Quidway AR 28 Series Routers Installation Manual
are available from Flash memory. If the router fails to boot with the secure boot file, it
prompts the boot failure.
The following table gives default names and types of boot files.
Table 6-1 Default names and types of the boot files
Main boot file
Backup boot file
Secure boot file
Note that:
The application images for system boot can be type M, B and S, but not type N/A.
You can store them in Flash memory, but only one for each. For example, if an
M+B file exists, it is impossible to have another M or B file. If you change the file
type of another file to B, the M+B file becomes a type M file.
You can modify the file name of an application image in Flash memory using the
command after it boots.
You cannot modify the file type of a type S application image file, but you can
modify the file type of type M/B and N/A application image files in the Boot ROM
menu or using commands after the application image boots.
Secure boot file is the last resort for system boot. You can download it in the Boot
ROM menu and must name it secure.bin. However, you cannot modify this file or
change the type of another file to S. If you change the name of the secure boot file
with the rename command after the system boots, the file is removed from Flash
memory. To use the secure boot file after that, you need to download it again.
The name (including the extension) assigned to a boot file is recommended to be
less than 16 characters.
