Unmanaged Network Switches


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

Main Features -

IEEE 802.3bt PoE++ Solutions

  • The product adopts IEEE 802.3bt PoE++ standard technology, provides up to 95 watts per port output as an ideal solution for higher power consumption network PDs, such as POS system, digital signage.

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.

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
