The information in this document was created from the devices in a specific lab environment. All of the devices used in this document started with a cleared (default) configuration. If your network is live, ensure that you understand the potential impact of any command.

Reimage Process

Caution: Do not insert a USB storage device or plug a Keyboard, Video, and Mouse (KVM) switch when you upgrade or reimage a FireSIGHT Management Center or a FirePOWER appliance.

Before You Begin

1. If you plan to reimage a Management Center or stand-alone Firepower device, it is recommended to back up your appliance before you proceed.

2. Identify the model of your sensor and use the list of models in the Components Used section in order to verify that this guide is appropriate.

3. Download the appropriate installation guide and disk image for your desired software version from the Cisco Support site.

Note: Do not rename an .iso file

Serve the image: The .iso file must be copied to a host that runs an SSH server reachable from the management network of the appliance to be reimaged.

Note: If no other SSH server is available, an FMC can be used for this process.

Verify the integrity of the iso: The md5sum of the files are provided on the right-hand side of the page for verification with an md5sum utility.

4. The installation guides contain step-by-step reimage instructions and also outlines several methods for the reimage process. The images provided in this document can be used for reference.

Overview of the Reimage Process

Note: The 5.3 version was used to capture the images shown in this article. The reimage process is identical for other 5.x versions except for the version numbers that appear in the images shown.

Figure 2 - When the system reboots, press an arrow key on the keyboard in order to halt the countdown to choose the System_Restore option for the screen depicted next.

Note: If the System_Restore prompt does not display, you must change the boot order to boot directly to the Restore partition (DOM). For more information, see System_Restore LILO menu option is missing.

Figure 3

Figure 4 - Choose option 0 if you use a keyboard and monitor.

Note: Sometimes it has been seen that the menu for the Restore option is only shown when only the Console is connected (with the Keyboard unplugged). As soon the Recovery option is selected, the keyboard can be connected back again

Figure 15 - Cisco Support recommends that you use the Secure Copy (SCP) protocol.

Figure 16 - It is possible to use a FireSIGHT Management Center as the SCP server for this step. Continue with this procedure and use the IP address and credentials for the Management Center in order to populate the fields in the System Restore menu. More details in

A Secure Copy (SCP) server is used to transfer files securely. If necessary, a Sourcefire Defense Center (DC) can be used as an SCP server to transfer files to another Sourcefire device. This can be useful when an iso image needs to be transferred to a Sourcefire device for reimage purposes, but the regular SCP server is unreachable or unavailable.

Step 1. Download an appropriate .iso file to your desktop from the Sourcefire Support Portal.

Step 2. Use an SCP client, copy the file from the desktop to the Defense Center.

Tip: An SCP client is usually available in a Linux or Mac Operating System. However, in Windows operating system, you can have to install a third-party SCP client software. Sourcefire does not provide recommendations or support to install any specific SCP client software.

The next example demonstrates how to copy a Sourcefire .iso image file from the Downloads directory of a Linux system to the /var/tmpdirectory of the Sourcefire Defense Center:

LinuxSystem:~$ cd Downloads

LinuxSystem:~/Downloads$ scp Sourcefire_3D_Sensor_S3-4.10.2-Restore.iso user_name@IP_Address_of_Defense_Center:/var/tmp

Caution: Do not change the name of the .iso file. It can create an issue with the detection of the file during a reimage.

Now the file is copied to the Defense Center. You can proceed with the reimage process of Sourcefire devices. At the reimage, when necessary, you can provide the IP address and user name of the DC and the path where you copied the image file with the previous instructions.

Warning: After completes the reimage, you must remove the .iso file from the /var/tmp directory of the Defense Center to reduce the utilization of the disk space.

Note: If you receive a connectivity error at this point instead of the expected message, verify your connection to the SSH server.

Figure 20 - In order to select the .iso image, press the spacebar.

Note: It is required to use the default filenames for the .iso files or the files are possibly undetected at this step.

Error: No ISO Image Were Found

In Version 6.3 the ISO name convention have changed from Sourcefire_3D_Device_S3-<ver>-<build>-Restore.iso to Cisco_Firepower_NGIPS_Appliance-<ver>-<build>-Restore.iso. If you encounter "No ISO Image Were Found", rename the ISO file to the legacy filename. This normally happens when a re-image of 6.2.x or older version to 6.3.0 or later version.

Figure 21

Figure 22 - Cisco Support recommends to skip step 3 in this process. Patches and Snort Rule Updates (SRUs) can be installed after the reimage is complete.

Important note in regards to a reimage from a different major software version: If you attempt to reimage a device that previously ran a different major software version, such as if you reimage 5.1 > 5.2, 5.2 > 5.3, 5.3 > 5.2, and so on, you must complete the steps depicted in Figures 1 - 26 twice.

1. After you choose OK on the prompt as shown in the image 26, the System Restore partition is flashed to the new version and the appliance reboots.

2. After the reboot, you must begin the reimage process again from the start and continue through the process depicted in Figures 27b through 31.

If this is the first reimage from a different major software version, you see the screen as shown in the image 27a, and then Figures 31 and 32.

Caution: If you see this screen, there is a possible delay with no visible output after "Checking Hardware" and before "The USB device...". Do not press any keys at this time, or the device reboots into an unusable state and needs to be reimaged once more.

If this is not the case, you can see the screens in Figure 27b through Figure 32.

Cisco Firepower Management Center 1000, 2500, and 4500

On FMC 1000, 2500, and 4500 the options are different. Use a KVM switch or the CIMC and while the device starts, you are presented with these options:

1 - Cisco Firepower Management Console VGA Mode

2 - Cisco Firepower Management Console Serial

3 - Cisco Firepower Management Console System Restore Mode

4 - Cisco Firepower Management Console Password Restore Mode

If you want to enter the Restore Mode with UI select the option 'Cisco Firepower Management Console System Restor Mode' (option 3) and then 'Cisco Firepower Management Console System Restore VGA Mode' (option 1

Figure 33

The rest of the process is the same as on other FMC appliances.
