  • Extend & VLAN‑isolation mode — optional long‑distance 10 M / 250 m transmission on access
    ports with port isolation for simple segmented networks
  • Uplink flexibility — dual RJ45 uplinks; 1× SFP (1000BASE‑X) on 8P‑1S model for fiber backhaul
  • Wire‑speed switching with store‑and‑forward and jumbo‑frame support (model‑dependent)
  • Industrial‑grade protection — 4 kV lightning protection, IP30 enclosure
  • Wide temperature operation −20 to +55 °C, fanless designs
  • Desktop / Wall‑mount options; compact metal chassis
