4. From the Windows NT Server desktop, select Control Panel, then select the
Network icon, then select the Adapters tab.
5. Highlight one of the adapters that will be in the redundant pair and then click the
Properties... button.
6. Check the Grouping box. This will show the possible combinations for redundant
pairs.
7. Select the adapter pair you want and then select OK. Note that the integrated
Ethernet controller is located at PCI C.
Two options are available for recovering from a failover condition. The options
are determined by the Enable for DMI / Hot Swap Support checkbox. If the IBM
Hot Plug PCI for Windows NT Server 4.0 package is installed, this checkbox will
appear at the bottom of the Adapter Properties panel. If you do not have the IBM
Hot Plug PCI for Windows NT Server 4.0 package installed on the server, you will
not see the Enable for DMI / Hot Swap Support checkbox.
If the Enable for DMI / Hot Swap Support checkbox is not checked or is not
present, traffic will automatically switch back to the primary adapter when the
primary link status is restored. In this mode, the adapter cannot be hot-swapped.
Users with the IBM Hot Plug PCI for Windows NT Server 4.0 package installed
should check the Enable for DMI / Hot Swap Support checkbox.
If the Enable for DMI / Hot Swap Support checkbox is checked, traffic will
remain on the secondary adapter until the user directs it to return to the primary
adapter. This can be done after the hot-swap replacement of the primary adapter
or by using the DMI interface.
8. Select Close to exit from the Network setup.
When you restart the server, the failover function will be in effect.
If a failover occurs, a message is written to the NT Event Viewer log. In addition, if
the Enable for DMI / Hot Swap Support checkbox is checked, a DMI alert will also be
generated.

The failover function is now enabled. If a failover occurs:
The operating system console generates a message.
The custom counters for the device driver contain variables that define the state of
the failover function and the location of the redundant pair. You can use the
NetWare Monitor to view the custom counters.
Note: If the primary adapter was hot-replaced while the Ethernet traffic was being
handled by the secondary Ethernet controller, the traffic does not
automatically switch back to the primary adapter when the primary adapter
comes back online. In this case, issue the command:
LOAD d:\path\PCNTNW SCAN
where d and path are the drive and path where the driver is located. This
command causes the device driver to locate the primary adapter and switch
the Ethernet traffic to it.
Ethernet port connector
The following table shows the pin-number assignments for the RJ-45 connector.
These assignments apply to both 10BASE-T and 100BASE-TX devices.
