Patton electronic SmartNode 4110 Series manual System image handling task list

SmartWare Software Configuration Guide 5 • System image handling

Operating configurations cannot be executed from the persistent memory, so the configuration used for oper- ating the SmartNode is copied into the volatile memory of the SmartNode prior to normal operation. This procedure takes place after the system bootstrap, where the application image (i.e. SmartWare) is started and a configuration must be available. Shortly before SmartWare has completed all startup processes, the configura- tion startup-configis copied from nvram: in persistent memory to the running-configconfiguration in system: in volatile memory.

You can back up the running-configto nvram: or to a remote TFTP server with a user-defined name.

Note When returning to the factory-configby using the copy factory-config star- tup-configcommand, all user-specific configurations saved in nvram: remain even after reload.
