Troubleshooting

Use Table 3-1 to identify problems with the modules and take the appropriate
corrective action.

Table 3-1

Common Problems and Their Solutions

Symptom

Possible Causes

Corrective Action

Port LED is
amber.

Thumbscrews have not been
tightened.

Tighten thumbscrews.

Spanning Tree Protocol is
checking for loops.

Wait for Spanning Tree Protocol to complete
its search. The LED turns green when
Spanning Tree Protocol completes its check.

Port is initializing, it was disabled
by management or an address
violation, or it was blocked by
Spanning Tree Protocol.

Use Visual Switch Manager or the IOS
command-line interface to check the status of
the port and to enable it.

Port LED is
alternating
between green and
amber.

Port is experiencing error frames.
This could be due to a duplex
mismatch caused by
autonegotiation, collisions, CRC
errors, or alignment errors.

Check the duplex settings on both devices.
Check the speed settings on both devices
except when using a gigabit Ethernet module.
You cannot change the speed on the gigabit
Ethernet modules. If one parameter is
manually set, manually set all of them, or set
both devices to autonegotiate speed and
duplex. See the
