本章介绍了设备启动故障的处理方法。
启动后串口无输出或输出乱码
设备无故重启
启动后串口无输出或输出乱码
故障现象
启动后配置终端无显示信息或者输出无法阅读的乱码。
可能原因
设备电源故障,整机未上电。
串口参数配置错误。
配置线缆连接故障。
定位思路
查看设备面板指示灯,确认是否电源故障。
核对串口参数,确认是否配置正确。
重新插拔线缆或更换线缆,确认是否线缆故障。
处理步骤
查看设备面板指示灯。如果Power灯是亮的,则排除电源故障。否则可确定为整机不上电,请参见设备不上电。
查看选择的COM口是否为正确的COM口,并且PC端的物理属性是否与串口的物理属性保持一致。缺省参数如下:
波特率:9600
数据位:8
停止位:1
奇偶校验位:无
流控:无
确认串口线缆连接牢固,可以考虑更换一根确定之前使用没有问题的串口线缆。如果故障现象排除,则确认为线缆出现故障。
设备无故重启
故障现象
设备无故重启或者反复重启。
可能原因
设备死循环重启或异常重启。
设备硬件损坏或系统软件bug问题。
处理步骤
排查是否触发某些功能导致了设备重启,包括U盘开局、CWMP、Autoconfig。
请执行命令display reset-reason查看重启原因。
