Check the cable connection between POE-1200P2 / POE-2400P4 and IEEE 802.3af device.

1.Please check the cable type of the connection from POE Injector Hub to the other end. The cable should be an 8-wire UTP, Category 5/5e, EIA568 cable within 100 meters. A cable with only 4-wire, short loop or over 100 meters, all will affect the power supply.

2.Please check and assure the device that fully complied with IEEE 802.3af standard.

3.The POE Injector Hub is a Mid-Span PSE device, please make sure the connected PD supports PoE power input via RJ-45 pin 4/5(+), 7/8(-). If the connected PD supports power input only from 1/2(+), 3/6(-), it will not be powered on.
