|Bundle Download Mechanism||You obtain software upgrade bundles from Teradata Support at https://access.teradata.com.|
|Operating System Updates||Because the operating system software bundle includes both important security updates and the latest version of the utility used to upgrade Teradata components (PUT), you must download this bundle whenever upgrading other Teradata components with the exception of Server Management, for which the required updates are included in the image itself.|
|Outage Preparation||When upgrading the operating system and Teradata components including Server Management, PUT does not set a maintenance window, but does automatically reboot the system. Be sure to plan accordingly.|
