Power-up Sequence:
Detection Sequence:
Fault Sequence:
Upon power-up, all 3 LEDs will light for 2 seconds, as part of the self-test for the internal microprocessor
software. After the end of the 2 seconds, the "ON" LED will illuminate green, signifying that the DC output
voltage is available for powering a compliant load (to the 802.3at PoE standards).
Once a compliant load is attached to the output RJ45 connector, the green "CONNECT" LED will illuminate.
Should the load is classified as Class 4 PD, the green “PoEPLUS” LED will illuminate. Otherwise, “PoEPLUS”
LED will stay off.
Should the load be non-compliant then the LEDs will blink a code signifying the cause for non-detection.
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.
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.
