Remove the bottleneck from your network setup. It is time to upgrade that 1 Gigabit switch to something truly powerful and enjoy real speed. Introducing CRS312-4C+8XG-RM, our first product with 10G RJ45 Ethernet ports. Moreover, it also has 4 x 10G combo ports: use them for 10G RJ45 Ethernet or 10G SFP+, when you need an additional fiber connection. Combo ports can be used alongside the 8 regular 10G RJ45 Ethernet ports at all times. These ports can also be software-selected, so you can use RouterOS scripting to decide which combo ports will be active.
This device is a practical solution for those who work with huge data files and need a fast, capable connection 24/7: multimedia production, scientific research, game development, big data analysis, and so on. CRS312-4C+8XG-RM has a dual power supply for redundancy and no unexpected downtime when deadlines are looming. It has a full-size USB, a console port for configuration, and a 1U rackmount case that fits all the standard racks.
You can choose between our legendary feature-packed RouterOS for booting or a simpler, but still powerful SwOS. If you would like the ability to use routing and other Layer 3 features in your CRS, use RouterOS.
This switch has a great total non-blocking throughput of 120 Gbps, switching capacity of 240 Gbps, and a forwarding rate of 178 Mpps. CRS312-4C+8XG-RM – built for professionals, great for everyone!
