Diagnosing Switch Indicators

1.Symptom

Power LED does not light after power on.

Probable Causes

• AC power cord may be defective.

Possible Solutions

Check for loose connections.

Check the power outlet by using it for another device.

Replace the AC power cord.

2.Symptom

Link LED does not light after connection is made.

Probable Causes

Switch port, network card or cable may be defective.

Possible Solutions

Check that the switch and attached device are both powered on.

Be sure the network cable is connected to both devices.

Verify that Category 5 or better cable is used for 10/100 Mbps connections, Category 5 or 5e cable for 1000 Mbps connections, and that the length of any cable does not exceed 100 meters (328 feet).

Check the network card and cable connections for defects.

Replace the defective card or cable if necessary.
