 Why the LCD Switch cannot power on the PoE device
Solution:
1. Please check the cable type of the connection from LCD switch to the other
end. The cable should be an 8-wire UTP, Category 5 or above and EIA568 cable
within 100 meters. A cable with only 4-wire, short loop or over 100 meters will
affect the power supply.
2. If the PoE device is fully complied with IEEE 802.3bt standard, please set the
LCD switch as 802.3bt mode, and then connect the PoE device to port 1 to port
4 of LCD switch.
3. If the PoE device is not fully complied with IEEE 802.3bt standard, please set
the LCD switch as UPoE/Legacy mode, and then connect the PoE device to port
1 to port 4 of LCD switch.
4. If the PoE device is fully complied with IEEE 802.3af/at standard, please connect
the PoE device to port 5 to port 16 of LCD switch.
