1. Please check the POE-151S is connect with an IEEE 802.3af complied in-line device like POE-150, and check if the POE LED indicator at POE-151S is steady blink once attach to the IEEE 802.3af in-line power device. Then connect the DC plug cable to the device you would like to power on.
2. Please check the cable type of the connection from one end to the other end. The cable should be an 8-wire UTP, Category 5 or above, EIA568 cable within 100 meters. A cable with only 4-wire, short loop or over 100 meters, all will affect the power supply.
3. Please check the power requirement of the device you would like to power and check the label of the POE-151S if it meets the requirement. There are three models of POE-151S for different power output, DC 5V, DC 9 V and DC 12V.
4. Please check the specification of the powered device. If the device is over the specification of POE-151S, the LED indicator of POE-151S will blink instead of stead green. The maximum currents that POE-151S can supply are: 2A (5V DC), 1.3A (9V DC) and 1A (12V DC).
