This chapter contains information to help you solve problems. If the Switch is not functioning properly, make sure the
Ethernet Switch was set up according to instructions in this manual.
How to let my non IEEE 802.3af network devices can work with POE-400?
Solution:
You can use PLANET Power over Ethernet Splitter, such as PLANET POE-152S to work as a power
transformer between POE-400 and non IEEE 802.3af devices. Two types of POE-152S are available
for different voltage, 5V DC and 12V DC.
The PoE LED is not lit
Solution:
Check the cable connection between POE-400 and IEEE 802.3af device.
Why I connect my PoE device to POE-400 and it cannot power on?
Solution:
1. Please check the cable type of the connection from POE-400 to the other end. The cable should
be an 8-wire UTP, Category 5/5e, 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.
