Chapter 1 Installing Cisco Unity Connection
Important Considerations for Installation
Important Considerations for Installation
Before you proceed with the installation, consider the following points:
• Verify the system requirements, such as licensing and phone integration requirements necessary for
the Unity Connection server in the System Requirements for Cisco Unity Connection guide at
http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/connection/10x/requirements/10xcucsysreq
s.html.
• Be aware that when you install on an existing Unity Connection server, the hard drive gets formatted
and all existing data on the drive gets overwritten.
• Ensure that you connect each Unity Connection server to an uninterruptible power supply (UPS) to
provide power backup and protect your system. Failure to do so may result in damage to physical
media and require a new installation.
• For a Unity Connection cluster:
–
Install the Unity Connection software first on the publisher server and then on the subscriber
server (applicable to only standard installation scenarios). For more information on installation
scenarios, see Installation Scenarios.
–
Note down the Security password that you mention at the time of installing publisher server.
You need to specify the same password when installing the subscriber server in a cluster.
–
Do not run Network Address Translation (NAT) or Port Address Translation (PAT) between the
publisher and subscriber servers.
• Verify that DNS server is properly configured before installing Unity Connection. For more
information, see the “Verifying DNS Settings” section on page 1-5.
• Do not perform any configuration changes during the installation.
• Be aware that the directory names and filenames that you enter during the installation are
case-sensitive.
Pre-Installation Tasks
Before installing a Unity Connection server, you need to understand all the pre-installation steps as well.
The Table 1-1 contains a list of pre-installation tasks that you must consider to ensure successful
installation of Unity Connection server.

Step 1
Ensure that your servers are listed as supported hardware and
sized appropriately to support the load of the cluster.

Create the virtual machine using the correct OVA template. For more information, see the Creating a Virtual
Machine, page 1-3 section.
Step 3
Change the boot order of the virtual machine to update the
BIOS settings.
