Software Upgrading
Files
To upgrade the software on SecBlade cards, you need to upgrade and maintain the following three
categories of files:
l BootWare program file
l Application files
l Configuration files
BootWare program file
The BootWare program file on a SecBlade card is used for booting application files and is saved on
the Flash of the SecBlade card.
The entire BootWare program file contains a basic segment and an extended segment.
l The basic segment is used for the basic initialization of the SecBlade card. After the basic
initialization, the network interfaces and the CF card are still unavailable.
l After the SecBlade card runs the extended segment, the network interfaces and the CF card are
available. The extended segment provides diversified human-computer interaction (HCI)
functions to upgrade the applications and the boot system.
l After the basic segment is booted, the extended segment can be upgraded on the menu of the
basic segment.
Application files
Currently, the application files on a SecBlade card usually refer to the boot files. A boot file is an
application file used to boot the SecBlade card. By default, a SecBlade card defines three application
files for boot.
l Main application file (main file for short): The default name is main.bin and the file type is M. It is
the default application file used for the SecBlade card boot.
l Backup application file (backup file for short): The default file name is backup.bin and the file type
is B. When booting with the main application file fails, the SecBlade card uses the backup
application file to boot.
l Secure application file (secure file for short): The file name is secure.bin and the file type is S.
When booting with the main and backup application files fails, the SecBlade card uses the secure
application file to boot. When booting with the secure application file fails, boot failure will be
prompted.
These three types of files are stored on the CF card for all SecBlade cards except the SSL VPN cards.
For an SSL VPN card, the files are stored on the flash memory by default.
If you have loaded the three application files into the CF card, the SecBlade card will boot using these
three files in sequence. To change the sequence or a file type, refer to “Maintaining Files” on page 38.
Note that:
l The application files for booting the SecBlade card can be type M, B, and S, but not type N/A
(type other than M, B, or S).
