7. TROUBLESHOOTING
This chapter contains information to help you solve your issue. If the PoE Web Smart Switch is not functioning properly, make
sure the PoE Web Smart Switch is set up according to instructions in this manual.
■ The Link LED is not lit
Solution:
Check the cable connection and remove duplex mode of the PoE Web Smart Switch
■ Some stations cannot talk to other stations located on the other port
Solution:
Please check the VLAN settings, trunk settings, or port enabled / disabled status.
■ Performance is bad
Solution:
Check the full duplex status of the PoE Web Smart Switch. If the PoE Web Smart Switch is set to full duplex and the partner is
set to half duplex, then the performance will be poor. Please also check the in/out rate of the port.
■ Why the Switch doesn't connect to the network
Solution:
1. Check the LNK/ACT LED on the PoE Web Smart Switch
2. Try another port on the PoE Web Smart Switch
3. Make sure the cable is installed properly
4. Make sure the cable is the right type
5. Turn off the power. After a while, turn on power again
■ 100Base-TX 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.
■ Switch does not power up
Solution:
 AC power cord not inserted or faulty
 Check whether the AC power cord is inserted correctly
 Replace the power cord if the cord is inserted correctly; check whether the AC power source is working by
connecting a different device in place of the switch.
