Software Maintenance
Overview
Files Managed by the Access Controller
The WX5004 manages the following three types of files:
z
BootWare program file
z
Application file
z
Configuration file
BootWare Program File
The BootWare program file is used to boot the applications when the access controller is started up.
The complete BootWare program file consists of two segments: basic and extended.
z
Basic BootWare implements the basic system initialization.
z
Extended BootWare provides abundant human-computer interaction (HCI) functions. It is used for
interface initialization for upgrading applications and booting the system.
z
The full BootWare refers to the combination of the two segments. After the basic BootWare is
booted, you can load or upgrade the extended BootWare on the menu of the basic BootWare.
Do not power off or restart the access controller during BootWare upgrade process; otherwise, the
BootWare program may be damaged and the access controller may fail to operate normally.
Application Files
The WX5004 supports the Dual Image function. By default, three application files are defined for system
boot:
z
Main application file (main file)
z
Backup application file (backup file)
z
Secure application file (secure file)
These files are stored on the built-in CF card, with the extension
.bin
.
Typically, the default application file is written into the built-in CF card of an access controller before it is
delivered.
If you have loaded the three application files to the CF card, the system uses these three files to boot
the access controller in the sequence of main.bin, backup.bin, and secure.bin. For how to set the
application file types, refer to section “
