Before you begin

This chapter discusses how you should prepare for the installation of the IM and Presence Service.

Read this first

When you install the IM and Presence Service on an existing server, the hard drive is formatted, and all existing data on the drive is overwritten.

DNS requirements

Note the following DNS requirements:

  • Mixed-mode DNS deployments not supported—Cisco does not support mixed-mode deployments. Both Cisco Unified Communications Manager (Unified CM) and IM and Presence must either use or not use DNS.
  • Unified CM and IM and Presence should use the same DNS server—If you use different DNS servers between IM and Presence and Unified CM, it is likely to cause abnormal system behavior.
  • Multi-node considerations—If you are using the multi-node feature in IM and Presence, see the section regarding multi-node deployments in the Deployment Guide for IM and Presence for DNS configuration options.

Installation time requirements

The entire IM and Presence installation process, excluding pre- and post-installation tasks, takes approximately 45 to 120 minutes per server, depending on your server type.

System requirements

Required passwords

During installation of the IM and Presence Service, you must specify the following usernames and passwords:

  • Administrator account username and password
  • Application username and password
  • Security password
Related References

Administrator account username and password

During installation, you must create an Administrator Account username and password to log into the following areas:

  • Cisco Unified Operating System Administration interface
  • Disaster Recovery System Administration interface
  • Command Line Interface (CLI)

The Administrator login must start with an alphabetic character, be at least six characters long, and can contain alphanumeric characters, hyphens, and underscores.

If you lose the Administrator password and cannot access the system, you can recover the Administrator password in Cisco Unified Communications Operating System Administration.

If you need to reset the Administrator password, use the CLI.

Related References

Application username and password

During installation, you must create an Application User user ID and password to sign into the Cisco Unified CM IM and Presence Administration interface.

If you need to reset the Application User password, use the CLI.

Related References

Security password

During installation, you must specify a system security password. This password is used to secure communication between cluster nodes. In the Post-Installation deployment wizard, which displays the first time you sign in to Cisco Unified CM IM and Presence Administration, you must reset the security password to be identical to the password used on the Cisco Unified Communications Manager (Unified CM) publisher server.


Note

The security password that you set for IM and Presence in the Post-Installation deployment wizard must be identical to the password used on the Unified CM Publisher server. The system uses this password to authorize communications between nodes, and you must ensure that this password is identical on all nodes in the cluster.

If you lose the Unified CM security password, there is no way to verify from IM and Presence what the security password is on the Unified CM server. See Cisco Unified Communications Manager documentation for information about how to retrieve the security password.

To reset the Unified CM security password after your first sign in to Cisco Unified CM IM and Presence Administration, (for example, if the password has changed on Unified CM and you need to update it on IM and Presence) select System > CUCM Publisher from Cisco Unified CM IM and Presence Administration.

Required installation information

When you install the IM and Presence Service on a server, the installation process requires certain information that you must provide. You can provide this information manually during the installation process or you can provide it using an answer file. For each IM and Presence server that you install in a cluster, you must gather this information before you begin the installation process.

The following table lists the information that you must gather before you install IM and Presence.


Note

Because some of the fields are optional, they may not apply to your configuration. For example, if you decide not to set up an SMTP host during installation, the parameter still displays, but you do not need to enter a value.

The last column in the table shows whether you can change a parameter after installation, and if you can, if provides the appropriate menu path or Command Line Interface (CLI) command.

  • Cisco Unified Communications Manager server For Cisco Unified Communications Manager hardware support, see the Cisco Unified Communications Manager compatibility matrix.

If you are configuring the IM and Presence multi-node feature in your network, review the multi-node hardware recommendations in the Deployment Guide for IM and Presence Service on Cisco Unified Communications Manager, Release 9.0(1) .


Note

You must ensure that all MCS platforms contain a minimum of 4 GB of RAM.

Software restrictions

IM and Presence can only upload and process software that Cisco Systems approves. You cannot install or use third-party Linux or Windows-based software applications with IM and Presence. You perform valid software installations and upgrades in Cisco Unified Communications Operating System Administration.

