3.
Confirm that you want to restore the appliance and continue with the next step.
4.
Choose whether you want to delete the appliance's license and network settings.
In most cases, you do not want to delete these settings, because it can make the initial setup process shorter.
Changing settings after the restore and subsequent initial setup is often less time consuming than trying to
reset them now. For more information, see
Caution:
When restoring FMC models 750, 1500, or 3500 to factory settings using LOM, if you do not have
physical access to the appliance and you delete the license and network settings, you will be unable to
access the FMC after the restore.
Caution:
When restoring FMC models 2000 or 4000 to Version 6.3+ using LOM, if you do not have physical
access to the appliance and you delete the license and network settings, you will be unable to access the
FMC after the restore.
5.
Type your final confirmation that you want to restore the appliance.
The final stage of the restore process begins. When it completes, if prompted, confirm that you want to reboot
the appliance.
Caution:
Make sure you allow sufficient time for the restore process to complete. On appliances with internal
flash drives, the utility first updates the flash drive, which is then used to perform other restore tasks. If you
quit (by pressing Ctrl + C, for example) during the flash update, you could cause an unrecoverable error. If
you think the restore is taking too long or you experience any other issues with the process, do not quit.
Instead, contact Support.
Note:
Reimaging resets appliances in bypass mode to a non-bypass configuration and disrupts traffic on your
network until you reconfigure bypass mode. For more information, see

What to Do Next

Saving and Loading Restore Configurations
You can use the restore utility to save a restore configuration to use if you need to restore a Firepower device again.
Although the restore utility automatically saves the last configuration used, you can save multiple configurations,
which include:
network information about the management interface on the appliance; see
Management Interface, page 30
the location of the restore ISO image, as well as the transport protocol and any credentials the appliance
needs to download the file; see
the system software and intrusion rules updates, if any, that you want to apply after the appliance is restored
to the base version in the ISO image; see
page 31
SCP passwords are not saved. If the configuration specifies that the utility must use SCP to transfer ISO and other
files to the appliance, you will have to re-authenticate to the server to complete the restore process.
The best time to save a restore configuration is after you provide the information listed above, but before you
download and mount the ISO image.
To save a restore configuration:
1.
From the restore utility main menu, select
The utility displays the settings in the configuration you are saving.
