When you are finished with this chapter, return to the “Overview of Mandatory Tasks for Installing Cisco Unity” chapter to continue installing the Cisco Unity system.

Note The tasks in the list reference detailed instructions in the Cisco Unity installation guide and in other Cisco Unity documentation. Follow the documentation for a successful installation.

Configuring a Dual NIC in the Cisco Unity Server

Note If the Cisco Unity server does not contain a dual NIC, skip this section.

We recommend that a dual NIC be configured in adapter fault tolerant mode (AFT) or network fault tolerant (NFT) mode. One NIC is designated as the primary and the other NIC as the secondary for active-passive fault tolerance. In this configuration, the primary (active) NIC handles 100 percent of the traffic. Only in the event that the primary NIC becomes unavailable does the secondary NIC then become active and handle 100 percent of the traffic.

Alternatively, if you do not want to configure AFT or NFT, or do not have a second LAN port available, the following configurations are supported, though not recommended:

•Disable TCP/IP for the second NIC, which allows you to re-enable the second NIC remotely if the first NIC fails. (Use the Network and Dial-up Connections Control Panel to disable TCP/IP for the second NIC.)

•Disable the second NIC in the BIOS. (On some Cisco Unity servers, the second NIC is disabled in the BIOS by default.)

Caution Note that not plugging a network cable into the second NIC is not sufficient. You must either disable TCP/IP for the second NIC or disable the second NIC in the BIOS, or Cisco Unity may not work properly.

If you installed Windows 2000 Server by using the Cisco Unity Platform Configuration discs, skip to the “Configuring a Dual NIC” section on page 5-4. (The NIC-configuration utility was installed automatically.)

If you installed Windows Server 2003 or if you installed Windows 2000 Server by using a retail Windows disc, you need to install the NIC-configuration utility before you can configure the dual NIC. Do the applicable procedures in the following two sections.

Installing the NIC-Configuration Utility

Note If you installed Windows 2000 Server by using the Cisco Unity Platform Configuration discs, skip this section.
