About this task

You must acquire entitlement to a QRadar Software Node for a QRadar software installation. To acquire entitlement to a QRadar Software Node, contact your QRadar Sales Representative.

If there are circumstances where you need to install RHEL separately, proceed with the following instructions. Otherwise, proceed to Installing a QRadar appliance.


  1. Map the ISO to a device for your appliance by using the Integrated Management Module (IMM) or the Integrated Dell Remote Access Controller (iDRAC), or insert a bootable USB drive with the ISO.
  2. Insert the portable storage device into your appliance and restart your appliance.
  3. From the starting menu, do one of the following options:
    • Select the device that you mapped the ISO to, or the USB drive, as the boot option.
    • To install on a system that supports Extensible Firmware Interface (EFI), you must start the system in legacy mode.
  4. When prompted, log in to the system as the root user.
  5. Follow the instructions in the installation wizard to complete the installation:
    1. Set the language to English (US).
    2. Click Date & Time and set the time for your deployment.

    6. Select LVM from the list.
    7. Click the Add button to add the mount points and capacities for your partitions, and then click Done. For more information about RHEL7 partitions, see Linux operating system partition properties for QRadar installations on your own system.
      To encrypt data complete the following steps:
      1. Select one of the LVM partitions created.
      2. Select Modify under the Volume Group section. A pop up console opens for further configuration options.

    12. On the IPv4 Settings or IPv6 Settings tab, select Manual in the Method list.
    13. Click Add.
      • For an IPv4 deployment, enter the IP address, Netmask, and Gateway for the appliance in the Addresses field.
      • For an IPv6 deployment, enter the IP address, Prefix, and Gateway in the Addresses field.
    14. Add two DNS servers.
    15. Click Save > Done > Begin Installation.
