Appendix E Maintaining software
Files managed by the switch
The WX3024E consists of two virtual systems: access control engine and switching engine, for which two
independent file systems are employed to manage the following types of files:
• BootWare image file
• System software image files
• Configuration files
The access control engine manages the system software image files and both the access control engine
and switching engine store and manage their respective BootWare image file and configuration files.
BootWare image file
The BootWare image file is used to boot applications during the startup of the switch. A complete
BootWare image file includes a basic section and an extended section.
• The basic BootWare section is used to complete the primary initialization of the system.
• With rich human-computer interaction (HCI) functions, the extended BootWare section is used for
initializing the interfaces and upgrading the system software image files and the boot system.
• A complete BootWare image is the combination of the basic and extended BootWare sections.
After the basic BootWare section is started, you can download and upgrade the extended
BootWare through the menu of the basic BootWare section.
CAUTION:
Do not power off or restart the switch when upgrading the BootWare image file; otherwise, the BootWare
image may be damaged and the switch may fail to operate properly.
System software image files
The WX3024E supports the Dual Image function. By default, the system defines the following system
software image files for system boot:
• Main file
• Backup file
• Secure file
These system software image files are stored in the Flash memory, with the file name extension of .bin.
Typically, the default system software image files are written into the built-in Flash memory before switch
delivery.
If you have loaded all the three types of system software image files in the Flash memory, the system uses
these files to boot the switch in the sequence of main.bin, backup.bin, and secure.bin. For how to set the
type of a system software image file, see “ Maintaining the system software image files and configuration
files .”
