• Backup application file. The default name is backup.bin, and the file type is B. Upon failure of

loading the main application file, the system tries to load the backup file.

• Secure application file. The default name is secure.bin, and the file type is S. If the system fails to

load the backup application file, the secure application file is the last choice. If it again fails to load

the secure application file, the system will give a boot failure message.

Note that:

• Only the application files of the M, B, and S types can be used to boot the system, while an

application file of the N type (an application file other than the M, B, or S type) cannot.

• After the application program is loaded, you can rename the application files through the

command line interface (CLI) or change the types of the M, B and N application files through the

BootWare menu or the CLI. However, you cannot change the type of the S application file.

• As the S application file is the last choice for booting the system, you cannot change its type or

obtain it by changing the type of another type of application file. You can only download it using

the BootWare menu.

• Only one file of the same type (M, B, or S) can exist in the CF card or Flash. For example, if an

application file of type M+B exists in the CF card of LSRM1WCM2A1, another file of type M or B

cannot exist. If the type of another file is changed to B, the existing type M+B file changes to a file

of type M.

Configuration files

With a file extension of .cfg, configuration files store the configuration information of the access

controller module. Generally, an access controller module carries no configuration file with a .cfg

extension when delivered. When the access controller module starts, the default configuration is loaded.

If the access controller module starts again when the configuration file is deleted or lost, the default

configuration is also loaded.

CAUTION:

• The len

th of a confi

uration file name must not exceed 64 characters (includin

the drive name and the

string terminator). For example, if the drive name is cfa0:/, the maximum len

th of a file name is [ 64

– 1 – 4 ] = 59 characters.

• If the length of a file name exceeds 59 characters, error will occur in file operations on that file. It is

recommended to keep the file name within 16 characters.

• There is a limitation on the length of file name that can be displayed in the BootWare menu. If a file

name is shorter than 30 characters, all the characters of the file name can be displayed; if a file name

has or exceeds 30 characters, only the first 26 characters of the file name can be displayed, followed b

a tilde (~) and a serial number. The serial number identifies position in sequence of the file. For example,

if some files, file A, file B and file C, have a file name lon

er than 30 characters, the name of file A will

appear as the first 26 characters plus ~001, that of file B will appear as the first 26 characters plus ~002,

and that of file C will appear as the first 26 characters plus ~003.
