问题描述：
我的WA4320设备原本在V7平台使用，现在准备放到V5上使用，按道理来说格式化后接上AC应该可以上线，但是现在接收不到AC下发的版本，看了下AC是支持这个AP型号的，搜了下其他相似的方法是把V5版本导入到AP，然后将AP的bootware也降到V5，这个降级有详细的操作方法吗

最佳答案
您好，参考以下案例
V7瘦AP切换为V5胖AP配置案例方法 - 知了社区 (h3c.com)
1.1 适用产品系列
本手册适用于如下产品：WA4320i-X、WA4320i-ACN、WA4320H-ACN、WA4320-ACN、WA2620i-AGN、 WA2610E、WA2620E、WA2620X等AP。
有一些场景下，之前注册过V7无线控制器的瘦AP，需要切换成胖AP使用，但是对应的胖
AP版本是V5平台的，那就涉及到本案例的内容。需要先降级bootrom，再做版本上传。
1.1.1 AP瘦切胖配置案例（Bootrom）
操作风险提示：AP瘦切胖有风险，操作不当或者意外断电会导致设备故障，操作需谨慎。命令行升级需在PC上搭建TFTP Server（推荐用户使用3CDaemon搭建TFTP服务器）
将软件版本下载到设备FLASH内，然后通过命令行加载Bootrom版本，再加载主机软件版本，加载时输入的文件名一定要一致，建议复制黏贴，然后升级过程中避免断电重启操作。
配置步骤
1. 从新华三的官网下载对应AP型号的胖版本
https://www.h3c.com/cn/d_201805/1083983_30005_40.htm
下载压缩包WA4300S-CMW520-R1509P01-FAT.zip ，解压生成bin文件，放到电脑桌面上,下载后，需修改文件名，以WA4320为例子，修改对应的启动文件名wa4300s_fat.bin，需要注意文件名称修改正确。
2. 电脑通过网线连接到ap的一个网口
电脑网卡设置为：192.168.0.1 255.255.255.0，如下例子打开TFTP服务器，把bin软件版本放到电脑桌面上，TFTP服务器目录指向电脑桌面，然后点击确定。
3. console口操作刷版本
console口登录方法参考《1.03 设备管理-Console登录方法》
在AP重启的时候按住不停地按Ctrl+B进入设备的bootroom菜单，以下标黑部分为设备自动打印部分。
