MikroTik CSS318-16G-2S+IN 16-Port Gigabit PoE Switch 2x 10G SFP+

The MikroTik CSS318-16G-2S+IN is a Cloud Smart Switch delivering 16 Gigabit Ethernet RJ45 ports and 2 SFP+ 10G uplink ports in a compact 10-inch form factor. Powered by MikroTik's SwOS operating system, it provides web-based Layer 2 management covering VLANs, port isolation, port mirroring, link monitoring, and traffic forwarding without the overhead of a full routing OS. Its passive cooling design enables completely silent operation, and a maximum power draw of 13W keeps energy costs minimal. The chassis fits natively into 10-inch rack cabinets, slides into standard 19-inch racks with appropriate hardware, and two units can be mounted side-by-side in a single 1U 19-inch rack space for efficient port density scaling. With an IP20 rating and a tested ambient operating range of -40°C to 70°C, the CSS318-16G-2S+IN is built for reliable continuous deployment in offices, network closets, home labs, and small-to-medium business environments where right-sized switching and clean cable management are priorities.

Key features & benefits

• 16 Gigabit Ethernet Ports — Sixteen 10/100/1000 RJ45 ports provide full-density copper connectivity for workstations, access points, IP cameras, VoIP phones, printers, and other wired network devices without overprovisioning port count.
• Dual 10G SFP+ Uplinks — Two SFP+ ports support 10-Gigabit uplinks for fiber backbone connections, aggregation switch handoffs, high-performance servers, and NAS devices, giving Gigabit-access networks a high-speed expansion path.
• SwOS Web-Based Management — MikroTik's lightweight SwOS operating system delivers a streamlined browser-based interface for VLAN configuration, port isolation, port mirroring, link monitoring, and traffic forwarding—essential Layer 2 control without routing-OS complexity.
• Compact 10-Inch Form Factor — The chassis is natively sized for 10-inch rack cabinets and also supports 19-inch rack installation. Two units fit side-by-side in a single 1U 19-inch rack space, maximizing port density in space-constrained enclosures.
• Passive Fanless Cooling — Completely passive thermal management eliminates fan noise, making the switch suitable for quiet office environments, audio-visual installations, and anywhere acoustic performance is a consideration.
• Low Power Consumption — Maximum power draw is rated at 13W under full load and 10W without attachments, reducing operating costs and heat load in densely populated rack environments.
• Wide Tested Temperature Range — Tested for operation from -40°C to 70°C, the switch maintains reliable performance across unheated server rooms, industrial-adjacent spaces, and variable-climate network closets.
• CPU Temperature Monitor — An onboard CPU temperature monitor allows administrators to track thermal conditions directly from the management interface, supporting proactive maintenance in enclosed rack deployments.
