Note that the restore utility will also look for update files in the ISO image directory.
To specify the restore files’ location and transport method:
1. From the main menu, select
2 Choose the transport protocol
.
2. On the page that appears, select either HTTP , FTP , or SCP .
3. Use the series of pages presented by the restore utility to provide the necessary information for the protocol
you chose, as described in
Table 3 .
If your information was correct, the appliance connects to the server and displays a list of the Cisco ISO
images in the location you specified.
4. Select the ISO image you want to use.
5. When prompted, confirm your settings.
6. Do you want to install a system software or intrusion rule update as a part of the restore process?
— If yes, continue with the next section, Updating System Software and Intrusion Rules During Restore .
— If no, continue with Downloading the ISO and Update Files and Mounting the Image, page 27 . Note that
you can use the system’s web interface to manually install updates after the restore process completes.
Updating System Software and Intrusion Rules During Restore
Optionally, you can use the restore utility to update the system software and intrusion rules after the appliance is
restored to the base version in the ISO image. Note that only Management Centers require rule updates.
The restore utility can only use one system software update and one rule update. However, system updates are
cumulative back to the last major version; rule updates are also cumulative. Cisco recommends that you obtain
the latest updates available for your appliance; see
Obtaining the Restore ISO and Update Files, page 20 .
If you choose not to update the appliance during the restore process, you can update later using the system’s web
interface. For more information, see the release notes for the update you want to install, as well as the Updating
System Software chapter in the
Firepower Management Center Configuration Guide .
