The MikroTik CRS309-1G-8S+IN is a desktop switch with eight 10G SFP+ ports and one Gigabit Ethernet port, dual-booting RouterOS or SwOS.

RouterOS (level 5) adds routing and Layer 3 features; SwOS keeps it a simple managed switch. The Gigabit port accepts 802.3af/at PoE-in, so a PoE switch can power it, and there is also a DC jack. MikroTik rates the switching capacity at 162 Gbps, with 81 Gbps non-blocking throughput.

Key features

  • 8 x SFP+ ports (up to 10G)
  • 1 x 10/100/1000 Ethernet port with 802.3af/at PoE-in, 18-57 V
  • Dual-core 98DX8208 CPU at 800 MHz, 512 MB RAM
  • DC jack 12-57 V, 23 W maximum
  • Fanless, RS232 serial console, 272 x 191 x 44 mm

In the box

  • 24 V 1.2 A power adapter
  • Ears
  • K-37 fastening set
