Problem Cause Solution
Diagnostics reports a failure. The cable is not securely
connected.
Be sure that both ends of the data cable are securely
connected.
The cable is attached to the
incorrect connector.
Be sure that the cable is attached to the correct connector.
There is a problem with the cable
or a device at the other end of the
cable.
Be sure that the cable and device at the other end are
operating correctly.
Network controller interrupt is
shared with an expansion board.
Under the Computer Setup Advanced menu, change the
resource settings for the board.
The network controller
is defective.
CAUTION Disconnect AC power from the
workstation before reseating or replacing
components because there is power to the
system board even when the workstation is
powered down.
Replace the NIC.
Diagnostics passes, but the
workstation does not
communicate with the network.
Network drivers are not loaded, or
driver parameters do not match
current configuration.
1. Be sure the network drivers are loaded and that the
driver parameters match the configuration of the
network controller.
2. Be sure the correct network client and protocol is
installed.

The network controller requires
drivers.
Verify that the drivers were not accidentally deleted when
the drivers for a new expansion board were installed.
The expansion board installed is a
Network Interface Card (NIC) and
conflicts with the embedded NIC.
Under the Computer Setup Advanced menu, change the
resource settings for the board.
Network controller stops working
without apparent cause.
The files containing the network
drivers are corrupted.
Reinstall the network drivers, using the Restore Plus! CD.
The cable is not securely
connected.
Be sure that both ends of the cable are securely attached
to the correct devices.
The network controller is
defective.
CAUTION Disconnect AC power from the
workstation before reseating or replacing
components because there is power to the
system board even when the workstation is
powered down.
Replace the NIC.
New network card will not boot. New network card might be
defective or might not meet
industry-standard specifications.
Install a working, industry-standard NIC, or change the
boot sequence to boot from another source.
