4.2 Maintenance and Service
●
If the device requires servicing of any kind, the user is required to disconnect and remove it from
its mounting. The initial installation should be done in a way that makes this as convenient as
possible.
●
Voltage / Power lines should be properly insulated as well as other cables. Be careful when
handling them so as to not trip over.
●
Do not under any circumstance insert foreign objects of any kind into the heat dissipation
holes located in the different faces of the device. This may not only harm the internal layout,
but might cause harm to users as well.
●
Do not under any circumstance open the device for any reason. Please contact your dealer
for any repair needed or follow the instructions within the manual.

Clean the device with dry soft cloth.
4.3 Troubleshooting
●
Always verify the right power cord or adapter is being used. Never use a power supply or adapter
with a non-compliant DC output voltage or it will burn the equipment.
●
Select the proper UTP or STP cable in order to construct the network. Use an unshielded
twisted-pair (UTP) or shield twisted-pair (STP) cable for RJ45 connections: 100Ω Category 5e for
10/100Mbps. Also be sure that the length of any twisted-pair connection does not exceed 100
meters (328 feet).
●
Diagnosing LED Indicators: To assist in identifying problems, the switch can be easily monitored
with the LED indicators which help to identify if any problems exist.
○
Please refer to the LED Indicators section for LED light indication.
●
If the power indicator LED does not turn on when the power cord is plugged in, the user may have
a problem with the power cord. Check for loose power connections, power losses or surges at the
power outlet.
