Information About Software Images
Cisco Nexus devices are shipped with the Cisco NX-OS software preinstalled on the switches. Before 
you upgrade or downgrade from an existing image, you should read through the information in this 
document to understand the guidelines, prerequisites, and procedures for upgrading the software. For 
updated information about the Cisco NX-OS software for the Cisco Nexus device, see the Release Notes 
for your platform. 
The Cisco NX-OS software consists of the kickstart image and the system image. The system image 
includes the software for the Cisco Nexus device and the Cisco Nexus Fabric Extenders (FEXs) that are 
connected to the switch. The images contain a major release identifier, a minor release identifier, and a 
maintenance release identifier. The images might also contain a rebuild identifier, which can be referred 
to as a support patch. The following figure shows the version identifiers that are used with a combination 
of platform-independent and platform-dependent schemes for the Cisco NX-OS software.
