由FAT刷成FIT
步骤：
1、在AC上手工注册AP。
#wlan ap test model WA2620i-AGN
serial-id 219801A0CNC12B004476
radio 1
radio 2
channel 6
service-template 10
radio enable
2、保证AP和AC可以互通。二层即插即用，三层须保证AP管理地址段能和AC互通。
3、FAT AP上使用命令：
<H3C> ap-mode fit 此命令不可不全，只能手工输入！
使能此命令后AP会重启，重启过程中会格式化文件系统，重新从AC上下载软件版本。
启动后会提示从DHCP获取地址，获取成功后会显示：
DHCP server's IP address is 192.168.0.253
Client's assigned address is 192.168.0.2
DNS domain name got from DHCP server is
DNS server's IP address is 202.102.224.68
Default Gateway's IP address is 192.168.0.253
This client's subnet mask is 255.255.255.0
获取地址后DHCP状态变化：
The length of option 43 is: 9
Change State : Idle to Broadcast Discovery\\DHCP状态显示
Change State : Broadcast Discovery to Unicast Discovery\\广播转单播
Use Option 43:
Getting AC's IP Address 10.1.32.101
Change State : Unicast discovery to Sulking\\与AC连接失败
Change State : Idle to Broadcast Discovery
Change State : Broadcast Discovery to Unicast Discovery
The system will reboot\\两次连接失败后自动重启
AP与AC成功连接状态变化：
Use Option 43:
Getting AC's IP Address 10.1.32.101
Change State : Unicast Discovery to Join\\连接成功
Change State : Join to JoinAck
Change State : JoinCfm to Image Download..........................\\下载文件
[State : ImageLoad] Image download successful
[State : Idle] Reset request, rebooting the AP
Rebooting......
重启成功之后便是FIT模式。
操作过程中不可断电！
FIT刷成FAT
步骤：
1、将AP与FTP/TFTP 服务器连接，将wa2600a_fat.bin文件放在目录下（官网或AC上下载），并将服务器地址改为192.168.0.1/24；如果使用FTP服务器则需要新建用户：admin 密码：password
2、通过Console口进入AP命令行模式
3、FIT AP上使用命令
<H3C> ap-mode fat此命令不可不全，只能手工输入！
Change working mode will reboot system, do you want to continue? [Y/N]:\\默认Y
Change working mode to FAT (please ensure FAT app is present)? [Y/N]:
4、重启过程中在出现
Press Ctrl+B to enter extend boot menu...
键入<Ctrl+B>，系统提示：
BootWare password: Not required. Please press Enter to continue.
按下<Enter>键后，系统进入BootWare主菜单：
|<1> Boot System
|<2> Enter Serial SubMenu
|<3> Enter Ethernet SubMenu
|<4> File Control
|<5> Restore to Factory Default Configuration
|<6> Skip Current System Configuration
|<7> BootWare Operation Menu
|<8> Clear Super Password
|<9> Storage Device Operation
|<0> Reboot
选择<3>
<1> Download Application Program To SDRAM And Run
|<2> Update Main Application File
|<3> Update Backup Application File
|<4> Update Secure Application File
|<5> Modify Ethernet Parameter
|<0> Exit To Main Menu
选择<5>
出现以下提示：
Protocol (FTP or TFTP) : ftp\\可选择FTP或者TFTP
Load File Name : wa2600a_fat.bin
Target File Name : wa2600a_fat.bin
Server IP Address : 192.168.0.1
Local IP Address : 192.168.0.50
Gateway IP Address : 0.0.0.0
FTP User Name : admin
FTP User Password : password
Loading...
一直回车即可。
重启成功后便是FAT模式。
