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

Watch out

  • The QSW-3205-5T's five ports are all 10GBASE-T; the QSW-2104-2T-R2 has only two 10G ports.
  • There is no SFP+ version of the QSW-3205-5T; for fiber uplinks look at the QSW-2104-2S.

Why people pick it

  • All 5 ports are 10GBASE-T, so a NAS and several PCs all get 10G over standard copper cabling
  • 100 Gbps switching capacity with 50 Gbps non-blocking throughput
  • Fanless design for silent desk placement
  • Every port auto-negotiates 10G/5G/2.5G/1G/100M for mixed-speed devices
  • Plug and play, with network loop detection

Know before you buy

  • Only 5 ports, and none slower than RJ45 copper: no SFP+ fiber option
  • Unmanaged: no VLANs, link aggregation or monitoring
  • 36 W maximum power draw is higher than 2.5G-only switches
  • External 12V power adapter rather than an internal supply
