Managed L3 switch MikroTik CRS310-8G+2S+IN — 8× 2.5G RJ-45, 2× SFP+, PoE, 1U rack-mount, White

The CRS310-8G+2S+IN is a compact switch that combines eight 2.5 Gigabit Ethernet ports with two 10 Gigabit SFP+ ports that also support 1G and 2.5G speeds. It uses a Marvell 98DX226S switch chip and an integrated dual-core ARM CPU running RouterOS v7, enabling VLANs, Jumbo frames, link aggregation, ACL rules and partial hardware-offloaded Layer‑3 routing. Multiple mounting options are available, including standard 19” rack mounting with included ears or an optional RMK-2/10 accessory for two-unit 1U mounting or 10” rack installation.

Advantages

The CRS310-8G+2S+IN provides a mix of multi-rate SFP+ flexibility and high-density 2.5G copper ports in a single compact chassis. The Marvell switch chip and dual-core CPU allow advanced Layer‑2 features and some hardware‑assisted Layer‑3 tasks while running RouterOS v7. Multiple mounting choices and standard rack ears included simplify installation in different rack environments.

Key specifications

• Ports: 8 × 2.5 Gigabit RJ45, 2 × 10 Gigabit SFP+ (supports 1G / 2.5G / 10G)
• Switch chip: Marvell 98DX226S
• CPU: integrated dual-core ARM
• Operating system: RouterOS v7
• Layer features: VLAN, Jumbo frames, link aggregation, ACLs, hardware-offloaded Layer‑3 routing (partial)
• Mounting: included 19” rack ears; optional RMK-2/10 for two-unit 1U or 10” rack mounting

How to use

Install the CRS310-8G+2S+IN in a rack using the supplied 19" ears or the RMK-2/10 accessory for alternative mounting. Connect copper devices to the 2.5G RJ45 ports and use SFP+ ports with compatible transceivers for 1G, 2.5G or 10G uplinks. Configure RouterOS v7 via the web interface, Winbox or CLI to set up VLANs, link aggregation, ACL rules and routing as required. Monitor performance and adjust settings to match network load and topology.

Recommendations

Use certified SFP/SFP+ transceivers and quality Cat5e/6 cabling for reliable 2.5G and 10G links. For full throughput with multiple high-speed flows, enable hardware offload features in RouterOS and plan VLANs and aggregation according to traffic patterns.
