2.5.2. Restore: Backup configuration or change device firmware
The Restore function returns the BACnet Gateway to an earlier state without losing data. This is
useful if it the unit is not operating correctly because of a configuration change or a problem with
an application. It is also useful for disaster recovery if the unit fails completely.
By restoring the BACnet Gateway to an earlier state (a version before it began to display
problems), it may be possible to resolve the problems caused by a serious system issue or data
loss. In addition, you can use the Restore function to configure another unit before you fit it to an
existing system, thus reducing the repeat engineering time.
This feature is also used to apply firmware update files as necessary.
To restore a backup file:
1.
Press , and then select Restore to launch a browse
dialog box.
2.
Locate and select the required backup or firmware
update file, and then press Open.
This will upload the selected file and extract the
information from the backup or update file.
If restoring a backup file, the existing configuration will be overwritten.
If restoring a firmware update file, the unit firmware will be overwritten, and the
configuration files will remain unaffected.
Tip: The device beeps steadily while the backup or update files are being loaded. A fanfare
indicates that the process is complete, and the device restarts automatically.
The ‘Login’ page will appear when the IP connection has been re-established. This may
take several minutes and may require a Refresh of the browser.
To confirm that updates have been successfully applied, press ‘Show version info’
button on the ‘Home’ page.

(see the
Installation Guide). You must type them before you can access the configuration of the
device. After the device has been installed, change the default password to prevent unauthorised
access.
