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.)
