Unified CCX installation has the following installation options:
Standard installation - This option allows you to install Unified CCX software from the installation disc.
Factory installation - This option allows you to obtain Cisco Media Convergence Server hardware from Cisco, preinstalled with Unified CCX software. Upon receiving the server, power on it and configure appropriately to complete the installation.
Perform the following configurations after the factory installation:
Configure Network, DNS, Timezone, SMTP and other settings by following on-screen instructions
Read the following information carefully before you proceed with the installation:
DNS configuration and domain fields are mandatory for Unified CCX installation. Both forward and reverse lookups are required. DNS is required for the VoIP Monitor Subsystem and Unified CCX Chat feature to function and for integration with ICM by hostname in Unified IP IVR.
When you Install Unified CCX on an existing server formats the hard drive, it overwrites all existing data on the drive. It also upgrades the system BIOS, firmware, and Redundant Array of Inexpensive Disks (RAID) configuration if they are outdated.
Ensure that you connect each Unified CCX node to an uninterruptible power supply (UPS) to protect the Unified CCX server from unexpected power failure that damages the physical media.
Install Unified CCX only on virtual machines. Unified CCX will not run on bare metal.
All servers in a cluster must run the same release of Unified CCX. The only exception is while upgrading cluster software, during which a temporary mismatch is allowed.
Configure the server by using a static IP address so that the server IP address remains unchanged.
Do not attempt to perform any configuration tasks during the installation.
Be aware that the field values (namely hostname and passwords) that you enter while you are running the installation program are case sensitive.
When you insert or remove a USB drive, you might see error messages on the console similar to "sdb: assuming drive cache: write through." You can safely ignore these messages.
If the system time is from an Network Time Protocol (NTP) server (mandatory
for VMware deployments), verify that the first node synchronizes with the NTP server before you install a
If the first node fails to synchronize with an NTP server, installation of a second node also fails.
If the firewall is in the routing path, disable the firewall
between nodes. Increase the firewall timeout settings until
you complete the installation.
Record the network interface card (NIC) speed and duplex settings of the switch port to which you will connect the new server.
Enable PortFast on all switch ports that are connected to Cisco
Do not run Network Address Translation (NAT) or Port Address
Translation (PAT) between
Unified CCX nodes.
