DESCRIPTION

 

 

 

 

 

 

 

 

LED Status

 

This is the current LED indicator display – green, red, or yellow. The LED

 

 

Indicators

 

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).
