2.0 Backup configuration
To backup the individual configuration files follow the process below.
2.1 Locate the files
Status > File Directory
4 files need to be saved from the router’s flash memory, these are config.da0 (the current config),
sregs.dat (the ASY port S registers), fw.txt (the firewall rules) & x3prof (pad profiles). Right click
each file and choose to save the file to your desktop, then move the files to a secure location such
as a backed up file server.
2.2 Restore configuration
In a disaster recovery situation, obtain your spare router and ensure the firmware is at the same
level as your previous router. Via the serial ASY 0 connection and your terminal emulation
software, configure a temporary IP address on Ethernet 0 in the same subnet as your PC to
facilitate an FTP connection. (Serial settings 115200, 8-none-1, no flow control)
Check serial comms: at
Set the IP address: eth 0 ipaddr
Set the Subnet mask: eth 0 mask
FTP the 4 files from your backup onto the router, the files in the example have been placed in
Open a command prompt: Start > Run > command
FTP to the configured IP address: ftp
Enter the username and password to login (u=username / p=password)
Change to binary mode: bin
Change the local directory: lcd c:\sarian_backup
Transfer the files: mput *
Logout: bye
Reboot the router, when it restarts the configuration is restored.
