Troubleshooting

The LEDs on the front panel can help you to define the network
failures. This section describes common problems you can possibly
face with and the ways to fix them.
1. Link LED
If the Link LED is off after connecting a device you should:
• check the network interfaces of the device you connect and
of the switch;
• check the network cable you use;
make sure the network cable connected into both network
•
interfaces (of the switch and the device you intend to
connect);
• make sure the length of the cable does not exceed the
specified limit (100 meters).
2. Power LED
If the Power LED is off after plugging the power cable into the
socket and the outlet please make sure that:
• there is power in the outlet;
• the power cable is not damaged
If after the plugging the power cable the Power LED lights up but
then turns off after a while, make sure that:
• there is no significant wears in your electric grid;
• the power cable is not tightened (it can cause inadvertent
unplugging).
If you still experience the problem please contact the service center.
