*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.
*Network Application
The PoE Switch can receive power from a PoE midspan and provide power to the PD which
follows the IEEE 802.3af/at standard in the network. The PoE Switch can be installed in a more
appropriate position for better performance to extend Ethernet to 200 meters. The following figure
is an example of a network application for the PoE Switch.
