Introduction
The EKI-3725/3728 are a new generation products with green Ethernet design. They feature green solutions that automatically adjust power consumption by detecting the link status
and cable length. Designed with 1/2 "VIP" ports to get optimal bandwidth for media traffics through VIP ports users can experience better performance of multimedia streaming
preferred through prioritized bandwidth setting. The devices come with compact metal and plastic housing that is IP40 rated to protect against dusty industrial environments. The wide
power input power (8.4 to 52.4 VDC) is dedicated to operate in areas of unstable power and rugged environments. It also provides an event alarm and in the event of a power failure
and connection loop, the intergrated LED will activate the alarm to notify administrators.
