2 Click Apply .
NOTE: The system reboots after the update process is complete. When applying
more than one update, the system may need to reboot between updates. In this
case, the system boots directly into USC - LCE and continues the update process.
No action on your part is required when the system reboots to complete the
update process.
NOTE: If the iDRAC firmware update is interrupted for any reason, you may need
to wait for up to 30 minutes before attempting another firmware update.
NOTE: USC-LCE does not support the update or rollback of PERC 5/E Adapter for
external storage, SAS 5i/R Adapter for tape, PERC S100 and PERC S300 Adapters,
and Intel™ NIC Adapters.
Rolling Back to Previous BIOS and Firmware Versions
USC - LCE enables you to roll back to a previously-installed version of
BIOS or firmware. Dell recommends that you use this feature if you have
a problem with the currently-installed version and want to revert to the
previously-installed version.
NOTE: Only BIOS and firmware can be rolled back. USC - LCE, the hardware
diagnostics application, and drivers needed for operating system (OS) installation
cannot be rolled back to earlier versions.
This feature is available only if you have used the USC - LCE update feature
to update BIOS and firmware, or if you have updated the system BIOS or
firmware using a post-operating system Dell Update Package. If you have
used other update methods, this feature is not available.
NOTE: Power supply firmware does not support creation of a rollback image if it is
updated using a post-operating system Dell Update Package.
NOTE: 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 more than once, the
factory-installed images are overwritten and you cannot revert to them.
Launch the Rollback Wizard
1 Boot your system to launch USC - LCE. When the Dell logo displays,
press the
<F10> key within 10 seconds.
2 Click Platform Update in the left pane.
3 Click Launch Platform Rollback in the right pane.
