Backup and restore 159
Restoring the NETA-21
1. Go to Settings –> Backup and restore –> Restore.
The Restore file function restores a selected file. If restoring requires rebooting (full
system restore), you are prompted to reboot the system. If you choose to reboot the
NETA-21, the reboot view is shown. When the server goes back online, you are
redirected to the Login window and eventually back to the Restore tab.
To restore the files stored in the SD card, select the Select an existing file from the
memory card check box.
2. Click the Restore file button.
The following dialog box appears.
If you select Store Ethernet IP address settings to keep_ip.mod file on memory
card, the NETA-21 tries to keep any previously defined fixed IP address configuration
over a firmware restoration. The current network interface configurations are saved to
a file on the SD memory card. The freshly initiated (factory resetted) firmware should
be able to read the previous network interface configurations and take those into use,
if the restored firmware is 2.22 or later.
The keep_ip.mod and any existing restore.log or restore.n21 files should be removed
from the SD memory card root folder after a system has rebooted to optimize the boot-
up mode and to enable similar functionality in future.
