Boot procedure

SmartWare Software Configuration Guide 

During a normal boot procedure of a SmartNode, the bootstrap application checks for an application image in 
the persistent memory of the logical region nvram:. The application image is then executed, i.e. the SmartWare 
is started module by module. One of the last start-up tasks to finish in bringing up the entire system is han-
dling the operating configuration. The configuration startup-config is copied from the logical region nvram: in 
nonvolatile memory to the logical region running-config in the volatile memory. The SmartWare now uses the 
running-config to set up the operating configuration of the SmartNode. 

 illustrates the boot procedure.

Figure 9. Boot procedure

There are two situations during bootstrap when the bootloader takes control:

•

“If the user has pressed the system button, it launches the bootloader, the bootstrap application checks the 
status of the Reset button (not available for SN4xxx) on the back panel of the SmartNode.”

•
