SUN T2000风扇疑问 求解答
Solaris10，T2000的机器。有两台T2000都是下述现象。最近几个月吧，偶尔会死机，必须手动去把它起起来。以前是看系统日志有风扇报错，但是一下报三个，也没多想，就换了3个风扇，结果换了之后还是会报错，偶尔死机。确定不是风扇本身的问题。
贴出有关口令输出(很详细，但是不会每个口令的全部输出，那样费你们的眼睛)：

这些口令应该差不多了吧，各位大大们给点参考意见呗，明明已经换过风扇了但是就是不行，而且不是一台是这种诡异的现象，有两台。去现场看灯都是绿的，top fan盖子打开看那三个风扇也是转的，感觉是风扇接口的可能性几乎为0啊，还有什么其他的原因吗。难道报SYS_FAN at FT0/FM2 has FAILED.的时候风扇真的停止运转了？这到底是为什么呢？？？求解惑。（还需要贴什么口令说话）
风扇在加电的时候报这个错是正常的。从你收集的信息来看，风扇和其他硬件都没有问题
可能是BUG，建议升级固件版本或者系统patch 实际情况是不管是否加电，在系统运行的时候他也一直报这个错。
bug的话最多也是系统层面的呗，怎么一个系统bug能导致硬件上的风扇停止运转呢，这套系统是由好几台t2000组成的，现在是其中两台报这样的东西，而这几台的系统都是同时做的，应该是一模一样的系统。这个难道还有一定的偶然性啊。:em14: 如果所有风扇都有问题,那就是风扇电源板出问题了,是给风扇供电的一块板子坏了,它上面有芯片的. 换了它就行了. 楼主，你是不是搞差了。但愿不是。
SYS_FAN是屁股后头的那个风扇。
你说TOP fan是前面可以打开顶盖看见的风扇。 回复wenmaming_cu：
你说的那个模块就是那三个风扇插的那个小板子吧（长条状），你说有可能是那个小玩意坏了对吧，如果实在没有办法的话我会试试的。
回复wait空白：
你可能对T2000这个机器不熟，那个日志报的是SYS_FAN at FT0/FM2 has FAILED，FT0这个就是那三个风扇，那三个top fan，也就是我随时能够打开盖子看的那三个风扇。话说T2000屁股后边还有专门的冷却风扇？可能我没怎么关注过吧。我以为只有电源风扇呢。 后背风扇是FT2 回复 4# wenmaming_cu

很有可能是风扇电源板故障，我遇到过这种情况！
