The MikroTik CRS804 DDQ is a next-generation 400 Gigabit rackmount switch engineered to meet the demanding needs of modern networks, from AI and GPU clusters to high-performance storage fabrics and next-level aggregation layers.
Designed in a compact 1U form factor, this powerhouse delivers four native 400G QSFP56-DD ports alongside two flexible 1/2.5/5/10 GbE Ethernet interfaces, enabling dense, ultra-fast connectivity in environments where performance and efficiency matter most.
At its core, the switch combines a robust Marvell 98DX7335 switching ASIC with a quad-core 2.0 GHz ARM CPU, 4 GB of DDR4 RAM, and the familiar RouterOS v7 operating system, giving you both advanced traffic control and versatile management tools right out of the box.
Built with real-world reliability in mind, the CRS804 DDQ features dual redundant hot-swap power supplies and modular cooling fans that can be serviced without interrupting operation, ensuring consistent uptime even during maintenance or component replacement.
Its energy-efficient design keeps power consumption relatively low — around 123 W at full load — while the included RMK-2x10/19 mounting kit lets you install two switches in a single 1U space, maximising rack efficiency.
Whether deployed as a high-speed core, an aggregation point, or the backbone of a compact data centre, this switch offers the blend of performance, scalability, and dependable engineering that professionals look for in mission-critical infrastructure.
