Table 5-13 Network problems
Problem
Wake-on-LAN feature is not
functioning.
Network driver does not detect
network controller.
Network status link light does not

board was added to the
workstation.
ENWW
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 auto-sense the
network.
The cable is not securely
connected.
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.
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 website.
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.
Be sure that both ends of the data cable are securely
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.
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.
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.
