Troubleshooting the Ethernet controller

This section provides troubleshooting information for prob-
lems that might occur with the 10/100 Mbps Ethernet con-
troller.

Network connection problems

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 cross-
over 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 manu-
ally to match the speed and duplex mode of the hub.
• Check the Ethernet controller lights on the operator
information panel.
These lights indicate whether a problem exists with the
connector, cable, or hub.
— The Ethernet Link Status light illuminates when
the Ethernet controller receives a LINK pulse from
the hub. If the light is off, there might be a defec-
tive connector or cable, or a problem with the hub.
— The Ethernet Transmit/Receive Activity light illumi-
nates when the Ethernet controller sends or
receives data over the Ethernet Network. If the
Ethernet Transmit/Receive Activity light is off,
make sure that the hub and network are operating
and that the correct device drivers are loaded.
— The Ethernet Speed 100 Mbps light illuminates
when the Ethernet controller LAN speed is
100 Mbps.
• Make sure that you are using the correct device drivers,
supplied with the server.
• Check for operating system-specific causes for the
problem.
• Make sure that the device drivers on the client and
server 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 con-
troller device driver README file).
