LABEL DESCRIPTION
LED Status
Indicators
This is the current LED indicator display – green, red, or yellow. The LED
indicator changes depending on the status of the connected PoE-enabled
device.
Green: The PoE-enabled device is connected to the port and functioning
properly.
Red: Error, the PoE-enabled device connected to the port needs more power
than the PoE-80 can provide or the Ethernet cable has shorted.
Yellow: No PoE-enabled device is connected to the port.
Fault Status
This displays the status (Null, Overload or DR Fail) of the connected PoE-
enabled device that the system has detected.
Null: No PoE-enabled device is connected to the port.
Overload: The current went higher than 475mA @48V DC for more than 50
milliseconds.
DR Fail: The PoE-enabled device’s discovery resistor is not within the range
defined in IEEE 802.3af (19,600 to 26,500 Ohm).
Mode Status
This displays the status (I sample, V sample or R detect) of the connection to
a PoE-enabled device.
I sample: The PoE-80 is sending current to detect whether or not the PoE-
enabled device is still connected to the port.
V sample: The PoE-80 is sending voltage to detect whether or not the PoE-
enabled device is still connected to the port.
R detect: The PoE-80 is trying to detect the resistor of a PoE-enabled device
(the port is not connected to a PoE-enabled device).
