Mikrotik CRS310-1G-5S-4S+IN — 1U Rackmount 10G Switch (5×1G SFP, 4×10G SFP+, 1×GigE)

Compact 1U rack switch designed as a direct upgrade path for CRS212 systems. The CRS310-1G-5S-4S+IN delivers mixed-speed fiber and copper connectivity with five 1G SFP ports, four 10G SFP+ ports and an additional Gigabit Ethernet port for flexible deployment. Performance and hardware - ARM v7 CPU and 256 MB RAM provide the device’s control-plane processing. - Advanced Marvell switch chips handle high-throughput packet switching. - Hardware-offloaded VLAN filtering and partial Layer-3 routing reduce CPU load and improve forwarding efficiency. Ports and power - Five 1G SFP and four 10G SFP+ ports support fiber links; ideal for indoor 10 Gigabit fiber runs up to 100 meters. - The extra Gigabit Ethernet port is wired directly to the switch chip to guarantee full gigabit throughput and supports PoE-in for flexible powering options. Why choose this model - Rackmountable in a standard 1U chassis for tidy installation in network racks. - Suited for minimizing latency and packet loss on short 10G fiber links while also reducing electromagnetic interference and offering better protection against tampering and eavesdropping. This unit combines compact rack-ready design with mixed 1G/10G fiber connectivity and hardware-accelerated switching features for reliable, high-performance network aggregation.
