PoE Network Switches


Hardened Grade Unmanaged 8-port 10/100/1000Base-TX (PoE+) + 2-port 1000Base-SFP Ethernet Switch

Main Features -

Fault Alarm (via electric relay)

  • The built-in fault alarm function sends out alert via the electric relay when there’s fault on the network switch.
  • It helps measure performance and quickly find out anomalies of the network switch.

Full loading Power Budget

  • The ET8222PpH-S-DR provides a quick, safe and cost-effective IEEE802.3af/at PoE network solution for various enterprises and infrastructures.
  • It supports up to 8-port 30-watt per port output, possessing a high loading power budget of up to 240 watts for different kinds of heavy PoE applications.

Dual Power Input for High Reliability

  • Automatically switch to secondary power input when primary power input fails, ensuring continuous operation without down time.
  • Redundant power supply reduces possibility of single-point-of-failure.

Environmentally Hardened Design

  • With a compact metal housing with an IP40 rating
  • Environmentally hardened for direct deployment in difficult unconditioned out-of-plant and roadside installations.
  • Extended ambient operating temperature range: -40 ̊ C to +75 ̊ C
