When I purchased in the USA hardware for my Cisco lab, I got also some older AIR-LAP1142N access points.
With a wireless controller (I got the AIR-CT2504 model) and in lightweight mode they work fine, but for a special setup I needed an access point running as standalone.
The special setup in this case is a small installation where an ASA5505 provides LAN and Internet access and the access point is connected to one of the ASA’s Power-over-Ethernet ports.
Note: The same process can used to convert the access point back from standalone to lightweight software image.
Therefore I had to convert it with a standalone version and I explain the process here. The process is quite simple and
I would like to break it down into the following steps:
Boot lightweight access point with console cable and laptop connected
During boot process, send BREAK signal in your terminal application
Set network parameters which are required for TFTP download
Initialize TFTP, Ethernet and Flash
Extract software image from TFTP server to Flash via tar
Set BOOT variable to new software image
Verify the variables
Reboot access point to make sure it comes up with new image
At minimum the following variables should be set: IP_ADDR, NETMASK and DEFAULT_ROUTER:
Then the subsystems can be initialized with the following commands:
In the next step the software image must be extracted from a TFTP server:
Then it’s time to set the BOOT variable to the new software image. In addition I prefer to verify the variables, which can be accomplished by the set command:
Time to boot the access point with it’s new software image and to verify it comes up:
