Your Ticket to the 400G Future: Performance Without Compromise
With the CRS804-4DDQ-hRM, MikroTik breaks the sound barrier of Network performance. This Cloud Router Switch is not just an upgrade – it's a quantum leap. Developed for environments where every millisecond counts, it delivers the brute force performance of 400 Gbit/s per port. Whether you operate a powerful AI cluster, manage a data center, or build the backbone infrastructure for an ISP, this Switch ensures your data flows without bottlenecks. Experience performance previously only possible with extremely expensive hardware, and secure a decisive competitive advantage.
Maximum Flexibility for Your Growing Network
The true strength of the CRS804-4DDQ-hRM lies in its incredible adaptability. The four QSFP-DD ports are not limited to 400G. Thanks to the intelligent breakout function, you can split each port into multiple slower connections. Do you need four 100G links for your servers? No problem. Do you need to connect a mix of 40G and 100G devices? The CRS804 makes it possible. This flexibility protects your investment and allows you to gradually modernize your Network without having to replace all hardware with every technological leap. It is the perfect central Ethernet Switch for dynamic environments.
Built for Continuous Operation: Reliability in Focus
In critical infrastructures, there is no room for failures. MikroTik has understood this and consistently designed the CRS804-4DDQ-hRM for reliability. Two redundant power supplies, which can be hot-swapped during operation, ensure an uninterrupted Power Supply. Should one Power Supply fail, the other seamlessly takes over. The same principle applies to the two hot-swappable fan modules, which keep the system cool even under full load. With an MTBF of approximately 200,000 hours, this Switch is designed for years of low-maintenance operation in your 19-Inch Racks.
The Power of RouterOS: Unlimited Control
What good is the best hardware without intelligent software? The CRS804-4DDQ-hRM comes with MikroTik RouterOS v7 and the highest license level (Level 6). This gives you full control over your Network. Configure complex Layer-3 routing scenarios with BGP or OSPF, create detailed firewall rules, manage VLANs, or implement Quality of Service. Compared to other MikroTik Switches, this model offers the ultimate combination of raw port speed and the proven, granular configurability of RouterOS. You have the tools to precisely implement every Network requirement.

Frequently Asked Questions (FAQ)
Can I use the MikroTik CRS804-4DDQ-hRM in my existing 100G Network?
Yes, absolutely. Thanks to the breakout function, you can split a 400G port into up to four separate 100G connections using suitable Cabling and transceivers, seamlessly integrating it into your existing Network infrastructure.
Is this Switch suitable for a small office or home Network?
No, this device is designed for use in data centers, by internet providers, or in highly specialized environments such as AI clusters and storage Networks. For an office or home Network, it is technologically and financially oversized.
What is the power consumption of the CRS804-4DDQ-hRM during operation?
The maximum power consumption is 123 watts under full load with all ports active. Without inserted Modules (transceivers), the consumption is approximately 92 watts.
Which operating system runs on the Switch and is a license required?
The Switch comes with MikroTik RouterOS v7 and the highest license level (Level 6). No additional license costs are required to use the full range of functions of this MikroTik Router.
Does the Switch support Layer-3 routing protocols like BGP or OSPF?
Yes, thanks to RouterOS Level 6, the Switch fully supports dynamic routing protocols like BGP and OSPF, allowing it to act as a full-fledged core MikroTik Router in the Network.
Is the Switch loud? Can it be placed in an office?
Although described as 'quiet' for its performance class, the Switch has two active fans and is intended for operation in an air-conditioned server room (1U-Rack). Placement in a quiet office environment is not recommended for this type of 19-Inch Racks device.
