■ 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

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.
