When started normally, the devices try to use the available configurations in a set order:
- User-defined configuration (in the configuration memory)
- Customer-specific standard settings (in the first boot memory space)
- Factory settings (in firmware)
The customer-specific standard settings are taken automatically and in preference to the factory settings, assuming that the configuration memory is empty.
Special features of the rollout configuration
The rollout configuration is activated with the reset button. The reset button fulfills various functions depending upon how long the button is pressed:
- Less than 5 seconds:Boot (restart), whereby the user-defined configuration is loaded from the configuration memory. If the user-defined configuration is empty, then the customer-specific standard settings (first memory space) are loaded instead. The loading of the customer-specific standard settings is visible when all LEDs on the device light up briefly in red. Similarly, the factory settings are loaded if the first memory space is empty.
- Longer than 5 seconds until the first time that all device LEDs light up:Configuration reset (deletes the configuration memory) followed by a restart. In this case the customer-specific standard settings (first memory space) are loaded instead. The loading of the customer-specific standard settings is visible when all LEDs on the device light up briefly in red. The factory settings are loaded if the first memory space is empty.
- Longer than 15 seconds until the second time that all device LEDs light up: Activating the rollout configuration and deleting the user-defined configuration After restarting, the rollout configuration is started from memory space 2. The loading of the rollout configuration is visible when all LEDs on the device light up twice briefly in red. The factory settings are loaded if the second memory space is empty.
The rollout configuration is activated directly after restarting if the reset button is pressed for more than 15 seconds. The next time the device is restarted, the normal boot sequence applies again automatically, as listed above.
Examples
The following diagram illustrates which configuration is loaded by the different reset procedures, depending on the status of the device.
- Pressing the reset button for less than 5 seconds loads the user-defined configuration. If no user-defined configuration exists, the device returns to the customer-specific standard settings. If these are not available either, the factory settings are loaded.
- Pressing the reset button for longer than 15 seconds deletes the custom configuration and loads the rollout configuration. If no rollout configuration exists, the factory settings are loaded.
