MikroTik CSS318-16G-2S+IN — Managed Switch for Small and Medium Businesses

MikroTik CSS318-16G-2S+IN is a compact managed switch with 16 Gigabit Ethernet ports and 2 SFP+ 10G ports, designed for small and medium offices, home networks, and rackmount environments where 8 ports are not enough but 24 is an unjustified excess. It is deployed by network administrators and integrators looking for an energy-efficient managed switch that is simple to configure and flexible in terms of mounting, without the complexity and cost of large enterprise switches. The compact 10-inch form factor allows mounting in 10-inch racks, standard 19-inch racks, or side-by-side — two units in a single 1U 19-inch rack space.

The switch features 16 Gigabit Ethernet ports for local network connectivity and 2 SFP+ 10G ports for high-speed uplinks to NAS servers, core equipment, or fiber connections. The 98DX2518 switch chip delivers stable and high-performance switching across all ports simultaneously, while passive cooling eliminates fan noise and moving mechanical components for long-term reliability. A consumption of just 10W idle and 13W at full load keeps energy costs minimal in permanent installations.

Configuration is handled via SwOS accessible directly from the browser without additional software, providing the core functionality of a managed switch: port-to-port forwarding, broadcast storm control, MAC filtering, VLAN configuration, traffic mirroring, bandwidth limitation, and adjustment of MAC and IP header fields. The CSS318-16G-2S+IN includes an internal AC 100–240V power supply, eliminating the need for an external adapter, and the operating range from -40°C to +70°C ensures reliability across diverse installation environments.

Recommended for small and medium offices needing more than 8 managed ports without the cost and size of a 24-port switch, home offices and studios with 10G uplinks for NAS or high-performance workstations, and rackmount environments where port density and rack space efficiency are priorities. Also suited for expanding existing networks by mounting two CSS318 units side-by-side in a single 1U slot, and for any deployment where SwOS configuration simplicity and low power consumption are decisive factors.
