Introduction
The EKI-2728 supports Gigabit Ethernet and features a +12
to 48 VDC redundant power input design with dual protec-
tion mechanisms: Power Polarity Reverse Protection and
an Overload Current Fuse. The former allows for reverse
power wiring, while the latter protects the system from
overload currents. Each port of the EKI-2728 is equipped
with two LEDs to indicate link status, transmission speed,
and collision status. Additionally, the device includes a relay
output for event alarms. In case of a power failure, a built-in
LED activates to notify administrators. Engineers can easily
verify the hardware status by checking the LEDs, making
troubleshooting quick and simple.
