MikroTik CRS310-8G+2S+IN 8-Port 2.5G 2x10G SFP+ Managed Switch

The MikroTik CRS310-8G+2S+IN is a compact, fan-cooled Layer 3 managed switch designed for small offices and edge deployments that are moving beyond standard Gigabit infrastructure. It delivers eight 2.5 Gigabit Ethernet ports alongside two 10 Gigabit SFP+ uplink ports, all driven by a dual-core 98DX226S ARM 32-bit processor running at 800 MHz. The SFP+ cages are multi-rate capable, supporting 1G, 2.5G, and 10G transceivers, giving network engineers the flexibility to deploy the unit as a 10-port 2.5G switch when the application demands it. The switch runs MikroTik RouterOS v7 or SwitchOS under a RouterOS License Level 5, providing a broad set of Layer 3 routing and switching features in a 200 × 206.1 × 44 mm chassis. DC jack input accepts 18–57 V, and the unit ships with a 24V 1.5A power adapter, rack-mounting ears, and a K-48 fastening set. With an IP20 rating and a tested ambient operating range of −40 °C to 60 °C, it is suited for controlled indoor environments including wiring closets, compact server rooms, and densely deployed edge sites.

Key features & benefits

• Eight 2.5G Ethernet Ports — All eight copper ports operate at 2.5 Gigabit, delivering a significant throughput increase over legacy Gigabit infrastructure without requiring a full 10G cabling investment.
• Dual 10G SFP+ Uplinks with Multi-Rate Support — The two SFP+ cages support 1G, 2.5G, and 10G data rates, allowing the unit to serve as a 10-port 2.5G switch or connect to 10G core and aggregation equipment using the same physical ports.
• Layer 3 Management via RouterOS v7 and SwitchOS — RouterOS License Level 5 and dual-OS support give administrators access to advanced routing, VLAN, ACL, and switching features through a single platform.
• Dual-Core ARM Processor — The 98DX226S dual-core ARM 32-bit CPU running at 800 MHz serves as both the switch chip and the management processor, consolidating the data and control planes in a compact design.
• Wide DC Input Voltage Range — The DC jack accepts 18–57 V, making the switch compatible with a variety of DC power sources and suitable for deployments alongside PoE injectors, DC UPS systems, and distributed power architectures.
• Extended Ambient Temperature Range — Tested and rated from −40 °C to 60 °C, the switch maintains reliable operation across demanding indoor environments where temperature control may be limited.
• CPU and PCB Temperature Monitoring — Onboard thermal monitors for both the CPU and PCB allow administrators to track thermal health in real time and respond proactively to environmental changes.
• USB Type-A Port with Power Reset — A single USB Type-A port delivering up to 1 A supports peripheral attachments and USB Power Reset functionality, adding flexibility for remote management accessories and storage.
• Compact, Fan-Cooled Chassis — The 200 × 206.1 × 44 mm enclosure with a single active cooling fan balances high port density with a small physical footprint, fitting standard rack mounting with the included ears.
• CE, EAC, and RoHS Certified — Third-party certifications confirm electromagnetic compliance and restriction of hazardous substances, supporting deployment in regulated enterprise and commercial environments.
