Troubleshooting the Ethernet Controller
This section provides troubleshooting information for problems that might occur
with the 10/100/1000-Mbps Ethernet controller.

Network Connection Problems

If the Ethernet controller cannot connect to the network, check the following
conditions:
•Make sure that the cable is installed correctly.
The network cable must be securely attached at all connections. If the cable
is attached but the problem remains, try a different cable.
If you set the Ethernet controller to operate at either 100 Mbps or 1000 Mbps,
you must use Category 5 or higher cabling.
•Determine whether the hub supports autonegotiation. If it does not, try
configuring the integrated Ethernet controller manually to match the speed
and duplex mode of the hub.
•Check the Ethernet controller LEDs on the device back panel. (See
Figure 1-3.)
