Boot procedure
During a normal boot procedure of a SmartNode, the bootstrap application checks for an application image in
the persistent memory and executes it. One of the last start-up tasks to finish in bringing up the entire system
is handling 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.

illustrates
the boot procedure.
