Trouble Shooting
The Switch can be easily monitored through panel indicators to
assist in identifying problems. This section describes common
problems you may encounter and where you can find possible
solutions.
??
Diagnosing LED Indicators
IF Link indicator does not light up after making a connection.
You may check whether network interface (e.g., a network
adapter card on the attached device), network cable, or switch
port is defective or not. Be sure the cable is plugged into both
the Switch and corresponding device. Verified the proper
cable type is used and its length does not exceed specified
limits.
??
Power
IF the power indicator does not turn on when the power cord is
plugged in, you may have a problem with power outlet, or
power cord. However, if the switch powers off after running for
a while, check for loose power connection, power loses or
surges at power outlet. If you still cannot resolve the problem,
contact your local dealer for assistance.
