Avaya Contact Center – Extended Capacity server software requires a Red Hat® Enterprise Linux® (RHEL) 8.10. You must install the required operating system on all contact center servers.
You can make Avaya Contact Center – Extended Capacity Federal Information Processing Standard (FIPS) compliant by installing your operating system with the FIPS mode enabled. For more information about enabling FIPS mode while installing the operating system, see the topic related to switching RHEL to FIPS mode at https://access.redhat.com/.
For more information about operating system installation, see the RHEL documentation at https://access.redhat.com/.
Before you begin
  • If you deploy the Configuration Server on a virtual machine, create a virtual machine using the corresponding hypervisor management application.
  • For the deployment on Dell servers, configure iDRAC. For more information about the iDRAC configuration, see the iDRAC documentation at https://www.dell.com/support/.
  1. Obtain the installation file for the required operating system.
  2. Connect a monitor, a keyboard, and a computer mouse to your server or virtual machine hardware.
  3. Turn on or restart the server.
    ADDITIONAL INFORMATION:
    Note:
    To install operating system with the FIPS mode enabled, go to https://access.redhat.com/ and navigate to the topic related to switching RHEL to FIPS mode.
    ADDITIONAL INFORMATION:
    Warning:

  4. Install the operating system with minimal configuration.
    ADDITIONAL INFORMATION:
    For more information about operating system installation on Dell servers, see https://www.dell.com/support/.
  5. To ensure data privacy, enable disk encryption.
  6. Configure disk partitioning.
  7. Set a root password.
  8. Configure an administrator account.
    ADDITIONAL INFORMATION:
    For deployment, you must create a mega user account with the sudo access. You can also create a mega user after the operating system installation.
  9. Specify the home directory for your administrator account.
  10. Assign traffic VLAN IP addresses to the appropriate network interfaces.
    ADDITIONAL INFORMATION:
    You can also assign traffic VLAN IP addresses after the operating system installation using CLI commands.

    ADDITIONAL INFORMATION:
    Avaya Contact Center – Extended Capacity does not currently use standard syslog facilities or store log files on the rsyslog server. The contact center generates Docker container and service log files to record contact center events. For more information about the contact center log processing, see the data privacy and security section in Maintaining Avaya Contact Center – Extended Capacity.
