Obtaining The Restore Iso And Update Files - Cisco Firepower 8120 Getting Started Manual

Note that you cannot restore an appliance using its web interface. To restore an appliance, you must connect to
it in one of the following ways:
Keyboard and Monitor/KVM
You can connect a USB keyboard and VGA monitor to the appliance, which is useful for rack-mounted
appliances connected to a KVM (keyboard, video, and mouse) switch. If you have a KVM that is
remote-accessible, you can restore appliances without having physical access.
Serial Connection/Laptop
You can use a rollover serial cable (also known as a NULL modem cable or a Cisco console cable) to connect
a computer to the appliance. See the hardware specifications for your appliance to locate the serial port. To
interact with the appliance, use terminal emulation software such as HyperTerminal or XModem.
Lights-Out Management Using Serial over LAN
You can perform a limited set of actions on Management Centers and Firepower devices using Lights-Out
Management (LOM) with a Serial over LAN (SOL) connection. If you do not have physical access to an
appliance, you can use LOM to perform the restore process. After you connect to an appliance using LOM,
you issue commands to the restore utility as if you were using a physical serial connection. Note that you can
use Lights-Out Management on the default (

Obtaining the Restore ISO and Update Files

Cisco provides ISO images for restoring appliances to their original factory settings. Before you restore an
appliance, obtain the correct ISO image from the Support Site.
The ISO image you should use to restore an appliance depends on when Cisco introduced support for that
appliance model. Unless the ISO image was released with a minor version to accommodate a new appliance
model, ISO images are usually associated with major versions of the system software (for example, 5.2 or 5.3).
To avoid installing an incompatible version of the system, Cisco recommends that you always use the most recent
ISO image available for your appliance.
Firepower devices use an internal flash drive to boot the appliance so you can run the restore utility.
Cisco also recommends that you always run the latest version of the system software supported by your appliance.
After you restore an appliance to the latest supported major version, you should update its system software,
intrusion rules, and Vulnerability Database (VDB). For more information, see the release notes for the update you
want to apply, as well as the Firepower Management Center Configuration Guide.
