U form factor. The CRS804 DDQ is designed for long-term reliability and low cost of ownership, supported by hot-swap power supplies (included!), robust cooling, and low power consumption that reaches only 123 W at full load with optics installed.
 
AI and GPU clusters
A perfect building block for small to medium AI installations. It delivers predictable, low-latency performance and full wire-speed switching, keeping GPU nodes and storage traffic flowing without bottlenecks. The compact design and low power usage make it suitable for AI labs, research environments, and smaller rack deployments.
 
Future-proofing for existing networks
The CRS804 DDQ can act as a high-speed core or aggregation switch even in older racks. Each 400G QSFP-DD port is built from eight independent data lanes. This enables flexible breakout options, including two 200G links for AI workloads or lower-speed connections such as 100G or 40G. You can deploy the CRS804 DDQ in your existing network today and upgrade to higher speeds over time without replacing the switch. With the right breakout cables, the CRS804 DDQ can interconnect virtually any device with SFP or QSFP ports, regardless of generation.
