The MikroTik CRS310-1G-5S-4S+IN is a fibre switch with five 1G SFP ports, four 10G SFP+ ports and one Gigabit Ethernet port, mountable in a 1U rack.

It is the indoor version of the netFiber 9. The Marvell 98DX226S switch chip handles hardware-offloaded VLAN filtering and some Layer 3 routing, and it dual-boots RouterOS v7 or SwOS. The Ethernet port connects directly to the switch chip and accepts PoE-in as a second power source.

Key features

  • 5 x SFP ports (1G)
  • 4 x SFP+ ports (10G)
  • 1 x 10/100/1000 Ethernet port with 802.3af/at PoE-in
  • Dual-core ARM CPU at 800 MHz, 256 MB RAM
  • DC jack or PoE-in, 18-57 V, 20 W maximum
  • RJ45 serial console, one fan

In the box

  • 24 V 1.2 A power adapter
  • Rack ears
  • K-48 fastening set
