Compact Layer 3 Switch for Small Networks

The Mikrotik CRS112-8G-4S-IN is a Cloud Router Switch designed for small office or home networks needing both switching and routing. It provides eight Gigabit Ethernet ports and four SFP cages for fibre uplinks. The unit runs RouterOS Level 5, offering a full Layer 3 feature set in a compact desktop form factor.

Desktop Placement with Flexible Power

Measuring 200x143x44 mm, the switch fits easily on a shelf or desk without a rack. It accepts passive PoE input at 10-57 V, allowing power delivery over the Ethernet cable and removing the need for a separate power adapter. Ports can be moved between the hardware switch chip and the CPU for either pure switching or routing duties.

Step Up from Basic Unmanaged Switches

This model replaces simple unmanaged switches when VLANs, static routing or bandwidth management are required. The 400 MHz CPU and 128 MB RAM handle RouterOS functions for networks that have outgrown plug-and-play gear. Buyers who need 10 GbE ports or higher port density should consider larger CRS models.
