一、本次准备升级的设备型号 AIR-CAP16021-C-K9
二、 设置好电脑的IP地址以及准备好TFTP:将电脑IP设置成10.0.0.2/8,TFTP服务器使用的是solarwinds 10.9.1.33。
三、连接Console线,查看Console线的端口
四、使用设置串口参数如下
五、下载1602I的胖AP的IOS文件,网址:http://down.51cto.com/data/1897579
我的AP使用的IOS是在51CTO下载,其他型号的AP请下载对应的IOS文件
六、修改镜像文件的后缀为Default,并放到TFTP根目录下(关键步骤)
镜像文件的名称一定是这个:ap1g2-k9w7-tar.default ,如果不是这个文件名,会报错如下:
%Error opening tftp://255.255.255.255/ap1g2-k9w7-tar.default (no such file or directory)ap:
IP地址一定需要设置在10.0.0.0/8的这个网段,因为默认AP升级时使用的IP地址是10.0.0.1
七、在断电情况下按住Reset键,插入电源,按住Reset约20秒后,出现如下提示后,可以松开了,接着,AP会自动进行升级

九、进入系统
ap> en
输入密码Cisco
十、接下来就可以进行配置了,我们可以在CLI下面配置好AP的管理地址,然后开启HTTP管理。
十一、 配置过程 (略)
十二、备份配置文件 copy flash:/config.txt tftp://192.168.58.158 备份完成,妥妥的。
