Troubleshooting Chart<br />

Power LED is Off • Check connections between the switch, the power<br />

cord, and the wall outlet.<br />

• Contact your dealer for assistance.<br />

• Contact <strong>SMC</strong> Technical Support.<br />

Link LED is Off • Verify that the switch and attached device are powered<br />

on.<br />

• Be sure the cable is plugged into both the switch and<br />

corresponding device.<br />

• Verify that the proper cable type is used and its length<br />

does not exceed specified limits.<br />

• Check the adapter on the attached device and cable<br />

connections for possible defects. Replace the defective<br />

adapter or cable if necessary.<br />

If the power indicator does not turn on when the power cord is plugged in,<br />

you may have a problem with the power outlet, power cord, or internal<br />

power supply. However, if the unit powers off after running for a while,<br />

check for loose power connections, power losses or surges at the power<br />

outlet, and verify that the fans on the unit are unobstructed and running<br />

prior to shutdown. If you still cannot isolate the problem, then the internal<br />

power supply may be defective.<br />
