LEDS
The LEDs in the unit indicate status of the Ethernet Power
Supply and its ports.
A main power LED on the front panel, marked by AC,
provides the Ethernet Power Supply status. The "AC" LED
illuminating green indicates that the Ethernet Power Supply is
connected to an AC outlet. The AC LED illuminating orange
indicates an internal fault. See tables 2 and 3.
One bi-color LED (green and orange) per port provides port
status. The green color indicates that the terminal unit has been
identified as "Power Over LAN enabled" and is active and
receiving power.
The orange LED indicates the port is not supplying power and
is not active. See Table 1 for additional information.
NOTE: In the event that an Ethernet device that is not Power
Over LAN enabled is connected to the Ethernet Power Supply
(indicated by the orange color or off), the Ethernet device is
unaffected because power is not being supplied.
