The MikroTik CRS310-8G+2S+IN is a compact Cloud Router Switch designed for networks upgrading from Gigabit to multi-gigabit Ethernet. With eight 2.5G Ethernet ports and two 10G SFP+ uplinks, it provides a practical access-layer solution for offices, labs, and edge deployments that need higher throughput without moving to full 10G on every port.

Where the CRS310-8G+2S+IN is commonly used

• Office and SMB access switching
• High-speed workstation and NAS connectivity
• Network labs and test environments
• Edge switching with 10G uplinks to core or aggregation switches

Powered by a Marvell switch chip and a dual-core ARM CPU, the CRS310-8G+2S+IN delivers reliable Layer 2 performance with support for VLANs, jumbo frames, link aggregation, ACLs, and hardware-offloaded routing where applicable. It supports RouterOS v7 for advanced control or SwOS for simplified switch-only operation.

The switch includes eight 2.5 Gigabit Ethernet ports for high-speed access connections and two SFP+ cages for uplinks. The SFP+ ports support multiple data rates, including 1G, 2.5G, and 10G, allowing flexible integration into existing network infrastructure or use as a fully multi-gigabit switch.

The CRS310-8G+2S+IN can be mounted in a standard 19-inch rack using the included rack ears. With optional mounting accessories, two units can be installed in a single 1U space or used in compact rack environments, making it suitable for space-constrained deployments.

• 8 × 2.5 Gigabit Ethernet ports
• 2 × 10G SFP+ uplink ports
• Multi-rate SFP+ support (1G / 2.5G / 10G)
• RouterOS or SwOS support
• VLANs, jumbo frames, link aggregation, ACLs
• Hardware-offloaded routing (select features)
