• The CRS305 is a compact yet very powerful switch, featuring 4 SFP+ ports, for up to 10 Gbit per port.
  • It has a 1 Gbit copper ethernet port for management access and 2 DC jacks for power redundancy.
  • The device is a very sleek and compact metallic case without any fans, for silent operation.
  • It also has a “Dual boot” feature that allows you to choose between 2 operating systems (RouterOS or SwOS).
    -If you prefer to have a simplified operating system with only switch specific features, use SwOS.
    -If you would like the ability to use routing and other Layer 3 features in your CRS, use RouterOS.
