Description of LED Functions for Gigabit Power Injector 
Power-up 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 2 second period, the "ON" LED will illuminate green. The DC 
output voltage is now available for powering a compliant load (Phihong Proprietary detetcion). 
 
Detection Sequence: 
 
Once a compliant load is attached to the output RJ45 connector, the green "CONNECT" LED will 
illuminate. 
 
Should the load be non-compliant then the LEDs will blink a code specific to the cause for non-
detection. 
 
 
Detection Failure Codes: 
1.  Incorrect resistive signature – The green “CONNECT” and red “FAULT” 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 “ON” LED will blink 3 times 
5.  Low voltage sensed during detection (overload) – The red “FAULT” LED will blink 3 times 
 
After the LEDs blink 3 times the Power Injector will continue to try to detect a valid load.  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 Power Injector will continue to try to detect a valid 
load.  
 
Fault Sequence: 
Should there be a fault such as an overload or short circuit then the red "FAULT" LED will illuminate.  
The red “FAULT” LED will illuminate for 2 seconds and then go off as the power supply tries to re-
detect a valid load.  If there is a problem detecting the load, the LED will indicate the possible fault as 
per the codes in the section above.
