客户现场反馈,在为型号为WA4320-ACN-E的AP上传R1509P01胖版本进升级时,发现会提示加载失败导致无法成功升级,报错如下:

上传软件版本失败,首先查看该版本与AP型号的适配性,发现适配性正常。接着查看AP内是否有充足的内存空间可以存放软件版本,在Boot页面下进入文件控制目录下,展示所有文件,发现AP内并无文件存在,内存空间首先确认充足:

其次,查看现场操作是否准确,通过如下操作记录发现以太网参数设置无误,软件版本名称设置正确,使用的是FTP协议上传:

通过跟现场沟通了解到,现场多台同型号AP上传版本正常,可以确定软件版本下载正确,并不是版本下载错误导致。
该型号AP已经可以通过“Ctrl+Y”切换设备模式,键入 “Ctrl+Y”后查看AP模式,发现AP已经切换为了胖模式:
Please select the new mode
Current mode is Fat
============================================================================
|NO. Mode |
|1 Fat Mode |
|2 Fit Mode |
|0 Exit |
============================================================================
Enter your choice(0-2):1
Current mode is Fat!
上传版本时提示Loading...Failed!,多是由于FTP服务器和AP之间通信异常导致,但是查看现场的AP端口是正常UP的,且交换机侧可以正常学习到AP的MAC地址,于是让现场更换PC及连接线缆进行测试,现场在更换PC和线缆后发现有相同的报错。于是让现场再次使用TFTP协议进行上传测试,但是现场工程师在测试反应使用TFTP协议仍有该报错提示,且现场其他同型号AP用同样的PC和线缆是可以上传成功的。
经过多次测试,可以基本断定故障与终端和线缆无关,怀疑是AP的flash异常或损坏导致,让现场在AP Boot页面下使用“Ctrl+F”格式化flash后重新导入版本测试,现场在格式化flash之后重新操作上传软件版本,发现可以成功上传并升级。
AP在手动上传软件版本进行升级时,若升级操作无误,当多次进行FTP/TFTP服务器及中间线路的替换测试后,判断出是AP自身的问题导致时,建议在Boot页面下键入Ctrl+F格式化flash后重新进行软件版本升级操作。
