One or more workstations cannot communicate with a server or other device through the
switch
• Explanation: This symptom might be noticed on one or more segments connected
to the switch, and could be caused by cable faults, inappropriate configuration or
faulty installation.
• Action: Check all connections and verify your configuration. Check any error
counters for the ports.
The 100Mbps ports are not working, or work very poorly
• Explanation: This is probably due to incorrect configuration of the auto-negotia-
tion duplex settings and link speeds.
• Action: Check the negotiated settings in the switch and compare them to the
expected values.
I have poor performance and high numbers of second port drops
• Explanation: There may be a loop in the network and Spanning Tree is not
enabled.
• Action: Avoid loops, or alternatively, either enable STP on all the ports (using
Device Setup) or specific ports (using Port Setup).
