The following might occur at the switch startup:
1. The switch starts up with the main system software image.
2. The main system software image is faulty and the switch starts up with the backup system software
image.
3. Both the main and backup system software images are faulty and the switch picks a random
system software image and starts up with it.
4. If the switch still cannot start up with the random system software image, it decides that there is no
valid system software image and stops picking any system software image.
