Installation Scenarios
Unified CCX installation has the following installation options:
- Standard installation - This option allows you to install Unified CCX software from the installation disc.
Note
- Configure Network, DNS, Timezone, SMTP and other settings by following on-screen instructions
- Configure nodes using Unified CCX Administration interface, see PostInstallation Tasks
- Unattended installation - This option allows you to use the installation disc and a preconfigured USB disk to install Unified CCX software unattended.
- Virtualization - Unified CCX supports installation on a virtual machine. For more information, see the Virtualization wiki at http://docwiki.cisco.com/wiki/Virtualization_for_Unified_CCX.
System Requirements
For information about system requirements, see the Cisco Unified Contact Center Express Software and Hardware Compatibility Guide at http://www.cisco.com/en/US/products/sw/custcosw/ps1846/products_device_support_tables_list.html.
Important Considerations Before Installation
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 It also upgrades the system BIOS, firmware, and Redundant Array of Inexpensive Disks (RAID) configuration if they are outdated.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.
- 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.
Preinstallation Tasks
Procedure
Step 1 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 second node.
Note If the first node fails to synchronize with an NTP server, installation of a second node also fails.
Step 2 If the firewall is in the routing path, disable the firewall between nodes. Increase the firewall timeout settings until you complete the installation. Step 3 Record the network interface card (NIC) speed and duplex settings of the switch port to which you will connect the new server. Step 4 Enable PortFast on all switch ports that are connected to Cisco servers.
Caution Do not run Network Address Translation (NAT) or Port Address Translation (PAT) between Unified CCX nodes.
Step 5 Obtain a license file. For more information, see Obtain License MAC Before Installation. Step 6 If you choose to apply a patch during installation, use a Secure File Transfer Protocol (SFTP) server that is certified by Cisco through the Cisco Technology Developer Partner program (CTDP). For more information about Supported SFTP Servers, see section "System Requirements" in Cisco Unified Contact Center Express Disaster Recovery System Administration Guide Release 9.0(1) at http://www.cisco.com/en/US/docs/voice_ip_comm/cust_contact/contact_center/crs/express_9_0/configuration/guide/UCCX_BK_D9AB2A78_00_disaster-recovery-system-for-uccx.pdf.
