VNX5100双控启动都报Fan-Pack Failure导致存储无法正常启动

​大家好，最近遇到一个比较奇怪的故障，各位兄弟如有好的建议，感谢提供。具体信息如下：​

​1、有一台VNX5100，机房掉电导致存储掉电，重新加电后，发现存储启动了一会后即无任何反应，前面板硬盘灯不亮，后面电源和电池指示灯都是正常常绿。​

​2、通过串口线收集启动信息，发现​​A控制器和B控制器都提示Fan-Pack Failure​​，然后启动步骤都是停在int13 - EXTENDED READ (4200)，如下：​

​3、开始以为是风扇问题导致的，所以申请了电源备件进行更换，结果A和B控制器更换了电源模块后，串口输出跟上面的一模一样。现在无法判断是哪里出了问题。望各位兄弟能指点。谢谢！​
