4. Trouble Shooting

The Palm Switch 500 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.

•Cabling
