Product ID: CRS312-4C+8XG-RM
Supplier: Mikrotik
Description: Multi-Gigabit Smart Switch with 10G Ethernet and SFP+ Combo Ports (Rackmount)

The CRS312-4C+8XG-RM is a forward-looking multi-gig smart switch designed for modern networks transitioning to 10 Gigabit Ethernet over copper while retaining fiber flexibility. As MikroTik’s first switch to combine 10G RJ45 Ethernet with SFP+ connectivity, it delivers a versatile platform for enterprise, SMB core, and high-performance access deployments.

The switch features eight 10G RJ45 Ethernet ports for high-speed copper connections and four combo ports that can operate as either 10G Ethernet or SFP+, allowing seamless integration of copper and fiber links. This makes it ideal for environments upgrading servers, storage, and workstations to 10G without replacing existing fiber infrastructure.

Powered by an ARM-based architecture and supporting dual boot (RouterOS v7 or SwOS), the CRS312-4C+8XG-RM offers flexibility between simple managed switching and more advanced configurations including VLANs, monitoring, ACLs, and light Layer-3 routing. Its 1U rackmount metal chassis is built for reliable operation in network closets, IDFs, and data-center edge environments.
