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 P1600 internal filenames are ‘ras-m’ (main block) and ‘ras-b’ (backup block).

15.4.1 Dual Firmware Block Structure

The Prestige 1600 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.

15.4.2 Upload Prestige Firmware using FTP
