SmartWare Software Configuration Guide 5 • System image handling
The bootloader ensures that basic operations, network access, and downloads are possible in case of interrupted
or corrupted application image downloads.
After downloading an application image (that is, new system software/software upgrade), the bootloader
ensures that basic operations, network access, and downloads are possible in case of interrupted or corrupted
application image downloads. After downloading an application image, the bootstrap will only switch to the
newly loaded application image if it is valid. If it is not valid, the bootstrap still uses the application image
which existed prior to doing a software upgrade.
If the application image is valid, it is started and SmartWare is brought into operation module by module.
During this system initialization phase (when the message Press reset button to restore factory defaults... appears
on the console screen), the status of the reset button on the back panel of the SmartNode is checked. If the but-
ton has been pressed, the factory configuration is loaded into the volatile memory and is used to parameterize
the SmartWare (not available for SN4xxx). If the button has not been pressed, the startup configuration is
loaded into the volatile memory and is used to parameterize the SmartWare.
Factory configuration
SmartNodes are delivered with a factory configuration stored in the logical region nvram: of the memory. It is used
to initially parameterize the network and component settings of SmartWare, which makes sense at the very begin-
ning. Moreover, in case of SmartWare malfunction, you can reset to the initial state by reloading the factory con-
figuration. The factory configuration consists of the default settings for the IP networking subsystem.
Once the user-specific configuration is created and stored as startup configuration, the factory configuration is
no longer used but it remains in the persistent memory. It is possible to switch back to the factory configura-
tion at any time during the operation of a SmartNode.
Default Startup Configuration
The SmartNodes delivered from the factory contain both a factory configuration and a default startup configu-
ration. While the factory configuration contains only basic IP connectivity settings, the default startup config-
uration includes settings for most SmartWare functions. Note that if you press and hold the system button
(Reset) for 5 seconds the factory configuration is copied onto the startup configuration (overwrite). The default
startup config is then lost.
IP Addresses in the Factory Configuration
The factory configuration contains the following IP interfaces and address configurations bound by the Ether-
net ports 0/0 and 0/1:
interface eth0
ipaddress dhcp
mtu 1500
interface eth1
ipaddress 192.168.1.1 255.255.255.0
mtu 1500
Avoid downloading any system image if you do not completely
understand what you have to do!
