Detection Failure Codes:
1. Incorrect resistive signature – The green “CONNECT” and green “PoEPLUS” LEDs
will blink 3 times.
2. Incorrect capacitive signature – The green “ON” LED will blink 3 times.
3. Incorrect Voffset – The green “CONNECT” and green “ON” LEDs will blink 3
times.
4. Unstable current measurement – The green “CONNECT” LED will blink 3 times
5. Low voltage sensed during detection (overload) – The green “PoE PLUS” LED will
blink 3 times
After the LEDs blink 3 times the PSE will continue to try to detect a valid load.
Therefore, until the correct load is applied, the LEDs will continue to blink. If there is an
open circuit connected to the output RJ45 then the LEDs will not blink but the PSE will
continue to try to detect a valid load.
Fault Sequence:
Should there be a fault such as an overload or short circuit then all the three LEDs will
blink 5 times in 2 seconds, and then go off as the power supply tries to re-detect a valid
load. If there is a problem in detecting, the LED will indicate what is wrong with the
load as per the codes in the section above.
