The MikroTik CRS309-1G-8S+IN is a versatile network switch designed to handle high-bandwidth traffic through its eight SFP+ ports, each supporting speeds up to 10 Gbit. This capacity is backed by a total switching capacity of 162 Gbps and a non-blocking throughput of 81 Gbps, making it a reliable choice for environments where fast data transfer is essential. For administrative tasks, it includes a dedicated 10/100/1000 Mbps Ethernet management port that also supports PoE power input, alongside an RS232 serial port for direct console access. Under the hood, the device runs on a dual-core 800 MHz CPU with 512 MB of RAM, offering the flexibility of a dual-boot system that lets you choose between RouterOS and SwOS depending on your configuration needs. The white chassis measures 272 x 191 x 44 mm and is built to operate in extreme conditions, with a temperature range from -40 °C to 70 °C. It can be placed on a desktop or installed in a rack using the included ears, while power is supplied via a DC jack or the management port within a 12-57 V range. To ensure stability and safety, the unit features a grounding terminal, a CPU temperature monitor, and helpful LED indicators.
