MikroTik Cloud Router CRS112-8G-4S-IN – 8-Port Gigabit Cloud Router Switch with 4 SFP for SMB Networks

MikroTik CRS112-8G-4S-IN is a compact Layer 3 managed switch for small offices and distribution points, featuring 8 Gigabit Ethernet ports and 4 SFP ports for fiber connectivity, designed for SMB networks where a managed switch with optical uplink is needed at minimal size and cost. Commonly deployed as an access switch in distributed networks, it delivers full switching and routing functionality in a completely silent desktop enclosure.

Eight Gigabit ports handle full office device connectivity while four SFP ports enable fiber uplinks of up to 1 Gbps to the network core or inter-site optical links between office locations. Flexible powering via DC jack or Passive PoE with a wide 10-57 V input range ensures compatibility with various existing power sources without additional adapters. At just 10 W maximum draw with passive cooling, the switch operates silently in any open office environment.

CRS112-8G-4S-IN runs RouterOS level 5, allowing each port to be independently configured for switching or routing without additional hardware. It supports VLAN management, traffic filtering and full Layer 3 functionality through the familiar RouterOS interface. Management is available via Winbox, SSH and web interface with current, voltage and PCB temperature monitoring for operational safety.

Recommended for small offices needing a compact managed switch with SFP ports for fiber uplink, for distribution points in multi-site networks, for installations where low power consumption and silent operation are priorities, and for MikroTik-managed environments where switching and routing flexibility on a single compact device is a key requirement.
