Select
Hardware 
Add new LAN adapter.
Further configuration will be determined by the bus type of your
machine and the ability of the Network Configuration Manager to
detect your adapter. See:
- ``Configuring PCI, PC Card, EISA, and MCA adapters''
- ``Configuring ISA adapters''
- ``Searching for adapters''
NOTE: Configuring a complete network interface includes configuring a protocol with your adapter; see ``Configuring protocols''.
If you want to configure an adapter as a backup device,
select
Hardware Add new LAN adapter.
On the Add Protocol screen select
Backup Device instead of a protocol suite
such as TCP/IP or IPX/SPX.
Then select an existing network adapter (the primary device)
for which the new adapter will act as a backup device and click
on OK.
See
``Configuring a backup device''
for more information.
If the primary device fails, the system will automatically switch to using the backup device. The Network Configuration Manager indicates that a primary device has failed or is otherwise unavailable for use by placing a cross on the icon for the network adapter. (In character mode, the string ``HX'' replaces ``HW''.)
If you want to force the system to use the backup device instead of the
primary device, select the primary device from the list, and then select
Hardware Switch to Backup.
Once you have replaced a failed primary device, you can switch the
system back to using this device instead of the backup device.
To do this, select the backup device from the list, and then select
Hardware Revert to Primary.
NOTE: If you had to shut down the system to replace the failed primary device, the system will automatically revert to using the primary device on being rebooted.
When replacing a failed primary device, you must normally use the same type of network adapter. Note, however, that some vendor-specific hardware may support the interchange of different types of devices provided that they are supported by the same device driver. Please refer to the documentation provided by the vendor for more information.
Select the adapter to modify from the list, and then select
Hardware Modify hardware configuration.
Enter new configuration parameters
as you did when adding adapters.
Select the adapter to test from the list, and then select
Hardware Test Network Connectivity.
This sends a broadcast message to the broadcast MAC
(Media Access Control) address using LLC (Logical Link
Control) TEST
frames.
The response will display one of these messages:
success- indicating that the hardware connections are valid, and the send and receive paths are verified
noanswerorbind failed-
which might indicate one of these problems:
- a defective network adapter
- physical connection problems; see ``Checking physical network connections''
- incorrect configuration parameter settings (this is most likely with ISA and PC Card adapters; see ``Driver configuration'')
- you need to reboot your system (this is only required by a few older drivers; see ``Driver configuration'')
NOTE: If your machine is the only one on the network, you might receive an erroneous
noanswer.
This procedure only tests the adapter's ability to reach the network; it does not detect protocol problems. See ``Troubleshooting network configuration'' for more troubleshooting information.
Select the adapter to view from the list,
then select
Hardware View hardware configuration.
Select the adapter to deconfigure from the list, and then select
Hardware Remove network device.
You will be prompted to
confirm your choice and informed when the operation is complete.
NOTE: If your network interface includes only one adapter, deconfiguring the adapter will also deconfigure any protocols above it.
To reconfigure a backup device as a primary device, first deconfigure the network adapter and then configure the device as a new LAN adapter.
