Chapter 29 Firmware and Configuration File Maintenance
The following table is a summary. Please note that the internal filename refers to the filename 
on the ZyXEL Device and the external filename refers to the filename not on the ZyXEL 
Device, that is, on your computer, 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. 
29.2  Backup Configuration
Option 5 from Menu 24 – System Maintenance allows you to backup the current ZyXEL 
Device configuration to your computer. Backup is highly recommended once your ZyXEL 
Device 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 ZyXEL Device to the computer, while upload means from your 
computer to the ZyXEL Device.
