IEN-8428P is an unmanaged PoE+ switch. It is built with industrial-grade components, enclosed in IP30 aluminum casing, and designed to withstand vibration, shock, free fall, and temperatures ranging from -40°C to 75°C.  With two 100FX/Gigabit SFP ports, the switch can be configured for fiber-based daisy chain topology to offer secure, reliable, and long-distance Gigabit connectivity.


 Robust Electrical and Electromagnetic Safeguard
Engineered to withstand EMI (electromagnetic interference), ESD (Electrostatic discharge), power surge, over voltage, over current, and reverse polarity.

 High-Power Budget for PoE Devices
Up to 30W per port powering to IEEE 802.3af PoE and IEEE 802.3at PoE+ devices. 

 Redundant Power System
Powered simultaneously with two different power sources, e.g. SDR-480P-48 power supply and IRA-120/IRA-160 DIN-rail mountable AC to DC power adapter, with power failure alarm.

 Advanced QoS Support
QoS (Quality of Service) for efficient bandwidth utilization and Storm Control for transmission at a predefined rate.

 Eco-friendly Green Ethernet Technology
IEEE 802.3az Energy Efficient Ethernet (EEE) compliant with Green Ethernet technology.
