The names ras-0 and ras-1 are internal and not visible through FTP. You see “ras” when you type
"ls" at the FTP prompt. The IES updates the backup (non-active) image when you use FTP to upload
firmware to the IES. For example if the active (loaded) image is ras-0 and you use the FTP
put
command, the IES updates ras-1. At the next start up the IES loads ras-1 as the boot image and
keeps ras-0 as a backup. This ensures that the IES always has a bootable image (the backup one).
• Run the
boot image <1|2>
command to restart the IES with the specified firmware image (1:
ras- 0, 2: ras-1).
• Use FTP commands to upload firmware to the non-active image.
11.7.1.1 Example FTP Commands
Make sure you have downloaded (and unzipped) the correct model firmware and version to your
computer before uploading to the device.
Be sure to upload the correct model firmware as uploading the wrong
model firmware may damage your device.
ftp> put firmware.bin ras
This is a sample FTP session showing the transfer of the computer file firmware.bin to the IES.
ftp> get config config.cfg
This is a sample FTP session saving the current configuration to a file called “config.cfg” on your
computer.
If your (T)FTP client does not allow you to have a destination filename different than the source,
you will need to rename them as the IES only recognizes “config” and “ras”. Be sure you keep
unaltered copies of all files for later use.

active image. Similarly,
put config.cfg config
transfers the configuration file on your computer
(config.cfg) to the IES and renames it to “config”. Likewise
