Chapter 3 Troubleshooting
Power Problems
If the power LED is not lit when power is connected, this could be a problem with the power outlet,
power cord, or internal power supply. Check that the power cord is firmly connected to a known-
good supply of power. If the power LED still doesn't come on, there may be a problem with the
internal power supply unit.
Access from the Network
You can use a Web browser to access and manage the switch from anywhere on the network to
which it is connected. However, you must configure a valid IP address, subnet mask, and default
gateway settings on the switch in advance. Check the following points if you are unable to establish
a link with the switch.
• The network connection is valid.
• The switch has a valid IP address.
• The connected port is not disabled.
• There are no problems with the connected Ethernet cable.
