SMC Networks 10/100 Mbps Manual De Usuario

38

There may be a network connection problem if the LED on the card’s 
bracket does not light, or if you cannot access any network resources from 
the computer. Check the following items before contacting SMC Technical 
Support.

•

Be sure you are using Category 5 cable for 100 Mbps connections, and 
that the length of any cable does not exceed 100 m (328 ft).

•

Inspect all network cables and connections. Make sure the network 
cable is securely attached to the card’s connector.

•

Make sure the correct network card driver is installed for your 
operating system. If necessary, try reinstalling the driver.

•

Make sure the computer and other network devices are receiving 
power. If you suspect a power outlet to be faulty, plug another device 
into it to verify that it is working.

•

If the network card’s speed or duplex mode has been configured 
manually, check that it matches that of the attached network device 
port. Note that it is recommended to set the card to auto-negotiation 
when installing the network driver.

•

The port on the network device that the card is attached to may be 
defective. Try using another port on the device.

•

If you cannot access a Windows or NetWare service on the network, 
check that you have enabled and configured the service correctly. If 
you cannot connect to a particular server, ensure that you have access 
rights and a valid ID and password.

•

If you cannot access the Internet, be sure you have configured your 
system for TCP/IP.
