MicroTik CRS312-4C+8XG-RM

MikroTik Cloud Router Switch CRS312-4C+8XG-RM is the first manageable MicroTik switch with 10G RJ45 Ethernet ports. It is equipped with 8 10G Ethernet and 4 10G Combo ports (10G Ethernet / SFP+).
CRS312-4C+8XG-RM gives access to up to 12 ports with 10 Gb/s throughput. The Combo ports allow for a connection via fiber optic cable, which extends the capabilities of the switch. The device has a switching capacity of 240 Gb/s, and the speed of packet transfer is 178 Mp/s. The device's 10G Ethernet ports support connection speed negotiation and can therefore be used at 1G, 2.5G, 5G or 10G speeds.

MicroTik CRS312-4C+8XG-RM

Two types of operating systems

Thanks to the Dual Boot function the user can select one of two operating systems in the device, RouterOS (Level 5) and SwitchOS. The first option has Layer3 functions, while the second one is characterized by simplicity of use, but is limited only to Layer2.
