ZyNOS (ZyXEL Network Operating System, sometimes referred to as the “ras” file)
is the system firmware and has a “bin” filename extension.
You can store up to two images, or firmware files of the same device model, on
the Switch. Only one image is used at a time.
• Run the
boot image <1|2>
command to specify which image is updated when
firmware is loaded using the web configurator and to specify which image is
loaded when the Switch starts up.
• You can also use FTP commands to upload firmware to any image.
The Switch supports dual firmware images,
ras-0
and
ras-1
. You can switch from
one to the other by using the
boot image <index>
command, where
<index>
is 1
(ras-0) or 2 (ras-1). See the CLI Reference Guide for more information about
using commands. The system does not reboot after it switches from one image to
the other.
44.8.1.1 Example FTP Commands
ftp> put firmware.bin ras-0
This is a sample FTP session showing the transfer of the computer file
"firmware.bin" to the Switch.
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 Switch only recognizes
“config”, “ras-0”, and “ras-1”. Be sure you keep unaltered copies of both files for
later use.
Be sure to upload the correct model firmware as uploading the
wrong model firmware may damage your device.
