MikroTik Cloud Router Switch CRS309-1G-8S+IN, 1x GB Ethernet, 8x SFP+ Cages, RouterOS L5 Or SwitchOS (Dual Boot), Passive Desktop Case, PSU
Description
The CRS309-1G-8S+IN boasts eight SFP+ slots, each supporting up to a 10 Gbit module. This configuration results in an impressive switching capacity of 162 Gbps and a total non-blocking throughput of 81 Gbps. Remarkable capability like this ensures your network can easily manage demanding tasks. Equipped with a dual-core 800 MHz CPU and 512 MB of RAM, the CRS309-1G-8S+IN is built to smoothly manage data-intensive operations.
This hardware combination ensures efficient data processing, allowing for optimized network performance even during periods of high demand or peak loads. The switch's ability to handle dual boot lets you choose between RouterOS and SwOS operating systems, adapting to your network's specific needs. Opt for SwOS if you prefer a streamlined interface focused on switch-specific functions or go for RouterOS to tap into advanced routing.
The CRS309-1G-8S+IN features a sleek metallic case that also acts as a heatsink. This passive cooling design eliminates fan noise and prevents dust accumulation inside the switch, resulting in reliable and maintenance-free operation. For added convenience, the package includes special rackmount ears, enabling easy installation in standard racks.
The switch offers a diverse range of connectivity options to suit various scenarios. With one dedicated Gigabit Ethernet port and eight high-speed SFP+ ports, your network can seamlessly accommodate different devices and applications.
Additionally, the CRS309-1G-8S+IN supports multiple power input methods, including AC/DC adapters, various passive PoE standards, and 802.3af/at PoE. This flexibility makes the deployment process more convenient and adaptable to various networking setups.
