Convert AP 1572E from lightweight to autonomous

[sobin peter]

Trying to convert 1572E from lightweight to autonomous but not working. Configured and IP in ethernet port and bvi interface.

APac3a.6744.a720#ping 10.1.1.1
Type escape sequence to abort.
Sending 5, 100-byte ICMP Echos to 10.1.1.1, timeout is 2 seconds:

% Unrecognized host or address, or protocol not running.

Please suggest any alternate convenient method to covert the outdoor AP 1572E to autonomous.

Did you upload the autonomous image to the AP? You can verify using show version and check whether image name contains k9w7. 

Alternatively you can follow the below forum which is really helpful and the method is still valid.

Just to add, there are a lot of posts on the same subject. Personally search the forum and internet and review some blogs. That is the easy way to get the step by step process.  
ideally, like what was mentioned, you need to get the autonomous image and upload that to the ap. Of course you need a support contract to download that.
