2. Remove the SD card from the linking device containing the desired configuration and insert
it into another one.
The firmware version must be the same or higher in the new linking device.
The new linking device must support the same network type as the first linking device.
3. Turn the new linking device on. The new linking device will automatically start up using the
configuration found on the SD card.
If the configuration was protected by authentication information, the same information
will be needed to alter the configuration in the new linking device.
G.5 SD Card Synchronization Failure
In the event of applying a configuration or restoring a configuration from a backup file, the SD
card synchronization can fail. There are many possible reasons for an SD card write failure:
• The SD card is write-protected.
• The configuration file on the SD card is write-protected.
• The SD card memory is full.
• The SD card file system is corrupt.
• The SD cad is damaged.
If the SD card write process fails, the reboot cycle of the linking device will halt. The GW LED will
indicate “invalid configuration” and the SD LED will indicate “failure”.
To eliminate the problem, follow the steps below:
1. Turn the linking device off.
2. Remove the SD card. Find the cause of the problem.
3. Insert an SD card.
This SD card must not contain a configuration file. If it does, the configuration on the SD card will
overwrite the configuration on the linking device.
4. Turn the linking device on. The linking device will run the configuration that was applied or
restored when the SD card write process failed.
5. Apply the configuration in the Management section to save the configuration to the SD card.
6. Now, the SD card is synchronized with the linking device. Both the SD card and the linking
device contain the latest applied configuration.
