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.
