Cisco Firepower Threat Defense for Firepower 4100 Quick Start Guide

Delete Existing Logical Devices and Application Configurations

To upgrade a Firepower Threat Defense logical device or to deploy a different logical device, you must delete the 
existing device and then create a new one using the updated image. If you are upgrading both the FXOS platform 
bundle image and an application, you must upgrade the FXOS platform bundle first.

From the Firepower Chassis Manager interface, choose Logical Devices to open the Logical Devices page. 

The Logical Devices page shows a list of configured logical devices on the chassis. If no logical devices have 
been configured, a message stating so is shown instead. 

Click the Delete icon associated with each logical device. 

Click Yes when prompted to delete the logical device. 

Click Yes when prompted to delete the application configuration. This final step is necessary for a successful 
installation of Firepower Threat Defense.



Check the running version of the Firepower FXOS software running on the chassis to determine if it needs to 
be upgraded to support running Firepower Threat Defense or any other application on the security engine.

Upgrade the Firepower Supervisor Platform

The running version of FXOS is displayed at the top of the Overview page on the Firepower Chassis Manager web 
interface. You need to determine if the current version of the FXOS running on the chassis is sufficient to support 
running your application on the security engine. You upgrade the FXOS platform bundle from the Updates page of 
the System menu.

From the Firepower Chassis Manager interface, choose System > Updates. The Available Updates page 
shows a list of the Firepower 4100 platform bundle images and application images that are available on the 
chassis. 

Browse the Image Name column to locate the FXOS platform bundle you need to load. 

Click the upload/download icon associated with the FXOS platform bundle you need to load. 

Click Yes on the Update Bundle Image dialog for the selected version. When you click yes, the selected 
version will be installed and the device will reboot.

6. Access the Firepower Threat Defense CLI

For initial configuration or for troubleshooting, you can access the Firepower Threat Defense CLI from the 
Firepower 4100 FXOS supervisor CLI. 

Connect to the supervisor CLI, either from the console port or using SSH, for example.

Connect to one of the security modules.
