■ Why the PoE Ethernet Switch doesn't connect to the network
Solution:
Check the LNK/ACT LED on the PoE Ethernet Switch. Try another port on the PoE Ethernet Switch. Make sure the cable is
installed properly and make sure the cable is the right type. Turn off the power. After a while, turn on power again.
■ When I connect my PoE device to PoE Ethernet Switch, it cannot be powered on
Solution:
1. Please check the cable type of the connection from the PoE Ethernet Switch (port 1 to port 8) 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 will affect the power supply.
2. Please check and assure the device is fully complied with IEEE 802.3af/802.3at standard.
