MikroTik CSS318-16G-2S+IN 16-Port Gigabit Cloud Smart Switch with 2x 10G SFP+

MikroTik CSS318-16G-2S+IN 16-Port Gigabit Cloud Smart Switch with 2x 10G SFP+

The MikroTik CSS318-16G-2S+IN is a compact and cost-effective Cloud Smart Switch designed for small and medium-sized networks that need more than 8 ports but do not require a full 24-port switch. With 16 Gigabit Ethernet ports and 2 SFP+ 10G uplink ports, it provides an efficient balance of copper connectivity, fiber expansion, and rack-friendly installation options.

Built around MikroTik’s lightweight SwOS operating system, the CSS318-16G-2S+IN offers essential Layer 2 switching features through a simple web interface. It is ideal for offices, home labs, small business networks, fiber uplinks, rack cabinets, and network environments where compact size and reliable switching matter more than unnecessary bulk.

The CSS318-16G-2S+IN features a compact 10-inch form factor and can be installed in 10-inch racks, standard 19-inch racks, or mounted side-by-side with another unit in a single 1U 19-inch rack space. MikroTik designed it for flexible installations where space efficiency is not just nice to have, but the difference between a clean cabinet and cable soup.

• Ideal for SMB, home office, lab, and fiber uplink deployments

Compact 16-Port Switching

The CSS318-16G-2S+IN is designed for deployments where an 8-port switch is too limited and a 24-port switch is larger than necessary. Its 16 Gigabit Ethernet ports provide practical wired connectivity for desktops, access points, cameras, printers, VoIP phones, and other network devices.

10G SFP+ Uplink Flexibility

The two SFP+ ports support high-speed 10G uplinks for fiber backbone connections, aggregation switches, servers, NAS devices, or ISP handoffs. This makes the CSS318-16G-2S+IN a strong fit for networks that need affordable Gigabit access switching with room for high-speed expansion.

Simple SwOS Management

MikroTik SwOS provides a lightweight web-based management interface for essential switch configuration. Administrators can configure VLANs, port isolation, link monitoring, traffic forwarding, port mirroring, and other Layer 2 features without the complexity of a full routing operating system.

Flexible Rackmount Design

With its compact 10-inch design, the CSS318-16G-2S+IN can fit into smaller rack cabinets while still supporting standard 19-inch rack installations. For higher port density, two CSS318 units can be installed side-by-side in one 1U rack space, making it a neat option for scalable SMB or lab environments.

Ideal Applications

• Small and medium business networks
• Home office and advanced home networks
• Network cabinets with limited rack space
• Fiber uplink and 10G backbone deployments
• NAS, server, and lab environments
• Access switching for cameras, access points, printers, and workstations
• Affordable managed Layer 2 switching with SwOS
