The MikroTik CRS304-4XG-IN is a compact fanless switch with four 10G Ethernet ports and a Gigabit management port.

The enclosure doubles as the heat sink, so it runs silently. It has four power inputs (two DC jacks, a 2-pin terminal and 802.3af/at PoE-in) and uses whichever source has the highest voltage. A DIN rail mount is included, and it can dual-boot RouterOS v7 or SwOS.

Key features

  • 4 x 1G/2.5G/5G/10G Ethernet ports
  • 1 x 10/100/1000 Ethernet management port
  • Marvell 98DX2528 with dual-core ARM 64-bit CPU at 1.2 GHz, 512 MB RAM
  • Two DC jacks and a 2-pin terminal (12-57 V), plus PoE-in (36-57 V)
  • Passive cooling, 21 W maximum consumption
  • Rated for -40 to +70 °C

In the box

  • 48 V 0.95 A power adapter
  • Fastening set with DIN rail mount
