MikroTik CRS312-4C+8XG-RM — 10G enterprise switch for SMB and corporate infrastructures

MikroTik CRS312-4C+8XG-RM is the first MikroTik switch with 10G RJ45 ports, combining eight copper 10G ports with four 10G RJ45/SFP+ combo ports — usable simultaneously or software-selectable for maximum flexibility between copper and fiber connectivity. It is the solution for professionals working with large data volumes who need real 10G speed without the limitations of a conventional Gigabit switch.

Eight 10G RJ45 ports connect servers, workstations, and NAS devices at full 10G speed over existing Cat6/Cat6A cabling, without replacing the cable infrastructure. The four 10G RJ45/SFP+ combo ports activate independently through RouterOS scripting, adding fiber connections when the network requires it. Non-blocking throughput of 120 Gbps and switching capacity of 240 Gbps eliminate any internal bottleneck. Dual redundant power supplies prevent unplanned downtime in critical installations where 24/7 availability is essential. A full-size USB port and RJ45 serial console port complete the management options.

CRS312-4C+8XG-RM supports dual boot between RouterOS v7 license level 5 and SwOS — RouterOS for advanced Layer 3 features with routing, scripting, and VPN, SwOS for streamlined switching-focused configuration. The 1U rackmount enclosure with included rack ears fits any standard 19-inch rack. Active cooling via four fans maintains stable operating temperature under continuous load.

Recommended for multimedia production studios, research and big data analysis teams, game development environments, and any professional setting where fast transfer of large files between workstations, servers, and NAS devices is a daily requirement, as well as network infrastructures where a 10G switch with power redundancy and RJ45/SFP+ combo ports delivers the best flexibility-to-performance ratio. RouterOS v7 level 5 license and free lifetime software updates are included.
