大家好，来来为大家解答以下问题，dram黄灯如何处理很多人还不知道，现在让我们一起来看看吧！

组网及说明

本案例方法仅适用如下型号设备中存在console口的云AP

WAP611H、WAP611H-U、WAP811H、WAP622H、WAP622H-U、WAP622、WAP622-U、WAP822、WAP822H、WAP632H、 WAP812、WAP212H。

云AP黄灯常亮，reset恢复出厂设置之后依旧黄灯常亮，没有默认的wifi信号放出 ，这都是云AP丢失版本的表现。

如果发生版本丢失，当云AP存在console口时，我们可以进入bootware菜单手动更新版本。请注意仅当版本丢失时方可尝试串口进入bootware修复，操作存在风险请谨慎执行。云AP日常的维护和配置均在web，不可进入bootware。云AP正常启动后串口锁定，串口无打印信息。

配置步骤

1、波特率为57600，如果设置为其他波特率进入bootware菜单则会体现为乱码。提前搭建好TFTP服务器。

设备重启
