3. Troubleshooting
1. The Power LED is not lit
Check if the AC power cord is well connected. Try to unplug and plug back in the power
cord to the LAN Switch or try another power outlet.
2. The Link LED is not lit
Make sure the network configuration of connecting device is correct, and network card and
drivers are installed correctly.
Check the cable connections.
Make sure the cable distance between the Switch and other IEEE802.3 compatible
network device does not exceed 100 meters.
3. Performance is bad
Check the status of Ethernet switching. If Ethernet switching is set to full-duplex on one
device but a partner is set to half-duplex, then performance will be poor.
Make sure the cable between the switch and other IEEE802.3 compatible network device is
Category 5 UTP or better.
4.
Some devices can’t talk to other devices on the network
Check status of the Link LEDs to make sure devices are linked.
Make sure that the devices' network configurations are correct.
Reset the switch if needed.
