What is the MikroTik CRS510-8XS-2XQ-IN?

It is a versatile switch from MikroTik’s 100 Gigabit family, designed for those who need high-speed connectivity without replacing the entire infrastructure. The device integrates a Marvell Prestera (98DX4310) chip that handles VLAN traffic, ACLs, MLAG, and jumbo frames, also offering L3 hardware offloading. Its architecture allows direct connection of 40G, 25G, 10G, and 1G devices, making it suitable for data centers and server rooms where different hardware generations coexist.

What are the main technical features?

The key specifications of the CRS510-8XS-2XQ-IN include:

  • Ports: 2x 100 Gigabit QSFP28, 8x 25 Gigabit SFP28, 1x 100M Ethernet port (console).
  • Processor: QCA9531 at 650 MHz (MIPSBE architecture, 1 core).
  • Memory and Storage: 128 MB RAM, 32 MB Flash.
  • Operating System: RouterOS v7 with a level 5 license.
  • Power Supply: Dual AC hot-swap power supplies (100-240 V), PoE-in input (43-57 V Passive PoE or 802.3bt Class 6), DC jack (36-57 V), and 2-pin terminal (36-57 V).
  • Power Consumption: Maximum 31 W without accessories, 51 W under full load.
  • Dimensions: 320 x 185 x 44 mm.
  • Operating Temperature: From -40°C to +70°C.

Who is it for and in which scenarios does it make sense?

This switch is ideal for network administrators who need to expand uplink capacity or aggregate traffic from high-density servers and access points. It makes sense in environments where you want to maintain compatibility with existing DAC, AOC, or RJ45 copper cables, avoiding additional costs for adapters. The presence of multiple power supply options makes it suitable even for installations where power redundancy is critical but space is limited.

What to know before choosing it?

You must consider that maximum power consumption rises to 51 W when all ports are active and powered, so ventilation and power supply must be sized accordingly. The device includes two power cables, rack ears, and a mounting kit in the box. The extreme operating temperature (-40°C) makes it usable even in unconditioned environments, but you need to verify that the SFP28 ports support the specific modules you intend to use, as compatibility depends on the inserted transceivers.
