About Software Images

Each switch is shipped with a Cisco MDS SAN-OS operating system for Cisco MDS 9000 Family
switches. The SAN-OS consists of two images, the kickstart image and the system image. To upgrade
the switch to a new image, you must specify the variables which direct the switch to the images.

The images and variables are important factors in any install procedure. You must specify the variable
and the image to upgrade your switch. Both images are not always required for each install.
Unless explicitly stated, the software install procedures in this section apply to any switch in the Cisco
MDS 9000 Family.
