Appendix A: Troubleshooting

Diagnosing Switch Indicators

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 verify that the fans on
the unit are unobstructed and running prior to shutdown. If you still cannot isolate the
problem, then the internal power supply may be defective.

Table A-1 Troubleshooting Chart

Symptom

Action

Power LED is Off

• Check connections between the switch, the power cord, and the wall

outlet.

• Contact your dealer for assistance.
• Contact our Technical Support.

Link LED is Off

• Verify that the switch and attached device are powered on.
• Be sure the cable is plugged into both the switch and corresponding

device.

• If the switch is installed in a rack, check the connections to the

punch-down block and patch panel.

• 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.
