MikroTik CRS804 DDQ – Compact 400G Switch for High-Density Aggregation

The MikroTik CRS804 DDQ is a compact 1U 400 Gigabit switch designed for high-performance aggregation, storage fabrics, and modern AI-driven network environments. It delivers ultra-high bandwidth in a space-efficient form factor, making it well suited to deployments where density, efficiency, and scalability are critical. With four 400G QSFP56-DD ports and dual Ethernet ports supporting 1G and 10G connectivity, it provides a flexible foundation for next-generation network architectures.

Internally, the CRS804 DDQ combines a Marvell 98DX7335 switching chipset with a quad-core 2.0 GHz ARM processor, 4 GB of DDR4 memory, and RouterOS v7. This enables advanced switching, traffic management, and routing capabilities within the familiar MikroTik management environment. Each 400G interface is built from multiple data lanes, allowing flexible breakout configurations to support a wide range of current and future network speeds.

Designed for reliability and long-term operation, the CRS804 DDQ features hot-swappable power supplies, robust cooling, and efficient power consumption even under full load. Its quiet operation and compact footprint make it suitable for data centres, AI labs, edge compute deployments, and enterprise racks. The included rack-mounting accessory allows two units to be installed within a single 1U space, maximising rack efficiency.
