Introduction

The EKI-2525PA and EKI-2528PAI are 5/8-port unmanaged PoE industrial Ethernet switches with 4 PoE ports classified as power source equipment. These PoE switches realize a
centralized power supply, providing up to 15.4 W of power per port. Advantech EKI PoE switches can be implemented to power IEEE 802.3af-compliant powered devices via Ethernet
cable, thus eliminating the need for additional wiring. Advantech EKI PoE switches come equipped with all the standard features of the EKI family. Furthermore, they offer a 24/48
VDC redundant power input design and are secured with a double protection mechanism: power polarity reverse protect and an overload current resettable fuse. Advantech EKI PoE
devices come with an IP30-rated compact metal housing to protect against dust in industrial environments.
