This chapter describes how to install the software for the Cisco TelePresence Exchange System.
•Determining the Method and Order of Installation
•Options for Connecting to the Cisco TelePresence Exchange System Servers for Installation
•Installing and Synchronizing the Cisco TelePresence Exchange System Database Servers
•Installing the Cisco TelePresence Exchange System Call Engine Servers
•Installing the Cisco TelePresence Exchange System Administration Servers
•Verifying Data Connectivity Among the Servers
Determining the Method and Order of Installation
You can install the servers in series or in parallel. To determine which method is best for you, see Table 5-1 and the following sections:
•Serial Installation
•Parallel Installation
Table 5-1 Comparison of Serial and Parallel Cisco TelePresence Exchange System Installation
|
|
|
Serial |
Less opportunity for entry errors. You enter information into the installation wizard for only one server at a time. |
Longer installation process. Each server installation requires 40 minutes to install. So the full serial installation requires 240 minutes (6 servers × 40 minutes each). |
Parallel |
Shorter installation process. Each server pair requires 40 minutes to install. You must install the database servers before you begin to install the administration and call engine servers. Depending on whether you install all four of the administration and call engine servers at the same time, the full parallel installation requires one of the following lengths of time: •120 minutes (3 parallel installations × 40 minutes) •80 minutes (2 parallel installations × 40 minutes) |
Greater opportunity for entry errors. You enter information into the installation wizard for two to four servers at a time. |
Serial Installation
Software installation for each server requires approximately 40 minutes when you employ a serial installation. To ensure the proper exchange of information among the Cisco TelePresence Exchange System servers during a serial installation, install the servers in the following order:
1. Install the primary database server.
2. Install the secondary database server.
3. Install the administration and call engine servers. The order in which you install these remaining nodes does not matter.
See the following sections for detailed installation instructions for each server:
•Installing and Synchronizing the Cisco TelePresence Exchange System Database Servers
•Installing the Cisco TelePresence Exchange System Call Engine Servers
•Installing the Cisco TelePresence Exchange System Administration Servers
Parallel Installation
Note You need one copy of the installation DVD for each server that you plan to install in parallel.
To reduce the overall installation time of the Cisco TelePresence Exchange System servers, you can install the servers in parallel in the following order:
1. Install the primary and secondary database servers in parallel.
Ensure that the database server installations and synchronization are complete before you proceed to install the call engine and administration servers.
2. Install the administration and call engine servers in parallel. You can start the installation for as many servers as you have installation DVDs.
See the following sections for detailed installation instructions for each server:
•Installing and Synchronizing the Cisco TelePresence Exchange System Database Servers
•Installing the Cisco TelePresence Exchange System Call Engine Servers
•Installing the Cisco TelePresence Exchange System Administration Servers
Options for Connecting to the Cisco TelePresence Exchange System Servers for Installation
You have two connection options for running the Cisco TelePresence Exchange System installer on each server:
•Direct connection to the console, for example, through a keyboard-video-mouse (KVM) switch.
•Remote connection by using the integrated management module (IMM) interface. See the "Using the IMM to Remotely Install the Cisco TelePresence Exchange System Software" section.
Note Although you may use the IMM to remotely run the installer, the Cisco TelePresence Exchange System installation DVD must be inserted into the server. Cisco currently does not support full remote installation by mounting the DVD or image file using the IMM.
Using the IMM to Remotely Install the Cisco TelePresence Exchange System Software
Before You Begin
•For each server that you want to access remotely, you must first complete the procedures in the "Setting Up the IMM" section on page 4-7.
•Insert the Cisco TelePresence Exchange System installation DVD into the server. Cisco currently does not support full remote installation by mounting the DVD or image file using the IMM.
•Complete this task by using one of the following web browsers:
–Microsoft Internet Explorer version 6.0 or later with the latest Service Pack
–Mozilla Firefox version 1.5 or later
•Make sure that the browser allows popup windows from the IMM.
Procedure
Step 1 Point your browser to the IP address of the IMM interface.
Step 2 Log in to the IMM web interface.
Step 3 Select Continue.
Step 4 Select System > Tasks > Remote Control.

