急救：Netra t1405

硬件：Netra t1405  系统大概是：SUNOS 5.6

前面板FAULT黄色灯在闪，POWER灯绿色长亮，SYSTEM灯不亮，打开前面板右上角盖，看风扇不转，经过排除发现断开PSU3后风扇开始转了，

用25针串口线连接serial ports A没有输出，远程telnet无法连接，只好连接lom口，输出如下：
lom>environment
Fault  3Hz
Alarm1 OFF
Alarm2 OFF
Alarm3 OFF

Fans:
1 OK standby
2 OK standby
3 OK standby
4 OK standby

PSUs:

断开PSU3后：

大虾帮忙解读一下该怎么处理

大虾们对此问题都没有意见么，还是意见太多无从说起···

先换风扇，然后再看看吧
