5. Troubleshooting
This chapter contains information to help you solve issues. If the PoE Fast Ethernet
Switch is not functioning properly, make sure the PoE Fast Ethernet Switch was set
up according to instructions in this manual.
The Link LED is not light
Solution:
Check the cable connection and remove duplex mode of the PoE Fast Ethernet
Switch.
Performance is bad
Solution:
Check the full duplex status of the Switch. If the PoE Fast Ethernet Switch is set to
full duplex and the partner is set to half duplex, then the performance will be poor.
100Base-TX port link LED is light, 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.
Why the Switch doesn’t connect to the network
Solution:
Check the LNK/ACT LED on the switch Try another port on the PoE Fast Ethernet
Switch Make sure the cable is installed properly Make sure the cable is the right
type Turn off the power. After a while, turn on power again.
Why connects PoE device to FNSW-1600P and it cannot power on?
Solution:
Please check the cable type of the connection from FNSW-1600P 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, all will affect the
power supply.
Please check and assure the device that fully complied with IEEE 802.3af standard.
What is the power output of each IEEE 802.af PoE port?
Solution:
Each PoE port supports 48V DC, 350mA, max 15.4 Watts power output. Detect
and inject by the standard of IEEE 802.3af.
