3.TROUBLESHOOTING
This chapter contains information to help you solve issues. If the POE-152 is not functioning properly, make sure the
POE-152 was set up according to instructions in this manual.
The PoE LED is not lit
Solution:
Check the cable connection between POE-152 and IEEE 802.3af device.
Why I connect my PoE device to POE-152 and it cannot power on?
Solution:
1. Please check the cable type of the connection from POE-152 to the other end. The cable should
be an 8-wire UTP, Category 5/5e/6, 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.
10/100/1000Base-T port link LED is lit, but the traffic is irregular
Solution:
Check that the attached device is not set to dedicate full duplex. Some devices use a physical or software switch to
change duplex modes. Auto-negotiation may not recognize this type of full-duplex setting.
