The MikroTik CRS520-4XS-16XQ-RM is a 1U rackmount switch with 16 x 100G QSFP28 ports, 4 x 25G SFP28 ports and two 10G Ethernet ports.

It uses the quad-core 2 GHz ARM CPU from the CCR range with 4 GB of DDR4 RAM, so it can also run OSPF/BGP, management VPNs and Layer 3 hardware-offloaded routing on RouterOS v7. Two hot-swap power supplies and four hot-swap fans are included. A -48 V DC telecom supply (PW48V-12V150W) is available separately.

Key features

  • 16 x QSFP28 ports (100G)
  • 4 x SFP28 ports (25G)
  • 2 x 10G Ethernet ports
  • Quad-core AL52400 CPU at 2 GHz, 4 GB RAM
  • Two hot-swap 100-240 V AC PSUs, four hot-swap fans
  • RJ45 serial console, 150 W maximum (220 W with both PSUs)

In the box

  • 2 x IEC power cords
  • Rack ears
  • Rear rack support ears
  • Cable management brackets
  • K-82 fastening set
