Working with Software Images
Deleting a Stored Configuration File
Caution You cannot restore a file after it has been deleted.
To delete a saved configuration from Flash memory, use the delete flash:filename privileged EXEC
command. Depending on the setting of the file prompt global configuration command, you might be
prompted for confirmation before you delete a file. By default, the access point prompts for confirmation
on destructive file operations. For more information about the file prompt command, refer to the Cisco
IOS Command Reference for Release 12.4.
Working with Software Images
This section describes how to archive (download and upload) software image files, which contain the
system software, Cisco IOS software, radio firmware, and the web management HTML files.
You download an access point image file from a TFTP, FTP, or RCP server to upgrade the access point
software. You upload an access point image file to a TFTP, FTP, or RCP server for backup purposes. You
can use this uploaded image for future downloads to the same access point or another of the same type.
The protocol you use depends on which type of server you are using. The FTP and RCP transport
mechanisms provide faster performance and more reliable delivery of data than TFTP. These
improvements are possible because FTP and RCP are built on and use the Transmission Control
Protocol/Internet Protocol (TCP/IP) stack, which is connection-oriented.

Note For a list of software images and supported upgrade paths, refer to the release notes for your access point.
Image Location on the Access Point
The Cisco IOS image is stored in a directory that shows the version number. A subdirectory contains the
HTML files needed for web management. The image is stored on the system board Flash memory
(flash:).
You can use the show version privileged EXEC command to see the software version that is currently
running on your access point. In the display, check the line that begins with
System image file is...
It shows the directory name in Flash memory where the image is stored.
You can also use the dir filesystem: privileged EXEC command to see the directory names of other
software images you might have stored in Flash memory.
