For your convenience, you can install system software and intrusion rule updates as part of the restore process.
For example, you could restore a device to Version 6.0, and also update the device to Version 6.0.0.1 as part of
that process. Keep in mind that only Management Centers require rule updates.
To obtain the restore ISO and other update files:
1.
Using the user name and password for your support account, log into the Support Site
(https://sso.cisco.com/autho/forms/CDClogin.html).
2.
Browse to the software download section (https://software.cisco.com/download/navigator.html).
3.
Enter a search string in the

4.
Find the image (ISO image) that you want to download.
You can click one of the links on the left side of the page to view the appropriate section of the page. For
example, you would click
System.
5.
Click the ISO image you want to download.
The file begins downloading.
6.
Copy the files to an HTTP (web) server, FTP server, or SCP-enabled host that the appliance can access on its
management network.
Caution:
Do not transfer ISO or update files via email; the files can become corrupted. Also, do not change
the names of the files; the restore utility requires that they be named as they are on the Support Site.
Beginning the Restore Process
Begin the restore process by booting the appliance from an internal flash drive.
After you make sure that you have the appropriate level of access and connection to an appliance, as well the
correct ISO image, use one of the following procedures to restore your appliance:
Starting the Restore Utility Using KVM or Physical Serial Port, page 21
process for an appliance where you do not have LOM access.
Starting the Restore Utility Using Lights-Out Management, page 22
process via an SOL connection.
Caution:
The procedures in this chapter explain how to restore an appliance without powering it down.
However, if you need to power down for any reason, use the appliance's web interface, the
command from the CLI on a Firepower device, or the
(sometimes called expert mode).
Starting the Restore Utility Using KVM or Physical Serial Port
For Firepower devices, Cisco provides a restore utility on an internal flash drive.
Note:
Do not use a KVM console with USB mass storage to access the appliance for the initial setup because the
appliance may attempt to use the mass storage device as a boot device.
If you need to restore an appliance to factory defaults and do not have physical access, you can use LOM to
perform the restore process; see