For information about software compatibility, see the Hardware and Software Compatibility Information for IM and Presence Service on Cisco Unified Communications Manager, Release 9.0(1) .

Perform pre-installation tasks

You must complete the following pre-installation tasks before you begin to install the IM and Presence software.

Procedure
    Step 1   Ensure that the Cisco Unified Communications Manager (Unified CM) and IM and Presence software versions match.
    Step 2   Gather all the information you need to complete the installation and configuration of the IM and Presence software.
    Step 3   If you are installing a subscriber node, ensure that you add the subscriber node to the IM and Presence publisher node Cluster Topology.
    Step 4   Ensure that the IM and Presence server has network access to the Unified CM publisher server.

    You can ping Unified CM from other servers.

    Step 5   Ensure that you turn on the Cisco AXL Web Service on the associated Unified CM server.

    Select Tools > Service Activationin Cisco Unified Serviceability.

    Step 6   If you use DNS, ensure that you have configured the host name of the new IM and Presence server on the DNS server and that the DNS server can resolve the host name of the Unified CM publisher server and of other IM and Presence servers (if any).
    Caution   

    Cisco recommends that you use the same DNS servers between IM and Presence and Unified CM. If you use different DNS servers, it is likely to cause abnormal system behavior. Both Unified CM and IM and Presence must either use or not use DNS because Cisco does not support mixed-mode deployments. If you are using the multi-node feature in IM and Presence, see the Deployment Guide for IM and Presence Service on Cisco Unified Communications Manager for DNS configuration options.

    Cluster topology

    The system automatically assigns the first IM and Presence node that you install as the publisher node. For a multi-node IM and Presence deployment, after you install the publisher node you must create the required subclusters and subscriber nodes in your IM and Presence cluster. You perform the system topology configuration on the IM and Presence publisher node; select System > Cluster Topology in Cisco Unified CM IM and Presence Administration.

    You must create the subscriber nodes in your topology (on the publisher node) before you install the IM and Presence software on these nodes. However, you cannot assign these subscriber nodes to a subcluster until after you install IM and Presence software on these subscriber nodes. If you assign a subscriber node to a subcluster before you install it, users in remote clusters will not receive availability information. An availability outage will occur until the node is installed.

    Deploy multiple nodes in cluster

    A typical process for deploying multiple nodes in a cluster is as follows:

    For more information about configuring the cluster topology, see the Deployment Guide for IM and Presence Service on Cisco Unified Communications Manager .

    Procedure
      Step 1   Install the publisher node.
      Step 2   In Cluster Topology, on the publisher node, create all the subclusters and subscriber nodes.
      Step 3   Install each of the subscriber nodes in the cluster.
      Step 4   In Cluster Topology, on the publisher node, assign the subscriber nodes to the subcluster arrangement as required.

      Unattended installation of IM and Presence

      IM and Presence can be installed unattended using an XML answer file that reads predefined configuration values during the installation process.

      Cisco Unified Communications Answer File Generator, a web application, generates answer files for unattended installations of IM and Presence. You must generate the answer file, copy it to a USB key and use it with the IM and Presence DVD during the installation process.

      The generated XML answer file may be quite large, for example, 1 Gigabyte. Therefore, you may need to reformat the USB key to support a large storage capacity before you save the XML file to the USB key.


      Note

      You can only use answer files for fresh installations of IM and Presence and not for upgrades.

      To generate an answer file for unattended installation and configuration of IM and Presence you must access the Cisco Unified Communications Answer File Generator at the following URL:

      http://www.cisco.com/web/cuc_afg/index.html

      The web application supports the following features:

      • Generates and saves answer files for unattended installations on the publisher server and all subsequent servers.
      • Provides syntactical validation of data entries.
      • Supports Internet Explorer version 6.0 or higher and Mozilla version 1.5 or higher.
      • Provides online help and documentation.
