Working with Software Images
The download algorithm verifies that the image is appropriate for the access point 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.
If the Flash device has sufficient space to hold two images and you want to overwrite one of these images
Note
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 current running image, the download process stops, and an error message is
displayed.
The algorithm installs the downloaded image on the system board Flash device (flash:). The image is
placed into a new directory named with the software version string, and the system boot path 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 image. All the files in the directory and the directory are removed.
Uploading an Image File by Using TFTP
You can upload an image from the access point to a TFTP server. You can later download this image to
the access point or to another access point of the same type.
For the download and upload algorithms to operate properly, do not rename image directories.
Caution
Beginning in privileged EXEC mode, follow these steps to upload an image to a TFTP server:
Command
Step 1
Step 1
Step 2 archive upload-sw
tftp:[[//location]/directory]/image-name.tar
The archive upload-sw privileged EXEC command builds an image file on the server by uploading these
files in order: info, the IOS image, the HTML files, and info.ver. After these files are uploaded, the
upload algorithm creates the tar file format.

Purpose
Make sure the TFTP server is properly configured; see the
"Preparing to Download or Upload an Image File by Using TFTP"
section on page 19-20.
Log into the access point through a Telnet session.
Upload the currently running access point image to the TFTP
server.
For //location, specify the IP address of the TFTP server.
•
• For /directory/image-name.tar, specify the directory (optional)
and the name of the software image to be uploaded. Directory
and image names are case sensitive. The image-name.tar is the
name of the software image to be stored on the server.
