22 Using Dell Update Packages
Stand-alone Systems and Firewalls
For systems that are not connected to the Internet or that have firewalls
which block user downloads, you need to download your DUP from
support.dell.com by using a system that does have access to the Internet,
such as your desktop or portable computer. You can make DUP available to
your system by copying them onto removable media that your system supports.
Confirming the Update
To ensure that DUPs were applied to your system, review the console output
that was generated during execution. See "Linux Troubleshooting" on page 41
for detailed information about the messages.
If you want to revert to a previous (older) version of the software after
updating to a newer version, you must download the appropriate DUP from
support.dell.com and install it.
For Linux:
To install the previous version from a script, use -q (unattended) mode. In
addition, you must use the CLI -f option, which forces the downgrade.
NOTE: If your system loses power during the update process, you must perform the
updates again.
NOTE: DUPs for Linux can also be found in the repository on the Dell Server
Updates DVD that contains the updated BIOS, and firmware components for Dell
systems. For more information, see the
Server Update Utility User's Guide available
at support.dell.com/manuals.
For Windows:
To install the earlier version from a script, use the /s (unattended) mode. In
addition, you must use the CLI /f option, which forces the downgrade. To
install the earlier version from the GUI, you are prompted to ensure that you
want to install an earlier version.
