Diagnosing switch indicators
Troubleshooting chart TABLE 24
Symptom Action
Power LED is Off • Internal power supply is disconnected.
• Check connections between the device, the power cord, and the wall outlet.
• Contact Technical Support.
Power LED is Amber Internal power supply has failed. Contact Technical Support.
Diag LED is Amber • The device self test has detected a fault.
• Power cycle the device to try and clear the condition. If the condition persists, contact
Technical Support.
Link LED is Off • Verify that the device and attached device are powered on.
• Be sure the cable is plugged into both the device and corresponding device.
• Verify that the proper cable type is used and its length does not exceed specified limits.
• Check the adapter on the attached device and cable connections for possible defects.
Replace the defective adapter or cable if necessary.
Installation
Verify that all system components have been properly installed. If one or more components appear to
be malfunctioning (such as the power cord or network cabling), test them in an alternate environment
where you are sure that all the other components are functioning properly.
Power and cooling problems
If the power indicator does not turn on when the power cord is plugged in, you may have a problem with
the power outlet, power cord, or internal power supply. However, if the unit powers off after running for a
while, check for loose power connections, power losses or surges at the power outlet, and use the
show chassis command to verify that the temperature is below the shutdown threshold. If you still
cannot isolate the problem, then the internal power supply may be defective. In this case, contact
Technical Support for assistance.
