34 USC and USC - LCE
Important
• 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.
• A NIC wrapper.efi error may be displayed if you try updating the NIC
using platform update in USC without the latest versions of iDRAC and
BIOS. Upgrade to the latest BIOS and iDRAC versions to ensure this error
does not occur.
CAUTION: While using USC to update the power supply unit firmware, the system
will shut down after the first task. It will take a couple of minutes to update the
PSU firmware and then automatically power on.
Rolling Back to Previous BIOS and Firmware Versions
USC - LCE enables you to roll back to a previously-installed version of
BIOS or firmware. It is recommended that you use this feature if you have
a problem with the currently-installed version and want to revert to the
previously-installed version.
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.
Important
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.
