MikroTik CRS804-4DDQ-hRM 400G QSFP56-DD Switch
Product code: CRS804-4DDQ-hRM
The MikroTik CRS804-4DDQ-hRM is a compact 1U 400 Gigabit switch designed for high-bandwidth fabrics, AI and GPU clusters, all-flash storage networks and future-ready backbone upgrades.
Use CRS804-4DDQ-hRM where 400G uplinks, dense high-speed switching and MikroTik RouterOS v7 management are required in a cost-effective rackmount form factor.
Four 400G QSFP56-DD ports
Four QSFP56-DD interfaces provide 400G connectivity and support breakout modes down to 1G, 2.5G, 5G, 10G, 25G and 50G.
Dual 1G/10G Ethernet
Two RJ45 Ethernet ports support 10M, 100M, 1G and 10G modes for management or flexible connectivity.
High-speed switch silicon
The Marvell 98DX7335 switch chip is built for wire-speed switching across the 400G port set.
Enterprise rack hardware
Dual redundant AC inputs, hot-swap power supplies, hot-swap cooling fans and RouterOS v7 support demanding network environments.
