Working with Software Images
The download algorithm verifies that the image is appropriate for the switch model and that enough 
DRAM is present, or it aborts the process and reports an error. If you specify the /overwrite option, the 
download algorithm removes the existing image on the flash device, whether or not it is the same as the 
new one, downloads the new image, and then reloads the software.
Note
If the flash device has sufficient space to hold two images and you want to overwrite one of these images 
with the same version, you must specify the /overwrite option.
If you specify the /leave-old-sw, the existing files are not removed. If there is not enough space to install 
the new image and keep the running image, the download process stops, and an error message is 
displayed.
The algorithm installs the downloaded image onto the system board flash device (flash:). The image is 
placed into a new directory named with the software version string, and the BOOT environment variable 
is updated to point to the newly installed image.
If you kept the old image during the download process (you specified the /leave-old-sw keyword), you 
can remove it by entering the delete /force /recursive filesystem:/file-url privileged EXEC command. 
For filesystem, use flash: for the system board flash device. For file-url, enter the directory name of the 
old software image. All the files in the directory and the directory are removed.
Caution
For the download and upload algorithms to operate properly, do not rename image names.
Uploading an Image File By Using FTP
You can upload an image from the switch to an FTP server. You can later download this image to the 
same switch or to another switch of the same type.
Use the upload feature only if the web management pages associated with the embedded device manager 
have been installed with the existing image.
Step 8
archive download-sw /leave-old-sw /reload 
ftp:
[[//username[:password]@location]/directory]
/image-name.tar
Download the image file from the FTP server to the switch, 
and keep the current image.
  •
The /leave-old-sw option keeps the old software version 
after a download.
  •
The /reload option reloads the system after downloading 
the image unless the configuration has been changed and 
not been saved.
  •
For //username[:password], specify the username and 
password. These must be associated with an account on 
the FTP server. For more information, see the 
.
  •
For @location, specify the IP address of the FTP server.
  •
For directory/image-name.tar, specify the directory 
(optional) and the image to download. Directory and 
image names are case sensitive.
