Silver 1U rackmount switch with twelve RJ45 ports and four combo cages

Mikrotik

Mikrotik CRS312-4C+8XG-RM 12-Port 10G RJ45 Smart Switch

SKU CH-VMKR-KSNMB

A 12-port 10G RJ45 smart switch with four combo ports for fibre, dual power supplies and 120 Gbps non-blocking throughput

  • 12 ports give 10 Gbps RJ45 density for high-speed copper networks
  • 4 combo ports add SFP+ flexibility for fibre uplinks when needed
  • 120 Gbps non-blocking throughput handles heavy workloads without congestion
  • Dual power supplies keep the switch running if one feed fails
  • 1U rackmount case with console and USB fits standard cabinets

12-Port 10G Smart Switch

The Mikrotik CRS312-4C+8XG-RM is a 1U rackmount switch offering twelve 10G connections. Eight ports are fixed RJ45 while four combo ports accept either RJ45 or SFP+ modules. It runs RouterOS or SwOS for Layer 3 routing and switching features. Dual redundant power supplies help maintain uptime during critical workloads.

Suited for High-Throughput Workstations

This switch targets teams moving huge data files continuously in multimedia production, scientific research, game development or big-data analysis. The 120 Gbps non-blocking throughput and 178 Mpps forwarding rate handle sustained 10G traffic. Buyers needing Power over Ethernet or more than twelve ports should consider other models.

Straightforward Rack Installation

The 1U chassis mounts in any standard rack and uses front-to-rear airflow. Combo ports are software-selectable via RouterOS scripting, so incorrect mode selection is the most common setup issue. A console port and full-size USB provide direct management access if network configuration becomes unreachable.

Questions about this item

What type of SFP+ modules do I need for the 4 combo ports?

The four combo ports accept standard 10G SFP+ transceivers when you choose fibre instead of the built-in 10G RJ45 interfaces.

Can the 8 fixed 10G RJ45 ports and the 4 combo ports all pass traffic at the same time?

Yes, all twelve 10G links operate simultaneously; the combo ports are independently selectable so copper and fibre links coexist without blocking.

Which LEDs or counters confirm the switch is forwarding at line rate?

The front-panel port LEDs show link and activity per port, while RouterOS reports a total non-blocking throughput of 120 Gbps and a forwarding rate of 178 Mpps.
