CRS305-1G-4S+IN: Five-port desktop switch with one Gigabit Ethernet port and four 10Gbps SFP+ ports

The CRS305 is a compact yet very powerful switch, with four SFP+ ports, providing up to 10 Gbit per port. The device has one 1 Gbit copper ethernet port for management access or regular traffic forwarding and two DC jacks for power redundancy. The device comes in a very sleek and compact metallic case without any fans, ensuring silent operation.

The device features a "Dual boot" function, allowing you to choose between two operating systems - RouterOS or SwOS. If you prefer a simplified operating system with only switch-specific functions, use SwOS. If you want the ability to use routing and other Layer 3 features in your CRS, use RouterOS. You can select your desired operating system from RouterOS, SwOS, or the RouterBOOT loader settings. The entire feature set comes at a disruptive price, providing the best price/performance on the market.
