Safety Precaution - Static Electricity
Static electricity can cause bodily harm or damage electronic devices. To avoid dam-
age, keep static-sensitive devices in the static-protective packaging until the installa-
tion period. The following guidelines are also recommended:
Wear a grounded wrist or ankle strap and use gloves to prevent direct contact to
the device before servicing the device. Avoid nylon gloves or work clothes,
which tend to build up a charge.
Always disconnect the power from the device before servicing it.
Before plugging a cable into any port, discharge the voltage stored on the cable
by touching the electrical contacts to the ground surface.

3.2 LED Display Status
According to your operation environment and power allocation, the display status of
PoE Output LED will have three situations for EKI-1751PI-R-AE device.
1. When the PoE power voltage is above or equal 50V (>=50V), the PoE output is
normally working and LED display is stable status.
2. If the voltage between 44V and 50V, the PoE output is warning status and LED
display is blinking. The device will cut off PoE Output in port-2, port-3 and port-4
automatically to protect the device.
3. When detected under 44V low voltage (<44V), the PoE output is not working
and LED is off status.
