Introduction

nnnn

The EKI-2525/2528 supports a Fast Ethernet solution. The power is a +12 - 48 VDC redundant input design, and is secured with a double protection mechanism: Power Polarity

nnnn

Reverse Protect and an Overload Current Resetable Fuse. The former tolerates reverse power wiring whilethe later secures the system from overload currents. As the power supply turns

nnnn

normal, EKI-2525/2528 will automatically get back to work. Each port of EKI-2525/2528 has 2 LED'stoshowthe link status transmission speed and collision status. It also provides

nnnn

a relay output for an event alarm. In the event of a power failure, the built-in LED will activate the alarm to notify administrators. Engineers can simply verify the hardware status by

nnnn

checking the LED, and have troubleshooting easy and quick. EKI-2525/2528 comes with compact metal housing that rates IP30 to help against from dusty industrial environments.
