Appendix B Upgrading software

This section describes how to upgrade system software while the router is operating
normally or when the router cannot correctly start up.

System software file types

System software images are in .bin format (for example, main.bin) and run at startup. You
can set a system software image as a main, backup, or secure image.
At startup, the router always attempts to boot first with the main system software image. If
the attempt fails, for example, because the image file is corrupted, the router tries to boot
with the backup system software image. If the attempt still fails, the router tries to boot with
the secure system software image. If all attempts fail, the router displays a failure message.
