CRS804 DDQ
The MikroTik CRS804-4DDQ-hRM is a compact, cost-effective 400 Gigabit Ethernet switch designed for AI clusters, storage fabrics, and next-generation core or aggregation networks. Featuring 4× 400G QSFP-DD, dual 1/10G ports, hot-swap redundant power, and RouterOS v7, it delivers wire-speed performance without enterprise pricing.
The CRS804-4DDQ-hRM brings 400 Gigabit switching into a practical and affordable form factor. Designed for AI workloads, GPU clusters, storage fabrics, and high-speed aggregation, it provides predictable, low-latency, wire-speed performance in a quiet and efficient 1U rack design.
At its core is a powerful Marvell 98DX7335 switch chip, paired with a quad-core 2.0 GHz ARM64 CPU, 4 GB DDR4 RAM, and RouterOS v7 (License Level 6). This combination delivers advanced traffic control, high-performance switching, and a familiar MikroTik management environment trusted worldwide.
The switch features 4× 400G QSFP-DD ports, each built from eight independent lanes. This allows flexible breakout options such as 2×200G, 100G, 50G, or 40G, making the CRS804 ideal for gradual upgrades in existing networks. Two additional 1G/10G Ethernet ports provide management or uplink flexibility.
Designed for long-term reliability, the CRS804-4DDQ-hRM includes dual hot-swap power supplies, hot-swap cooling fans, and efficient airflow. Even at full load with optics installed, power consumption remains impressively low for a 400G platform.
Whether deployed as a compact spine, core switch, or high-speed aggregation layer, the CRS804-4DDQ-hRM delivers enterprise-grade 400G performance at a fraction of traditional market cost — with no subscriptions or feature lock-ins.
