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
