SEN-9428P-24V-SS is an unmanaged substation certified PoE+ switch with eight 10/100/1000Base-T ports and 4 Gigabit SFP slots. 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. 

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
IEEE 802.3at standard PoE+ with 240W total power budget for the whole system and various plug-n-play 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.
Fiber Connectivity with Dual SFP Ports
Dual Gigabit SFP ports for expansion of fiber-based daisy chain topology.
