180 Chapter 15 Firmware and configuration file maintenance
NN47923-501
If your (T)FTP client does not allow you to have a destination filename different
than the source, you must rename the firmware and config file names as the
Business Secure Router only recognizes rom-0 and ras. Be sure you keep
unaltered copies of both files for later use.
Table 41 is a summary. Note that the internal filename refers to the filename on
the Business Secure Router and the external filename refers to the filename not on
the Business Secure Router, that is, on your computer, local network or FTP site
and so the name (but not the extension) can vary. After uploading new firmware,
see the 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.
Backup configuration
Using Option 5 from Menu 24 – System Maintenance, you can back up the
current Business Secure Router configuration to your computer. Backup is highly
recommended once your Business Secure Router is functioning properly. FTP is
the preferred method for backing up your current configuration to your computer
