rc.powerfail问题

今天看到客户有台650报错，显示wall% rc.powerfail:2::WARNING!!! The system is now operating with a power problem.  This message will be walled every 12 hours. Remove this crontab entry after the  problem is resolved.

errpt中被存储的一个硬件错误占满了，看不到其他的错误，看电源状态，没什么异常，只是略微感觉有一个电源的风扇的风比另一个小一点。
看crontab中有如下相关内容：
0 00,12 * * * wall% rc.powerfail:2::WARNING!!! The system is now operating with a power problem.  This message will be walled every 12 hours. Remove this crontab entry after the  problem is resolved.

请问一下这个问题如何解决？
是否需要换电源？还是把crontab中的相关内容删掉就可以了？
谢谢各位指导，不胜感激

把crontan里的这些 rc.powerfail都删了。
从外部特征检查电源是否有问题，如果没问题就是没问题。

谢谢农哥指导！

应该是电源风扇什么的坏了

没看到明显的电源风扇有什么问题，只是感觉一个电源风扇的风小一点

单电源也是这样的现象

客户上的是双电源

人家说的很清楚。
其实也可能以前有过电源的问题，现在已经没有了。
从crontab中去掉这个定时提示，看看还有没有抱错。如果没有，就不是现在的错，是很久以前的，每12小时提示一次。

我这边也有这个报错
