In this blog first, we will introduce FXOS and then study upgrading FXOS.

FXOS: Firepower Extensible Operating System

The Firepower Extensible Operating System (FXOS) is the operating system for the Firepower 4100 on the supervisor. The Firepower Chassis Manager is a GUI-based management feature right out of the box to manage Firepower FXOS. The Firepower Chassis Manager is used to configure hardware interface settings, smart licensing for the ASA (Adaptive Security Appliance) on the supervisor. We can create logical devices like FTD, ASA on Cisco Firepower.
