diagnostic led functions and schematic block diagram www.phihong.com 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 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 802.3af poe standards). 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 signifying the cause for non- detection. detection failure codes: 1. incorrect resistive signature ? the green ?c onnect? and red ?fault? leds will blink 3 times. 2. incorrect capacitive signature ? th e 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. 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 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 redetect 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.
