The MikroTik CRS305-1G-4S+IN is a compact fanless desktop switch with four 10G SFP+ ports and one Gigabit Ethernet port.

It dual-boots RouterOS (level 5) or SwOS: SwOS for plain switching, RouterOS when you need routing and other Layer 3 features. Two DC jacks give power redundancy, and the Ethernet port also accepts 802.3af/at PoE-in. SFP+ modules are not included.

Key features

  • 4 x SFP+ ports, up to 10 Gbps each
  • 1 x 10/100/1000 Ethernet port with PoE-in
  • Marvell 98DX3236 dual-core CPU at 800 MHz, 512 MB RAM
  • Two DC jacks and PoE-in, 12-57 V, 18 W maximum
  • Fanless metal case, 141 x 115 x 28 mm

In the box

  • 24 V 0.8 A power adapter
