Don't know too much about these, but if they are like the other LAP's then take a look at this documentation. Look for this:

Hi,


Even I have not dealt with this AP earlier. but looks like the Lightweight AP can not be converted to Autonomous afer doing a search on cisco.com.


Although there is no document which explicitely states this but this is what release notes states -


Converting an Autonomous AP521 Using the CCA -

When an autonomous AP521 access point is converted to controller-mode operation using the CCA, the access point properties screen continues to indicate that the access point is an AIR-AP521G-A-K9 after the conversion. This is in agreement with the product label on the access point. However, the CCA displays a small triangle icon next to the converted access point to indicate that the access point is now operating as a controller-mode access point.

--------------------------------------------------------------------------------

Note The CCA conversion process is one-way. Once the conversion takes place, you cannot restore the access point to autonmous operation.

Another link which talks about the conversion of Autonomous to Lightweight with the same restriction. It does not talks about LWAP to Auto conversion -

I'm no expert with this model. Can the AP join the WLC? If so, I would like to ask if you can invoke the following CLI command on the WLC:


config ap tftp-downgrade


Hope this helps.

Thanks for your response.


I was able to get the conversion done as follows:


tftp with correct image name modified to "c521-k9w7-tar.default". tftp server ip 10.0.0.2/27


repower the 521 holding the mode button until LED's go red (30 seconds). AP will broadcast for tftp service and load the image if it's name as above - make sure you dont have firewill services up!