What to Do Next
Proceed to the "Synchronizing the Database Servers" section.
Related Topics
•Appendix C, "Command Reference"
Synchronizing the Database Servers
When you initiate database synchronization, you enable the heartbeat connection, begin running MySQL (on the primary database server only), and synchronize the data between the two database servers.
Before You Begin
Complete these tasks for both database servers:
•Installing the Database Server Software
•Checking the Initial High-Availability Role of the Database Servers
Procedure
Step 1 Log in to the CLI of the database server that was initially configured with the primary HA role.
Step 2 Enter the utils service database sync command to set up synchronization on the initial primary server.
The synchronization takes approximately 10 minutes and includes a reboot of the secondary database server.
Step 3 Enter the utils service database status command to check the synchronization status of the initial primary server.
After the synchronization process is complete on the initial primary server, the command output will indicate the following items:
•The server currently has the primary HA role.
•The heartbeat is running.
•The connection state (cs) of WFConnection, which is short for "waiting for a connection," indicates that the primary server is waiting for the secondary server to become available on the network.
For example:
admin: utils service database status
--------------------------------------------------------------------------------
The initial configured HA role of this node : primary
The current HA role of this node : primary
The database vip address : 10.22.130.54
The database primary node name : ctx-db-1
The database primary node IP address : 10.22.130.49
The database secondary node name : ctx-db-2
The database secondary node IP address : 10.22.130.57

–Select Test to confirm connectivity to the NTP entries, and then select Proceed.
–Select OK.
Step 12 In the Security Configuration screen, enter the security password, confirm the password, and select OK.
Note You must configure the same security password on all database, administration, and call engine servers. After you configure the security password on a server, you cannot change it without reinstalling the server.
Caution
This is your last chance in the installation wizard to select
Back to verify your entries. Complete the next step only when you are sure that the entries that you made throughout this procedure are correct.
Step 13 In the Platform Configuration Confirmation screen, select OK.
If, in Step 3, you chose to proceed to enter the server information before installing the software, the following information applies:
•The installer spends approximately 30 minutes installing the software.
•If the system has problems with the information that you entered in the installation wizard, you will be prompted to correct the information.
The server ejects the installation DVD and reboots the server while completing the installation. This process takes approximately 10 minutes. When complete, the system prompts you to log in to the CLI.
The installation of Cisco TelePresence Exchange System has completed successfully.

Verifying Data Connectivity Among the Servers
If the Cisco TelePresence Exchange System nodes are unable to properly exchange data, various problems will eventually arise. Complete this task to verify proper data connectivity after you install all six nodes in the Cisco TelePresence Exchange System server cluster or after you reinstall one of the nodes.
Procedure
Step 1 Point a web browser to the following URL, using the IP address of one of the administration servers:
http://ip-address/ctxadmin
Make sure that you are not using the virtual IP (VIP) address that is configured on the Cisco Application Control Engine (ACE).
Step 2 If the login page for the Cisco TelePresence Exchange System administration console does not appear, complete the following steps:
a. Repeat Step 1, but this time use the IP address of the other administration server.
If the login page appears, proceed to Step 3.
b. Make sure that the browser machine can reach other devices in the same VLAN as the administration servers. Resolve any network connectivity issues.
c. The administration server may be configured with an incorrect VIP address for the database servers. Complete the procedure in the "Changing the Database VIP Address That Is Configured on a Call Engine or Administration Server" section on page 28-4.
d. Repeat Step 1.
e. If you still cannot reach the admin console, the security password that you entered while installing the administration server does not match the security password that you entered while installing the the initial primary database server.
To change the security password on a server, you need to reinstall that server. See the "Installing the Cisco TelePresence Exchange System Administration Servers" section.
If reinstalling to change the security password on the administration server does not enable you to reach the admin console, you need to reinstall and change the security password on both database servers. See the "Installing and Synchronizing the Cisco TelePresence Exchange System Database Servers" section.
Step 3 Log in to the administration console with the username admin and the password cisco.
Step 4 Select System > Cluster Nodes.
Step 5 Verify that all six nodes (two database servers, two call engine servers, and two administration servers) appear in the list of cluster nodes.
It may take up to five minutes for a newly installed node to register itself to the database and appear in the list of cluster nodes.
Step 6 If any of the servers remain missing from the list of cluster nodes, you need to reinstall those servers to correct the security password on those servers.
Complete the procedures that are relevant to the servers that are missing from the list of cluster nodes:
•Installing and Synchronizing the Cisco TelePresence Exchange System Database Servers
•Installing the Cisco TelePresence Exchange System Call Engine Servers
•Installing the Cisco TelePresence Exchange System Administration Servers
