Troubleshooting

Diagnosing Switch Indicators

The switch can be easily monitored through panel indicators to assist the network
manager in identifying problems. This section describes common problems you may
encounter and possible solutions.
Symptom:Link indicator does not light up after making a connection.
Cause:Network interface (e.g., a network adapter card on the attached device), network
cable, or switch port may be defective.
Solution: Verify that the switch and attached device are powered on. Be sure the cable is
plugged into both the switch and corresponding device. 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.
Symptom:Power indicator does not light up after power on.
Cause:Defective power outlet, power cord, or internal power supply.
Solution:Check the power outlet by plugging in another device that is functioning
properly. Check the power cord with another device. If these measures fail to resolve the
problem, contact Alcatel Technical Support.

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 as explained in the
previous section. 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 side of the unit are unobstructed and running prior to shutdown. If you still cannot
isolate the problem, then the internal power supply may be defective. In this case, contact
your Alcatel distributor for assistance.

Installation

Verify that all system components have been properly installed. If one or more
components appear to be malfunctioning (e.g., the power cord or network cabling), test
them in an alternate environment where you are sure that all the other components are
functioning properly.
