13.5 Backup Configuration
Selecting option 5 from Menu 24 - System Maintenance will allow you to backup your current
Prestige configuration onto disk. Backup is highly recommended once your Prestige
configuration is functioning.
You need to download the configuration onto disk. The procedure for downloading varies
depending on the type of software used to access the Prestige, but you must use the XMODEM
protocol to perform the download.
13.6 Restore Configuration
Selecting option 6 from Menu 24 - System Maintenance will restore backup configuration from
disk to the Prestige. You need to upload a backup file to the Prestige. The procedure for
uploading varies depending on the type of software used to access the Prestige, but you must use
the XMODEM protocol to restore the configuration.
Keep in mind that the configuration data are stored on flash ROM in the Prestige, so even if
power failure were to occur, your configuration is safe.
13.7 Software Update
Software updates are only possible through the RS-232 cable connection. You cannot use
telnet to update the software version of your Prestige. Note that this function will delete the
old software before installing the new software. Do not attempt to utilize this menu unless you
have the new software version. There are two different software updates: RAS code and ROM
File, as shown in Menu 24.7 (Figure 13-10).
