Purchase links appear where the exact offer is verified. Confirm the named model, quantity and accessories before ordering.

Watch out

  • The -2T and -2S variants share the QSW-2104 name; -2T uses RJ45 for its 10G ports, -2S uses SFP+ fiber.
  • -R2 marks Revision 2, the current hardware revision; older listings may show the R1 version.

Why people pick it

  • Two 10GBASE-T RJ45 ports for a 10G NAS and PC over standard Cat6a copper cabling
  • Four 2.5GbE ports cover multi-gig devices without extra configuration
  • Fanless design for silent placement on a desk
  • 60 Gbps switching capacity with 30 Gbps non-blocking throughput
  • Plug and play, with network loop detection that blocks looped ports

Know before you buy

  • Unmanaged: no VLANs, link aggregation or monitoring
  • Only 6 ports, so it suits a small NAS-and-PC cluster rather than a whole rack
  • External 12V power adapter rather than an internal supply
  • Energy Efficient Ethernet works on the 2.5G ports only
