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.
