DUPs are available for the following software components:
- System BIOS
- System firmware
- Device drivers
Using DUPs, you can update a wide range of system components simultaneously and apply scripts to similar sets of Dell systems to bring the system components to the same version levels.
You can use DUPs to:
- Apply an individual update to a system by using an interactive command line interface (CLI).
- Install device drivers in interactive and non-interactive modes.
- Execute multiple updates for your system.
- Leverage your operating system's scheduling and software distribution utilities to apply updates remotely to any number of systems.
- Leverage Dell tools such as iDRAC, Dell System Update, Dell Server Update Utility and OpenManage Enterprise to facilitate the application of update packages.

Each Dell Update Package (DUP) software package is digitally signed by Dell using SHA256 or greater.
- Each Dell Update Package is authenticated by validating the DUP hash and DUP digital signature.

Using Dell tools such as Dell Repository Manager (DRM) to identify and gather DUP packages provides and additional level of verification. DRM will not download a DUP that does not have a valid Dell signature nor will it allow the manual import of DUP into a Repository that does not have a valid Dell signature.
