求：H3C-WAP712C AP的胖瘦切换失败解决方法

B.5.2 通过以太网口使用TFTP/FTP协议进行软件升级

1. 配置以太网口参数

在通过以太网口升级应用程序前，需要对AP的以太网口进行配置，请按如下进行配置：

在BootWare主菜单中键入<3>，进入以太网子菜单，然后键入<5>进入以太网口配置菜单：

============================<ETHERNET PARAMETER SET>======================

|Note:       "." = Clear field.                                          |

|            "-" = Go to previous field.                                 |

|          Ctrl+D = Quit.                                                |

==========================================================================

Protocol (FTP or TFTP) :tftp

Load File Name         :wa4300s_fat.bin

Target File Name       :wa4300s_fat.bin

Server IP Address      :192.168.0.1

Local IP Address       :192.168.0.50

Gateway IP Address     :

FTP User Name          :

FTP User Password      :

表9 以太网参数设置说明

2. 升级应用程序

以上配置均完成后，在BootWare主菜单下键入<3>进入以太网子菜单。然后键入<2>，系统开始升级主应用程序：

Loading......................................................................................................................................................................................................Done!

10788864 bytes downloaded!

Updating File flash:/wa4300s_fat.bin...................................................

.............................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................................Done!

升级完成后键入<0>，返回BootWare主菜单，然后键入<1>，启动系统。

FAT AP启动后可以使用display version命令查看FAT AP的版本，确认已经升级成功。

B.5.3 通过Console口使用XModem协议进行软件升级

1. 修改串口参数

通过Console口升级启动文件，在BootWare主菜单下键入<2>进入到串口子菜单，然后键入<5>系统会提示修改串口波特率：

=================================<BAUDRATE SET>===========================

|Note:"*"indicates the current baudrate                                  |

|     Change The HyperTerminal"s Baudrate Accordingly                    |

|---------------------------<Baudrate Avaliable>-------------------------

|<1> 9600(Default)*                                                      |

|<2> 19200                                                               |

|<3> 38400                                                               |

|<4> 57600                                                               |

|<5> 115200                                                              |

|<0> Exit                                                                |

==========================================================================

Enter your choice(0-5):

选择合适的下载速率，以115200bps为例：键入<5>，将提示如下信息：

Baudrate has been changed to 115200 bps.

Please change the terminal"s baudrate to 115200 bps, press ENTER when ready.

因为AP的串口波特率已经修改为115200bps，而终端的波特率还为9600bps，双方是无法通信的。所以根据上面提示，改变配置终端设置的波特率，使其与所选的下载波特率一致。

在终端上做如下操作：

图11 断开终端连接

点击[文件/属性]。在属性栏点击<配置(F)…>按钮，修改波特率为115200：

图12 修改波特率

点击[呼叫/呼叫]，重新连接：

图13 重新呼叫连接

然后按<Enter>键即可显示当前设置的波特率。

The current baudrate is 115200 bps

===============================<BAUDRATE SET>=============================

|Note:"*"indicates the current baudrate                                  |

|     Change The HyperTerminal"s Baudrate Accordingly                    |

|---------------------------<Baudrate Avaliable>-------------------------|

|<1> 9600(Default)*                                                      |

|<2> 19200                                                               |

|<3> 38400                                                               |

|<4> 57600                                                               |

|<5> 115200                                                              |

|<0> Exit                                                                |

==========================================================================

Enter your choice(0-5):

2. 升级应用程序

键入<0>返回串口子菜单：

===========================<Enter Serial SubMenu>===========================   

|Note:the operating device is flash                                        |   

|<1> Download Application Program To SDRAM And Run                         |   

|<2> Update Main Application File                                          |   

|<3> Modify Serial Interface Parameter                                     |   

|<0> Exit To Main Menu                                                     |   

============================================================================

Enter your choice(0-3):

在串口子菜单下键入<2>，系统提示：

Please Start To Transfer File, Press <Ctrl+C> To Exit.

Waiting ...CCCCCCCCCCCCCCCCCCCCCCCCCCCCCCC

从终端窗口选择［传送/发送文件］，弹出如下图所示的对话框：

图14 发送文件对话框

点击<浏览>按扭，选择需要下载的应用程序文件，并将协议设置为XModem，然后点击<发送>按钮，系统弹出如下界面：

图15 正在发送文件界面

下载完成后，终端界面出现如下信息，表明下载并升级成功：

Download successfully!

10788864 bytes downloaded!

Input the File Name:wa4300s_fat.bin

Updating File flash:/wa4300s_fat.bin..............................................

.....................................................Done!

将配置终端的波特率从115200bps修改为9600bps，重新启动AP。

FAT AP重启后可以使用display version命令查看FAT AP的版本，确认已经升级成功。
