Compact five-port desktop switch

The Mikrotik CRS305-1G-4S+IN is a fanless desktop switch built for quiet environments. It provides four SFP+ ports operating at 10 Gbit per port and one Gigabit Ethernet port for management access. The metallic enclosure houses dual DC jacks for power redundancy. It suits home labs or small offices needing silent 10G connectivity.

Dual-boot OS and SFP+ flexibility

The switch runs either RouterOS Layer 5 or SwOS, selectable from the bootloader or the running system. RouterOS adds routing and Layer 3 features while SwOS focuses on switching functions. Four SFP+ cages accept compatible transceivers or direct-attach cables for fibre or copper uplinks. The single copper port remains available for out-of-band management.

Silent operation under sustained load

With no moving parts the unit stays silent regardless of traffic volume. The passively cooled metal chassis dissipates heat during continuous 10 Gbit throughput on all SFP+ ports. Dual power inputs keep the switch running if one supply fails. It is not suited for builds requiring PoE, additional copper ports or rack-mount brackets.

  • Four SFP+ ports deliver 10 Gbit connectivity
  • Silent fanless metal case suits quiet environments
  • Dual DC jacks provide power redundancy
  • Dual boot selects RouterOS or SwOS
