• Main—Main system software image to be used at the next startup. The main
system software image has higher priority than the backup system software
image at startup.

to start up the device when the main system software image is not available.

root directory for a successful
upgrade.
If the storage medium has been
partitioned, save the image file to
the root directory of the first

Installing hotfixes
Hotfixes (called "patches" in this document) repair software defects without requiring a system reboot.
Basic concepts
This section describes the basic patch concepts.
Patch, patch file, and patch package file
A patch fixes certain software defects.
A patch file contains one or more patches. After being loaded from the storage medium to the patch
memory area, each patch is assigned a unique number, which starts from 1. For example, if a patch file
has three patches, they are numbered 1, 2, and 3.
A patch package file contains patch files for multiple modules. It enables you to use one command to
bulk-fix bugs for multiple modules.
