MikroTik CRS305-1G-4S+IN Gigabit Network Management Switch - Metal Casing - Redundant Power Supply - 10Gbps SFP+ Ports - RouterOS/SwOS

CRS305 has four SFP+ 10 Gigabit ports, each port is up to 10Gbps. There is also a Gigabit Ethernet port for management access to 2 DC jacks for power redundancy. The device is a very stylish and compact metal casing without any fan, achieving a silent effect.

The device has a "dual boot" feature that allows you to choose between two operating systems-Routeros or SwS. If you want to have a simplified operating system with only switch-specific functions, use SwOS. If you want to be able to use routing and other layer 3 functions in CRS, please use RouterOs. You can select the required operating system from RouterOS, SwOS or Router BOOT loader settings
