● Configuration Mode  
Select the mode from the drop-down list. The following modes are possible:
– Automatic Save
Automatic backup mode. Approximately 1 minute after the last parameter change or 
when you restart the device, the configuration is automatically saved. In addition to this, 
the following message appears in the display area "Changes will be saved automatically 
in x seconds. Press 'Write Startup Config' to save immediately."
Note
Interrupting the save
Saving starts only after the timer in the message has elapsed. How long saving takes 
depends on the device.
During the save, the message "Saving configuration data in progress. Please do not 
switch off the device" is displayed.
● Do not switch off the device immediately after the timer has elapsed.
– Trial
Trial mode. In Trial mode, although changes are adopted, they are not saved in the 
configuration file (startup configuration). 
To save changes in the configuration file, use the "Write startup config" button. The 
"Write startup config" button is displayed when you set trial mode. In addition to this after 
every parameter change the following message is displayed in the display area: "Trial 
Mode Active – Press "Write Startup Config" button to make your settings persistent" as 
soon as there are unsaved modifications. This message can be seen on every WBM 
page until the changes made have either been saved or the device has been restarted.
