Boot procedure

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.

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."

If a valid application image is not available
