5. Troubleshooting
5.1 Resolving No Link Conditions
The possible causes for a no link LED status are as follow:
l The attached device is not powered on
l The cable may not be the correct type or is faulty
l The installed building premise cable is faulty
l The switch port may be faulty
Note: Because Port 16 MDI-X port and the MDI port share the same
components, if the Port 16 MDI-X port is used, please don't use the MDI port.
Or, if the MDI port is used, please don't use the Port 16 MDI-X port.
5.2 Q&A
1. Computer A can connect to Computer B, but cannot connect to Computer C
through the 16-port Switch.
¸ The network device of Computer C may fail to work. Please check the
link/act status of Computer C on the LED indicator. Try another network
device on this connection.
¸ The network configuration of Computer C may be something wrong.
Please verify the network configuration on Computer C.
2. The possible causes for the 16-port Switch no work status are as follow:
¸ Power cord or the internal power supply problem. Check the Power LED
indicator.
¸ MDI/MDI-X port is misused. Never use MDI port and Port 16 MDI-X port
at the same time because they share the same components.
¸ The cable may not be the correct type or is faulty. And the cable length
limit is 100 meters.
¸ The installed building premise cable is faulty.
3. The LED display does not work correct.
