Be sure the twisted pair cable is bound with the standard RJ-45 pin. 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.
