This chapter contains information to help you solve problems. If the Ethernet Switch is not functioning properly, make sure 

the Ethernet Switch was set up according to instructions in this manual. 

■  The Link LED is not lit 

Check the cable connection and remove duplex mode of the Ethernet Switch 

■  Some stations cannot talk to other stations located on the other port   

Please check the VLAN settings, trunk settings, or port enabled / disabled status. 

■  Performance is bad 

Check the full duplex status of the Ethernet Switch.    If the Ethernet 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 

1. 

Check the LNK/ACT LED on the switch 

2. 

Try another port on the 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 

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 

1. 

AC power cord not inserted or faulty 

2. 

Check that the AC power cord is inserted correctly 

3. 

Replace the power cord If the cord is inserted correctly, check that the AC power source is working by connecting 

a different device in place of the switch. 

4. 

If that device works, refer to the next step. 

5. 

If that device does not work, check the AC power
