Installing and configuring Avaya Enterprise Linux

Last Updated : Jun 05, 2026 |

Before you begin

Install the Avaya-provided hardware at the customer site.

If you install Avaya Enterprise Linux using a direct connection, ensure that you have a keyboard and monitor connected directly to the server machine.

If you use an Ethernet connection from a laptop, ensure you have configured the laptop.

Have the completed Single server configuration worksheet ready to help answer the questions raised during the installation.

Important:

Installation of Avaya Enterprise Linux erases any existing data on the server. Ensure that you do not need any old data before you install.

Procedure

  1. Insert the Enterprise Linux Installer DVD into the DVD drive.
  2. Reboot the server so that the server boots from the Enterprise Linux Installer software.
  3. If you install from the console:
    1. In the Avaya Enterprise Linux installer Welcome screen, type 1 and press Enter at the boot prompt to select the Fresh Install option.
      Important:

      You must enter your selection in the Welcome screen within 60 seconds. Otherwise, the installer runs a search function to locate an Ethernet connection on the eth1 interface.

    The system displays the file transfer message, and then the Warning screen.

  4. If you install on a laptop through an Ethernet connection to eth1:
    1. On a command line, enter the ping -t 192.11.13.6 command to determine when the server completes the reboot.
    2. After the screen displays the response from the server, type Ctrl+C to stop the ping command.
    3. Open a Telnet client, such as PuTTY, and connect to the IP address 192.11.13.6.
      Note:

      The default client is SSH. Ensure that you select telnet.

    Important:

    Initiate the telnet session within 5 minutes of the server responding to the ping command. If you do not initiate the telnet session, the installer ejects the DVD and reboots the server.

    Note:

    To use the Windows command telnet as the telnet client:

    • Enter the telnet command.

    • At the Microsoft Telnet> prompt, enter the set term vt100 command.

    • At the Microsoft Telnet> prompt, enter the open 192.11.13.6 command.

    Note: When using telnet connection, the install screen might not display the information clearly.

    The system displays the file transfer message and then the Warning screen.

  5. On the Warning screen, type Yes and press Enter to continue with the installation.
    Note:

    Instead of displaying the Warning screen, the system might display the No Disks found! /dev/sda missing error. To resolve this error, type n and press Enter at the Eject CD/DVD before rebooting prompt.

    The system displays the Network-related information screen.

  6. Enter the following details on the Network-related information screen:

    • Hostname or FQDN: Type the hostname of the server.

    • IP Address (eth0): Type a static IP address of the server.

    • SubNetmask : Type the subnet mask of the server.

    • Gateway: Type the IP address of the gateway.

    • DNS Domain : Type the domain name of the server.

    • DNS Server 1: Type the IP address of the first DNS server.

    • DNS Server 2: Type the IP address of the second DNS server.

    • DNS Server 3: Type the IP address of the third DNS server.

  7. Press Enter.

    The system displays the network related information that you have entered.

  8. Type Yes and press Enter to confirm the network related information.

    The system displays the Time Zone selection screen.

  9. Type the required option and press Enter to select a region.

    The system displays the list of corresponding time zones.

  10. Type the required option and press Enter to select a time zone.

    The system displays the time zone information that you have specified.

  11. Type c and press Enter to confirm the details.

    The system displays the Date and Time screen.

  12. Specify the date details:

    • day of month

    • month

    • year

  13. Specify the time details:

    • hours

      Note:

      Type the hour in 24-hour format.

    • minutes

  14. Press Enter.

    The system displays the Date and Time that you have specified.

  15. Type yes and press Enter to confirm the date and time information.

    The system displays the NTP Configuration screen.

  16. On the NTP Configuration screen, enter the following details:

    • NTP server 1: Type the IP address of the first NTP server.

    • NTP server 2: Type the IP address of the second NTP server.

    • NTP server 3: Type the IP address of the third NTP server.

    Note:

    You can leave all the NTP server addresses blank as the Experience Portal system automatically configures NTP on all servers, other than the primary EPM, to synchronize with the primary EPM.

  17. Press Enter.

    The system displays the NTP information that you have specified.

  18. Type yes and press Enter to confirm the NTP details.

    The system erases all existing data, and installs Avaya Enterprise Linux. When the installation is complete, the system ejects the DVD and reboots the server.

    Important:

    Once the server reboots, you can no longer access the server remotely through telnet. You must use an SSH client, such as PuTTY.

    PuTTY can function as an SSH client as well as a telnet client.

  19. Remove the Avaya Enterprise Linux DVD from the DVD drive.

    The installation is complete.

  20. Optional Log in to Linux on the Experience Portal server after the server reboots.

    The Enterprise Linux Installer creates craft and sroot accounts but they are disabled with no predefined password. The craft and sroot accounts are Avaya Service Accounts and can only be enabled via EASG control. You should use the cust and root accounts to login to the server. Avaya Enterprise Linux has assigned a default password for both accounts.

    For more details, see State of identity variables in Master Software Image and on first boot.

    Note:

    • You cannot log in directly as a root user except through the console. Log in as a non-root user and switch to a root account using the su — command.

    • If you install from the console, log in to the local Linux console as root.

    • If you install through an Ethernet connection to eth1:

      • Use a secure shell (SSH) client, such as PuTTY, to open an SSH connection to the 192.11.13.6 IP address.

      • Log in to Linux as cust and enter the su — command to change to the user root.

Next Steps

Install the Experience Portal software as described in the Implementing Avaya Experience Portal on multiple servers or Implementing Avaya Experience Portal on a single server.
