Our take on the Mikrotik CRS312-4C+8XG-RM Cloud Router Switch

The MikroTik CRS312-4C+8XG-RM is a rackmount 12-port 10-gigabit switch: eight copper 10GbE RJ45 ports plus four 10GbE SFP+ combo ports that also accept 1G. It runs RouterOS, so it can act as a switch, a router, or both, with VLANs, link aggregation, and a dual-core CPU for management. It suits small offices, labs, and home labs that need many 10G copper links without paying per-port enterprise prices. Against fanless MikroTik models it adds copper 10G density and rack ears, but it is louder and needs more setup than a plain unmanaged switch.

Questions and answers

Can it work as a router as well as a switch?
Yes. It runs RouterOS, so it can route between VLANs and subnets, run a firewall, and switch at the same time. Heavy routing loads are limited by its dual-core CPU.
Do the SFP+ ports support 1G?
Yes. The four combo ports accept 10G SFP+ and 1G SFP modules, so you can mix fiber and copper uplinks. They do not take 10G copper SFP+ modules in every case, so check module compatibility.
Is it fanless?
No. It has active cooling, and owners report audible fan noise. Plan for a closet or rack rather than a quiet room.
Does it support PoE?
No. None of the ports supply PoE, so access points and cameras need separate injectors or a PoE switch.
How does it compare with the CRS309?
The CRS309 is smaller and fanless with SFP+ cages only. This model adds eight 10G copper RJ45 ports and rack mounting, at the cost of fan noise.
What is in the box?
The switch, rackmount ears, and power supply. SFP modules and cables are not included.
