Cisco Access Point IOS images

There are three types of Cisco Access Point IOS available.

These are the:

• k9w7 – autonomous IOS
• k9w8 – full lightweight IOS (this is what is bundled in the WLC .aes image, and is factory installed on “mesh” APs)
• rcvk9w8 – lightweight recovery image – this is factory installed on lightweight APs, unless a “mesh” image is specified; it lacks radio firmware

i.e. you have the ” c1140-k9w8-tar.152-2.JB.tar ” it contains the code k9w8 so it is a Full Lightweight IOS.
