Upload Firmware
Option 7 from Menu 24 - System Maintenance takes you to Menu 24.7 - System Maintenance - Upload
Firmware which allows you to upgrade the firmware. You can upgrade the firmware either through FTP or TFTP
(preferred methods as they are faster) or through the RS-232 console port (if the network is down). The system
reboots automatically after the file transfer process is complete.
The Prestige P1400 internal filenames are 'ras-m' (main block) and 'ras-b' (backup block).

14.4.1 Dual Firmware Block Structure
The Prestige employs a "dual firmware block structure" where one block is called the "main block" and the other
block is called the "backup block". The benefits of this approach are:
You can save the current firmware into the backup block before you upload new firmware. If the new firmware has
problems, you may either revert to the old working firmware by using the "ATSW" command under Boot
Extension or selectively run the old firmware in the backup block by using the "ATGB" command under Boot
Extension.
If the firmware in the main block gets corrupted for some reason, the Prestige will try to boot from the backup
block automatically.
