*PD Port Wiring
Port 1 to 4 provides PoE injection function with maximum 35W ability to power up the powered device
using the straight-through or cross-over Ethernet cable.
The PoE switch follows the IEEE802.3af Alternative B mode connector assignment. The following table
shows pin assignment of alternative A and B for the Power Source Equipment.

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.
