After the reboot, the AP will load the autonomous image. The default username and password are usually Cisco and Cisco (case-sensitive), or it may ask you to configure a new user. To verify the upgrade: ap# show version
The target keyword refers to a highly specific Cisco network image file: c1240-k9w7-tar.124-25d.JA2.tar . Network engineers use this exact software bundle to convert or upgrade legacy Cisco Aironet 1240 Series access points from lightweight mode to autonomous (standalone) mode.

The subsequent identifiers, Tar 124 25d, refer to the packaging and versioning of the Cisco IOS software. The ".tar" extension indicates a compressed archive that typically includes not just the binary executable but also the necessary HTML management files for the web-based GUI. The "124 25d" specifies the exact version—Cisco IOS 12.4(25d)—which was a landmark release for stability and security patching in the Aironet line. For a network technician, this version ensures compatibility with specific encryption standards like WPA2 and provides the command-line stability necessary for mission-critical infrastructure.
Do not unpack the .tar package on your computer. Ensure that your TFTP client software is explicitly set to Binary transfer mode instead of ASCII mode. Download a fresh copy of the archive file directly from an authorized Cisco software portal. 2. No Such File or Directory / Failed to Open Archive
