4.5.2 Image Management
The FXOS chassis uses two basic types of images:
• 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 FXOS 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.
WARNING! 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.
