Troubleshooting

This chapter contains information to help you solve common problems. If the Ethernet Switch is not functioning properly, make sure the Ethernet Switch was set up according to the instructions in this manual.

The Link LED is not lit

Solution:

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

Some stations cannot talk to other stations located on the other port Solution:

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

Performance is poor

Solution:

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?

Solution:

1.Check the LNK/ACT LED on the switch

2.Try another port on the Switch

3.Make sure the cable is installed properly
