A warm start occurs when you hot-swap a module, press the Reset button, or issue
the
boot or reset command. The processor module boots without running
diagnostics. When you hot-swap a module, the DIAG LED on the front panel and
LED 8 on the FRE module daughterboard behind the RFI shield remain on,
indicating that diagnostics have not been run. (We recommend that you issue the
diags command when you hot-swap a board.)
When a processor module boots, it requests a copy of the router software image
currently in use. The first processor module to respond to the request forwards a
copy of the router software image from its memory. If none is in use, the processor
module uses the router software image stored on its own volume, if one is
available. The processor module then boots.
After it boots, the processor module requests a copy of the configuration currently
in use. The first processor module to respond to the request forwards a copy of the
configuration from its memory. If none is in use, the processor module uses the
default configuration file (config) stored on its own volume, if one is available.
The processor module then loads the configuration and initiates software services.
Booting
Use the boot command to boot the entire system.
Enter the following command to boot the entire system with the default software
image (for example, bn.exe) and default configuration file (config):
boot
Caution:
If you do not specify the router software image and configuration
file when entering the
boot command, the system boots from the default image
(for example, bn.exe) and configuration file (config). We recommend that you
have only one version of the config file on the router. You can comply with this
recommendation by assigning new names to alternative versions of the
configuration file. The processor modules can simultaneously load different
configurations if you have alternative versions of the config file and you enter
the
boot command without specifying the volume and configuration file with
which to boot.
