Although the 12 series AP has been eliminated, but like our company with no money for 10 years but still in use, fortunately it has the value of learning, or can be seen from the 12 series of APS some Cisco deployment of wireless ideas.
First spit trough a bit of the domestic often said fat, thin ap of this argument, because when using Thin/thick mode to Google, often do not search the results, so first to tidy up the fat and thin what is it?
Fat AP, to AIR-AP1242AG-C-K9 this 12 series AP, for example, after the factory, it is the default mode is the FAT AP, that is, with a complete GUI and cli,show version when the display of its software will see C1240 software (c1240-k9w7-m), show inventory will also see PID is AIR-AP1242AG-C-K9, this ap its big name is autonomous AccessPoint, Also become stand alone AP on Google.
Thin AP, or AIR-AP1242AG-C-K9 this 12 series AP as an example, the factory although the default is autonomous access point, but can be brushed into a thin AP, the big name of the thin AP lightweight Access Point, /c1> When this mode is painted, show version will see the K9W8, show inventory see the PID will become AIR-LAP1242AG-C-K9 (more than the default factory when a L, meaning lightweight). Lightweight mode requires WLC is often said in the domestic AC, foreign often said "wireless controller" support.
Spit slot version of the name, K9W7 is fat, k9w8 is thin, but these two versions of the name in addition to this place, other places do not see any expression it is lightweight or autonomous place.

The following is a way to change from autonomous to lightweight (i.e. from fat to thin):
Step 1,
Ap#lwapp IP? Use this command with IP, mask, gateway, gateway pointing to the laptop as Tftpserver
Step 2, use this image as the boot image, unzip, and restart
Use the following command
Ap#archive download-sw/over/create-space tftp://Notebook's Ip/c1240-rcvk9w8-tar.124-21a.ja2.tar
The above command in the/over represents override, in fact, you can also use/leave that is to keep an old iOS, the old iOS that is saved is Fat mode of iOS, the next time directly press the mode key can be restored to autonomous mode.
