IEN-8428P-24V 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.

The intelligent PoE+, compactable size, rugged design of IEN-8428P-24V ensure continuous operations in some special requirements for transportation, factory and outdoor places where high vibration degree, shock and wide range temperatures are present. Addition to this the dual Gigabit SFP ports which can easily make daisy chain topologies to power more number of PoE+ enable power devices as well as saves the amount of fiber cabling connecting to the control room. Due to daisy chain architecture only a single fiber connects to the control room which in turn saves CAPEX.

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. 

Innovative Power Boost Technology
24V to 57V DC power boosting with DC-to-DC converter for high-power requiring PoE/PoE+ devices
