MikroTik CRS309-1G-8S+IN Cloud Router Switch

The MikroTik CRS309-1G-8S+ is a compact, yet powerful networking switch, with 8 x SFP+ slots, each capable of supporting up to a 10 Gbit module.

The CRS309-1G-8S+ has a total non-blocking throughput of 81 Gbps and a total switching capacity of 162 Gbps.

The CRS309-1G-8S+ features 512 MB RAM, a dual-core 800 MHz CPU, RS232 serial port, Management Ethernet port with PoE power input, grounding terminal, and is capable of dual boot (allowing you to choose either RouterOS, or SwOS as your preferred operating system).

The CRS309's compact and sleek metallic enclosure also acts as a heatsink, meaning that the device is passively cooled resulting in no fan noise or build up of dust inside the device.

Special rack-mount ears are provided for installing the CRS309-1G-8S+ into a standard rack.
