6. TROUBLESHOOTING

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

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

Solution:

The address table may contain older information than of the address table of that node. Please power down to refresh the address information, please also check VLAN configuration.

Performance is bad

Solution:

Check the full duplex status of the Managed Switch. If the Managed 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 lit, but traffic is irregular

Solution:

Check that the attached device is not set to dedicated 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.
