    谢谢楼上的兄弟，上面的那张图我看到了，在右下角时有一个obp，但是，是固化在主板上的，无法移动，可我在sun手册中看到v440的硬件中有Boot PROM ，还有它的PN号，是525-1970   ，可我就是在主机上没有者到这个。

  今天早上，我一开v440，就无法加电，报电源正常，Boot PROM 没有反应

请问：有人遇见过这样的问题吗？

升OBP和ALOM,BUG

Bug ID: 6485416Synopsis: SC Alert "Open Boot not responding" is reported when system is powered on, after updating OBPCategory: firmwareSubcategory: obpState: 11-ClosedDescription: Error "SC Alert: Host Power-On Failed: System Power OK, Open Boot not responding" is outputed to SC when host system is powered on, after OBP 4.22.11 or 4.22.19 are applied.

Error does not exist before update from 4.18.10, and if you downgrade OBP 4.18.10 error is NOT reported.

    可现在的问题是，有问题的v440是环保的，其他的v440就都不是了，现在环保的机器加不了电，要是拿到其他的v440上，ALOM卡又无法和主板上的obp通讯上级呀！这该怎么办呀？

不知道你是不是遇到的这个bug，反正calcm遇到的和bug描述中的一样，都是2CPU的机器，你可以试试把CPU拔一个下来试试。
即便是这个bug，也不是每次都起不来的
