This section provides troubleshooting information for problems that might occur with
the 10/100 Mbps Ethernet controller:
If the Ethernet controller cannot connect to the network, check the following:
•
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 persists, try a different cable.
If you set the Ethernet controller to operate at 100 Mbps, you must use Category 5
cabling.
If you directly connect two workstations (without a hub), or if you are not using a
hub with X ports, use a crossover cable.
Note: To determine whether a hub has an X port, check the port label. If the label
contains an X, the hub has an X port.
•
Determine if the hub supports auto-negotiation. If not, try configuring the
integrated Ethernet controller manually to match the speed and duplex mode of
the hub.
•
Make sure that you are using the correct device drivers, supplied with the
server/workstation.
•
Check for operating system-specific causes for the problem.
•
Make sure that the device drivers on the client and server/workstation are using
the same protocol.
•
Test the Ethernet controller:
How you test the Ethernet controller depends on which operating system you are
using (see the Ethernet controller device driver README file).

Ethernet controller problems that have definite symptoms.
