Using Dell Update Packages 27
You can define a location to search for available updates from the following
options:
– the Dell File Transfer Protocol (FTP) server ( ftp.dell.com ). You can
use a proxy server to access
ftp.dell.com .
– a USB device. When accessing updates from a local USB device, the
USB device must be plugged in before selecting the
Platform Update
option in USC LCE.
NOTE: See the Dell Unified Server Configurator User Guide available on the
Dell Support website at support.dell.com for more information on updating the
platform.
After you select the updates you want to apply, USC LCE downloads and
applies the updates. If you decide to update any device in USC LCE, the
update package of the corresponding device is downloaded. After successfully
downloading, verifying, and extracting the DUPs, the corresponding devices
are updated. If the update fails, error messages are displayed.
Rollback in USC LCE
You can update any component, for example BIOS, in both USC LCE and
your operating system environment. After the update is successful in your
operating system environment using DUPs, you can enter USC LCE and
revert the component to the version that was previously installed before the
update occurred.
USC LCE supports platform firmware rollback to the previous version. If your
operating system has a non–functioning application because of a BIOS or
firmware flash, reboot to USC LCE and roll back to the previous version.
NOTE: Only BIOS and firmware can be rolled back. The USC LCE application, the
Dell Diagnostics application, and drivers needed for operating system installation
cannot be rolled back to an earlier version.
If you have updated your system’s BIOS or firmware only once, the rollback
feature offers the option of reverting to the factory-installed BIOS or firmware
images. If you have updated your BIOS or firmware to multiple versions, the
factory-installed images are overwritten and you cannot revert to them.
NOTE: Rollback is not supported in your operating system environment. To enable
rollback, ensure that you boot into USC LCE.
