"on the switchport do a no power inline, then a power inline auto. that will cycle the power for you.

不明白什么意思，大家能否给与解释。

创建个vlan 999将AP和电脑放置在一个未使用vlan里面
接着mode键，加电
过了25-30秒，AP的状态LED变成红色（紫红色），
AP给自己分配IP地址10.0.0.1
然后，自动从TFTP服务器下载默认IOS文件
Tftp://255.255.255.255/xxx.default
server设置成10.0.0.0/24

感谢你的回复，但是很遗憾，依然不能起效；我正尝试看看是否有其他方法；

之前一直使用如下命令进行升级：
AP#debug capwap console cli
AP#debug capwap client no-reload
AP#config t
AP(confg)int fa 0
AP(confg-if)ip addr (same subnet as that of the laptop)
AP(confg-if)no shutdown
AP(confg-if)end
AP#archive download-sw /force-reload /overwrite tftp:///
查过资料后才发现，会因为文件过大导致传输失败的....T_T.....
还是直接按“MODE”健，来的方便......

AP#debug capwap client no-reload

除了mode键，也可以通过web升级，选择system software点击进去，选择下载的瘦IOS文件，点击upgrade system
胖AP转瘦遇到过文件过大的问题，瘦AP本身文件就很小，我占时没遇到过:lol

之前遇到过类似的问题，好像更换下思科推荐的TFTP服务器或者3CDaemon 就可以解决
