The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Perform all pre-installation tasks to ensure that you can successfully install the Cisco Unified Communications Manager (Unified Communications Manager).
Step 1 | Review the installation requirements and record the configurations settings for each server that you plan to install. | ||||
Step 2 | For every node
in your cluster, create virtual machines using the Virtual Server Template (OVA
file) recommended for your current release.
Different OVA files are available; choose the correct OVA file based on the environment in which you are deploying Cisco Unified Communications Manager. | ||||
Step 3 | Place the installation ISO file in a location where the virtual machine can access it and edit the virtual machine's DVD drive to map to the file. Select the option to mount the DVD drive when you power on the virtual machine. When you power on the virtual machine, it will mount the ISO file and start the installation process. Do not begin the installation process until you have completed all of the steps in this procedure. | ||||
Step 4 | If you are installing a cluster or adding a node, verify that the links between servers meet the 80-ms round-trip time (RTT) requirement and that you have enough bandwidth to support database replication. For more information on the 80-ms RTT requirement, refer to the Cisco Unified Communications Solution Reference Network Design (SRND) based on Cisco Unified Communications Manager, which you can find at http://www.cisco.com/en/US/products/sw/voicesw/ps556/products_implementation_design_guides_list.html. | ||||
Step 5 | If you are
getting the system time from an NTP server (mandatory for VMware deployments),
verify that the publisher node can synchronize with the NTP server before you
install a subscriber node. Log into the Command Line Interface on the publisher
node and enter the following command:
utils
ntp status
For more information, see the Command Line Interface Reference Guide for Cisco Unifed Communications Solutions.
| ||||
Step 6 | If your firewall is in the routing path, disable the firewall between nodes, if possible. Also, increase the firewall timeout settings until after you complete the installation. To temporarily allow network traffic in and out of the nodes (for example, setting the firewall rule for these nodes to IP any/any) does not always suffice. The firewall might still close necessary network sessions between nodes due to timeouts. | ||||
Step 7 | Do not run Network Address Translation (NAT) or Port Address Translation (PAT) between servers where you are installing Cisco Unified Communications Manager. | ||||
Step 8 | Ensure that the
network interface card (NIC) speed and duplex settings on the switch port are
the same as those that you plan to set on the new server.
For GigE (1000/FULL), you should set NIC and switch port settings to Auto/Auto; do not set hard values. | ||||
Step 9 | Enable PortFast on all switch ports that are connected to Cisco servers. With Portfast enabled, the switch immediately brings a port from the blocking state into the forwarding state by eliminating the forwarding delay [the amount of time that a port waits before changing from its Spanning-Tree Protocol (STP) learning and listening states to the forwarding state]. | ||||
Step 10 | If you use DNS, verify that all servers on which you plan to install Cisco Unified Communications Manager are properly registered in DNS. | ||||
Step 11 |
If you are using a server that is running VMware
EX/ESXi and the motherboard has an ICH10 onboard SATA controller, you must
disable the SATA controller in the BIOS. The ICH10 onboard SATA controller is
not supported by EX/ESXi.
| ||||
Step 12 | Obtain a
license file.
| ||||
Step 13 | Configure any subscriber nodes on the publisher node before you install a subscriber node. From Cisco Unified CM Administration on the publisher node, choose and configure the IP address for the subscriber nodes. For more information, see the Administration Guide for Cisco Unified Communications Manager. |
You must complete the following pre-installation tasks before you begin to install the IM and Presence software.
Follow this procedure if you use a DNS in your topology. You must verify that all servers to be added are registered in DNS properly by performing the following actions:
The following procedure describes how to generate an answer file using the Cisco Unified Communications Answer File Generator.
Gather the required installation and configuration information.
Step 1 | Access the Cisco Unified Communications Answer File Generator at the following URL: http://www.cisco.com/web/cuc_afg/index.html. | ||
Step 2 | Enter the required information for the node(s) that you wish to
install.
You can specify installation and configuration information for the publisher node and up to 5 subscriber nodes in a cluster.
| ||
Step 3 | Select Generate Answer Files. | ||
Step 4 | Follow the instructions to download the answer file(s).
A separate answer file will be generated for each node that you want to install and configure. |
You may need to reformat the USB key for the answer file to the FAT32 file system using the Windows XP Disk Management Utility. The FAT file system format provides for larger storage capacity (for example, 1 Gigabyte). You may need to be an Administrator or a member of the Administrators group to perform this procedure.
Step 1 | Insert the USB key into a USB slot on the Windows XP computer. |
Step 2 | Select Computer Management. and double-select |
Step 3 | Expand the Storage tree and select Disk Management. |
Step 4 | Right-click the Removable Disk icon and select Format. |
Step 5 | Select Yes if you are asked whether you are sure that you want to format this partition. |
Step 6 | Select the File System and select FAT32 from the list box. . |
Step 7 | Select OK and OK again when you are prompted to format the volume. |
