## Long description

The MikroTik CRS309-1G-8S+ is a compact managed desktop switch with one Gigabit Ethernet RJ‑45 port and eight SFP+ slots supporting up to 10 Gbps per port. It offers a total switching capacity of 162 Gbps and non‑blocking throughput of 81 Gbps, and includes a dual‑core 800 MHz CPU, 512 MB RAM, an RS‑232 console port, a grounding terminal and a management Ethernet port with PoE input. The device supports dual boot, allowing selection between RouterOS and SwOS.
Advantages
The switch delivers high port density for 10G SFP+ connectivity in a compact desktop form factor while maintaining non‑blocking performance. Built‑in management features, an RS‑232 console and a dedicated management Ethernet port with PoE input simplify installation and administration. Dual‑boot capability provides flexibility to choose RouterOS for advanced routing features or SwOS for simple switch management.

How to use
Install the CRS309‑1G‑8S+ on a stable surface in a ventilated area and connect power using a compatible DC source (12–57 V) or provide PoE to the management Ethernet port if supported by your infrastructure. Insert compatible SFP+ modules into the SFP+ slots and connect the Gigabit RJ‑45 port as required. Access the device via the management Ethernet port or the RS‑232 console to configure network settings, choose the preferred boot OS (RouterOS or SwOS) and apply VLANs, link aggregation or other managed switch features.
Usage recommendations
Use quality SFP+ modules and appropriate fiber or DAC cables rated for 10 Gbps to ensure full performance. Maintain adequate ventilation and avoid stacking other heat‑generating equipment directly on top of the unit. Select RouterOS for advanced routing and filtering needs, or SwOS for simpler switch management.
