HP RX8620下电无法启动诊断修复实例

背景：rx8620设备下电后无法启动

            服务器有一个CELL板，三个BPS(最小配置）

 

 

现象：rx8620电源正常，MP-》PE选项加电后仍然无法启动，前面板PWR灯灭

基础扫盲：

1.针对rx8620机器故障的诊断可以在mp卡（控制台）里面，结合各选项来分析故障点

2.介绍几个有用的选项，VFP(虚拟面板,可以查看机器的状态），CM->PS(查看各部件的加电状态），SL(查看事件日志），各部件的状态指示灯（根据不同的状态有不同的含义。

 

下面根据这次真实case情况具体说明

1.电缆A0,A1插入机器后插口，测电压没问题。

2.查看前面板standby pwr灯亮，说明3.3v电源已经加上了h

3.在MP卡CM选项下执行PE->T加电，机器没有加电的反应

4.借助查看事件日志SL,SEL,FPL,没有相关日志记录

5.下面看看相关操作的步骤和结果

请注意以上红色字体，PCI电源都正常，但是CELL0是无法加电的，再次对电源进行分析仍然没问题存在。

 

以上情况，只有一个CELL0存在，无法进行交叉测试，如果有多个备件，工程师可以考虑交叉测试，确定故障备件，然后进行更换。

 

最后确定故障备件为CELL板。

 

也许有的工程师会问，为什么不怀疑CPU或者内存呢？、

这里说下我的思路：因为这里，CELL是加不上电的，即使可能是还有别的部件损坏，那么我们通常先把最有可能的换掉，再来考虑其他故障问题。

 

 

最后解决：更换CELL板，问题解决。
