Working with Software Images
Note To avoid an unsuccessful download, use the archive download-sw /safe command, which downloads
the image first and does not delete the current running version until the download succeeds.
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.
Note The procedure to downgrade an access point IOS is the same procedure for performing an IOS upgrade.
To downgrade an access point IOS, enter archive download-sw /overwrite /reload
tftp:[[//location]/directory]/image-name. The /overwrite parameter erases the current IOS image, and
the new downgraded version of IOS is loaded onto the access point. The /reload option reloads the
system after downloading the image unless the configuration has been changed and not saved.
Command Purpose
Step1 . Copy the image to the appropriate TFTP directory on the
workstation. Make sure the TFTP server is properly configured; see
the “Preparing to Download or Upload an Image File by Using
TFTP” section on page 20-20
Step2 Log into the access point through a Telnet session.
Step3 archive download-sw /overwrite /reload
tftp:[[//location]/directory]/image-name
Download the image file from the TFTP server to the access point,
and overwrite the current image.
•The /overwrite option overwrites the software image in Flash
with the downloaded image.
•The /reload option reloads the system after downloading the
image unless the configuration has been changed and not
saved.
•For //location, specify the IP address of the TFTP server.
•For /directory/image-name, specify the directory (optional)
and the image to download. Directory and image names are
case sensitive.
Step4 archive download-sw /leave-old-sw /reload
tftp:[[//location]/directory]/image-name
Download the image file from the TFTP server to the access point,
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
saved.
•For //location, specify the IP address of the TFTP server.
•For /directory/image-name, specify the directory (optional)
and the image to download. Directory and image names are
case sensitive.
