Troubleshooting

15-1

This chapter covers potential problems and possible remedies. After each problem description, some

instructions are provided to help you to diagnose and to solve the problem.

15.1 Using LEDs to Diagnose Problems

The LEDs are useful aides for finding possible problem causes.

15.1.1

The Power LED

The

PWR

LED on the front panel does not light up.

Table 15-1 Troubleshooting Power LED

STEPS CORRECTIVE

ACTION

1

Check the connections from the VSG 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 VSG is receiving sufficient power.

3

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

15.1.2

The LAN LEDs

None of the LEDs for the LAN port light up when connected to an Ethernet device.

Table 15-2 Troubleshooting LAN LEDs

STEPS CORRECTIVE

ACTION

1

Make sure you are using the correct Ethernet cable. Connect the LAN port to a hub/switch using a
crossover Ethernet cable or directly to a computer using a straight-through Ethernet cable.

2

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

3

Verify that Ethernet cable length does not exceed 100 meters.

4

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

15.1.3

The WAN LEDs

None of the LEDs for the WAN port light up when connected to an Ethernet device.

Table 15-3 Troubleshooting WAN LEDs

STEPS CORRECTIVE

ACTION

1

Make sure you are using the correct Ethernet cable. Connect the WAN port to a router using a straight-
through Ethernet cable or directly to a computer using a crossover Ethernet cable.

2

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

3

Verify that Ethernet cable length does not exceed 100 meters.

4

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