Firmware

Ras

*.bin

This is the generic name for the ZyNOS
firmware on the Prestige.

Backup is highly recommended once your Prestige is functioning properly. FTP and TFTP are the preferred
methods for backing up your current configuration to your computer since FTP and TFTP are faster. Any
serial communications program should work fine; however, you must use Xmodem protocol to perform the
download/upload and you don’t have to rename the files (see section 5.1).

Please note that terms “download” and “upload” are relative to the computer. Download means to transfer
from the Prestige to the computer, while upload means from your computer to the Prestige.

Follow the instructions shown next.

Step 1.  Launch the FTP client on your computer.

Step 2.  Enter “open”, followed by a space and the IP address of your Prestige.

Step 3.  Press [ENTER] when prompted for a username.

Step 4.  Enter your password as requested (the default is 1234).

Step 5.  Enter “bin” to set transfer mode to binary.
