local network or FTP site and so the name (but not the extension) may vary. After uploading new firmware,
see the ZyNOS F/W Version field in Menu 24.2.1 - System Maintenance - Information to confirm that
you have uploaded the correct firmware version. The AT command is the command you enter after you
press “y” when prompted in the SMT menu to go into debug mode.

22.2 Backup Configuration
The ZyWALL displays different messages explaining different ways to backup,
restore and upload files in menus 24.5, 24.6, 24. 7.1 and 24.7.2 depending on
whether you use the console port or Telnet.
Option 5 from Menu 24 - System Maintenance allows you to backup the current ZyWALL configuration
to your computer. Backup is highly recommended once your ZyWALL is functioning properly. FTP is the
preferred method for backing up your current configuration to your computer since it is faster. You can also
perform backup and restore using menu 24 through the console port. Any serial communications program
should work fine; however, you must use Xmodem protocol to perform the download/upload and you don’t
have to rename the files.
Please note that terms “download” and “upload” are relative to the computer. Download means to transfer
from the ZyWALL to the computer, while upload means from your computer to the ZyWALL.
