Setting Up Exchange


In this chapter, you do the following tasks in the order listed:


Note If you are installing the secondary Cisco Unity server now, skip Task 1.


1. Determine the Exchange server that Cisco Unity will connect with, known as the partner Exchange server. See the "Determining the Partner Exchange Server" section.

2. Install Exchange administration software on the Cisco Unity server. See the "Installing Exchange 5.5 Administration Software" section.

3. Install the latest Exchange service pack (if any) and updates that are recommended for use with Cisco Unity. See the "Installing the Latest Exchange Service Pack and Updates" section.

When you are finished with this chapter, return to "Overview of Mandatory Tasks for Installing Cisco Unity" 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.


Determining the Partner Exchange Server

During configuration of the Cisco Unity software, you will be prompted to select an Exchange server for Cisco Unity to connect with. The server is known as the partner Exchange server, or the partner server. You decide now which server you will use as the partner server, based on the following information; you specify the partner server later in the installation process.

When all Cisco Unity subscriber mailboxes will be homed on the same Exchange server, use that server as the partner server.

When Cisco Unity subscriber mailboxes will be homed on more than one Exchange server, consider the following general guidelines for deciding which server to use as the partner server:

All voice messages from outside callers pass through the partner server on their way to user mailboxes. Use an Exchange server based on its ability to handle the additional traffic.

When Exchange is configured for active/active or active/passive clustering, use either an Exchange server outside the cluster or the Exchange virtual server in the cluster.

Installing Exchange 5.5 Administration Software


Note Cisco assumes that the Exchange environment is already set up and working before the Cisco Unity system is installed.


When Exchange 5.5 is installed on the partner server, you install Exchange 5.5 administration software on the Cisco Unity server because it includes the Microsoft messaging API (MAPI). MAPI is the application programming interface that Cisco Unity uses to communicate with Exchange for addressing, sending, and retrieving messages.

This section contains three procedures. Do the procedures in the order listed, as applicable.

The first procedure, "To Change the LDAP Port Number of the Exchange 5.5 Server (When Active Directory Is Installed)," applies only if Active Directory is installed on the partner Exchange 5.5 server. Cisco Unity communicates with Exchange 5.5 by using Lightweight Directory Access Protocol (LDAP). Active Directory also uses LDAP, and it reserves port 389 for the protocol. The default LDAP port for Exchange 5.5 is also 389. The Active Directory LDAP port cannot be reconfigured, so the Exchange LDAP port number must be reset.

To Change the LDAP Port Number of the Exchange 5.5 Server (When Active Directory Is Installed)


Step 1 On the Windows Start menu, click Programs > Microsoft Exchange > Microsoft Exchange Administrator.

Step 2 In the site container, open the Configuration container.

Step 3 Under Configuration, click Protocols.

Step 4 In the right pane, double-click LDAP (Directory) Site Defaults.

Step 5 On the General tab, change Port Number to 2015 (or another available port number). Make note of the new port number, which you will need later in the installation process.

Step 6 Click OK, and close the Exchange Administrator.


To Install Exchange 5.5 Administration Software on the Cisco Unity Server


Step 1 On the Cisco Unity server, insert the Cisco Unity Message Store 5.5 disc in the CD-ROM drive.

If the disc does not run automatically, browse to the root directory, and double-click Launch.exe.

Step 2 When the Microsoft Exchange Server Version 5.5 window appears, click Setup Server and Components.

Step 3 Click Microsoft Exchange Server 5.5.

Step 4 Accept the license agreement.

Step 5 Click Complete/Custom.

Step 6 Uncheck all check boxes except the Microsoft Exchange Administrator check box.

Step 7 Click Continue.

Step 8 When you are prompted to enter a CD key, enter the key for Cisco Unity Message Store 5.5 from the sticker located on the CD sleeve.

Step 9 Click OK.

Step 10 Follow the on-screen prompts to complete the installation.


To Install Exchange 5.5 Service Pack 4


Step 1 On Cisco Unity Service Packs CD 2, browse to the directory Exchange5.5_SP4, and double-click Update.exe.

Step 2 Follow the on-screen prompts to complete the installation.

Step 3 Restart the server.

Step 4 If Exchange 5.5 Service Pack 4 is not already installed on the partner Exchange server, repeat Step 1 through Step 3 on that server.


Installing the Latest Exchange Service Pack and Updates

Install the latest Exchange service pack (if any) and updates that are recommended for use with Cisco Unity. These are the service pack and updates that you downloaded in the "Downloading Software for the Installation" section.

Some Exchange updates can be installed only after a prerequisite service pack has been installed. Install the service pack, if any, before you install updates.

To Install the Latest Exchange Service Pack


Follow the instructions that you printed or downloaded when you downloaded the service pack.


To Install the Latest Exchange Updates


Step 1 Insert the Cisco Unity Post-Install disc in the CD-ROM drive.

Step 2 Browse to each of the applicable directories and install the correct language version of each update: English (ENU), French (FRA), German (DEU), or Japanese (JPN). (For example, if the French version of Exchange 5.5 administration software is installed on the Cisco Unity server, install the French version of any Exchange 5.5 updates.)

To speed the installation, you may want to:

Install each update at a command prompt by using the /z option, so you do not have to restart the computer after installing each update.

Install each update at a command prompt by using the /m option, so the update installs without displaying any dialog boxes.

Create a batch file that installs all of the updates at once.

Step 3 Restart the Cisco Unity server.
