About Image Management
The Firepower 4100/9300 chassis uses two basic types of images:
Note |
All images are digitally signed and validated through Secure Boot. Do not modify the image in any way or you will receive a validation error. |
-
Platform Bundle—The Firepower platform bundle is a collection of multiple independent images that operate on the Firepower Supervisor and Firepower security module/engine. The platform bundle is a Firepower eXtensible Operating System software package.
-
Application—Application images are the software images you want to deploy on the security module/engine of the Firepower 4100/9300 chassis. Application images are delivered as Cisco Secure Package files (CSP) and are stored on the supervisor until deployed to a security module/engine as part of logical device creation or in preparation for later logical device creation. You can have multiple different versions of the same application image type stored on the Firepower Supervisor.
Note |
If you are upgrading both the Platform Bundle image and one or more Application images, you must upgrade the Platform Bundle first. |
Note |
If you are installing an ASA application in the Firepower device, you can delete the images of the existing application FTD
and vice versa. When you try to delete all the FTD images, at least one image deletion will be denied with an error message
