How to Install Cisco Unified Communications Manager
The installation of the Cisco Unified Communications Manager (CUCM) can seem like a daunting task. This article takes a look at the basic steps required to install the base operating system and the CUCM application on a new device.
Cisco Unified Communications Manager Installation
There are a number of caveats that need to be reviewed before a new CUCM installation. As there is a long list of things to be aware of, the easiest method of review is by reading the sections on these in the Cisco installation guide for the specific version of CUCM that is being installed. This article uses CUCM version 8.6(1) as its source, some steps may be slightly different depending on the version, this installation guide can be found <a href="http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/install/8_6_1/install/cmins861.pdf" title="Installing Cisco Unified Communications
Manager Release 8.6(1)” target=”_blank”>here.
One option that is available is to create an answer file that is used for performing an installation unattended. If this answer file has been already created and copied to a USB key, insert it into the target device.
Insert the installation media into the target device and reboot.
Note: The operating system and CUCM application are installed using the same installation program.
The first thing that is prompted is a media check, this check verifies that the DVD media is intact and has no read problems. If this is the first time the media has been used, performing a media check is cheap insurance that everything will be installed correctly. If the media has been previously verified, this check can be bypassed.
This step checks to ensure that the hardware is correctly configured. Hardware configuration and additional reboots may be required.
The next thing that is prompted is product deployment selection, three options are possible, these include:
- Cisco Unified Communications Manager (CUCM)
- Cisco Unity Connection (CUC)
- Cisco Unified Communications Manager Business Edition 5000
As this article is focused on CUCM, this will be the product to select. Only products that are supported by the current hardware will be selectable.
The next screen is for the Platform Installation Wizard which will prompt to proceed with installation. This screen also offers other methods to proceed including unattended installation and to configure previously installed hardware. Simply select the method that is specific to the installation.
Another secondary step that is available is to upgrade to a more recent service release during the installation. If this is an option that is relevant to this specific installation select yes, the installation will continue on and eventually reboot (at the end of these steps), on reboot an Install Upgrade Retrieval Mechanism Configuration window will display and go through this process.
The next window will prompt for a timezone selection, select the correct timezone for the device.
The installation wizard will then prompt for Ethernet configuration settings including speed and duplex settings. Select either Yes (for autoconfiguration) or No and select the appropriate Ethernet settings.
The next window will prompt for MTU configuration, if the default MTU on the network is different than default then enter the appropriate MTU. Typically, the MTU should be left at the default settings, incorrect configuration can affect network performance.
The next window will prompt for device network addressing configuration, the device can be configured to automatically obtain an address through a Dynamic Host Configuration Protocol (DHCP) server or it can be manually configured.
The next window will prompt for the device Domain Naming System (DNS) configuration information, enter the DNS information for this device. Once this step is complete the device will reboot with the configured settings. After reboot the device, the basic installation of the device will be complete and the specific settings will need to be configured depending on the specific application of the device, for example, is the device stand alone or is it part of a cluster.
Once the basic installation process has been completed the user can then configure the device with the settings specific for install. These options include whether the device will be included as part of a CUCM cluster.
This article reviews the basic steps that must be completed in order to build CUCM. There are a number of different configurations that can then be used to deploy the specific settings required for the specific installation. Hopefully this article can provide a base guideline for those looking to install CUCM in the future.
