Troubleshooting

19.1 Using LEDs to Diagnose Problems

The LEDs are useful aides for finding possible problem causes.

19.1.1 Power LED

The

PWR

LED on the front panel does not light up.

Table 19-1 Troubleshooting Power LED

STEPS CORRECTIVE

ACTION

1

Check the connections from your switch to the power source. Make sure you are
using the supplied power cord and proper power supply. Refer to the product
specifications.

2

Make sure the power source is turned on and that the switch is receiving sufficient
power.

3

If these steps fail to correct the problem, contact your local distributor for
assistance.

19.1.2 The LK/ACT LED

The

LK/ACT

LED does not light up when a device is connected.

Table 19-2 Troubleshooting LK/ACT LED

STEPS CORRECTIVE

ACTION

1

Verify that the attached device(s) is turned on and properly connected to the
switch.

2

Make sure the network adapters are working on the attached devices.

3

Verify that 10/100/1000 M Ethernet cable length does not exceed 100 meters. For
more information on network cables, see the section on network cable types.

19.1.3 The 100 LED

The

100

LED does not show the speed of my Ethernet device.
