Be sure the twisted pair cable is bound with the standard RJ-45 pin, especially the pins 4, 5, 7 and 8.
If the RJ-45 is bound with the wrong pin number, the PoE switch will not recognize the PD and
won’t deliver DC power to the PD. The yellow PoE LED will light up when the cable is correctly
connected. Refer to the
LED Indicator
section for descriptions of each LED indicator. If a port
LED is off, go back and check for connectivity problems between that port and the network device
connected.
