114 System Diagnostics and Troubleshooting
Cause
Wake-on-LAN is not enabled.
Network controller is disabled.
Incorrect network driver.
No active network is detected.
Network controller is not set up
properly.
Network driver is not properly
loaded.
System cannot autosense the
network.
The cable is not securely connected. Be sure that both ends of the data cable are securely
The cable is attached to the
incorrect connector.
There is a problem with the cable or
a device at the other end of the
cable.
Network controller interrupt is
shared with an expansion board.
The network controller is defective.
Network drivers are not loaded, or
driver parameters do not match
current configuration.
The network controller is not
configured for this workstation.
Network controller interrupt is
shared with an expansion board.
The network controller requires
drivers.
The expansion board installed is a
network card (NIC) and conflicts
with the embedded NIC.
The files containing the network
drivers are corrupted.
The cable is not securely connected. Be sure that both ends of the cable are securely attached
The network controller is defective.
New network card might be
defective or might not meet industry-
standard specifications.
The network controller is not
configured properly.
Solution
Use the Network control application to enable Wake-on-
LAN.
Run Computer Setup and enable network controller.
Check the network controller documentation for the
correct driver or obtain the latest driver from the
manufacturer's Web site.
Check cabling and network equipment for proper
connection.
Use the Network control application to verify that the
device is working properly.
Reinstall network drivers.
Disable auto-sensing capabilities and force the system
into the correct operating mode.
connected.
Be sure that the cable is attached to the correct connector.
Be sure that the cable and device at the other end are
operating correctly.
Under the Computer Setup Advanced menu, change the
resource settings for the board.
Replace the NIC.
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.
Select the Network icon in the Control Panel and
configure the network controller.
Under the Computer Setup Advanced menu, change the
resource settings for the board.
Verify that the drivers were not accidentally deleted when
the drivers for a new expansion board were installed.
Under the Computer Setup Advanced menu, change the
resource settings for the board.
Reinstall the network drivers, using the Restore Plus! CD.
to the correct devices.
Replace the NIC.
Install a working, industry-standard NIC, or change the
boot sequence to boot from another source.
Verify Network Connectivity, that a DHCP Server is
present, and that the Remote System Installation Server
contains the NIC drivers for your NIC.
