ACG1000-SE-PWR 开机无法启动问题排查

ACG1000-SE-PWR 设备刚刚到货，开机发现无法启动。

通过console 打印信息如下：

1，开始分析可能是版本损坏，建议开机按CTL + B 进入menuboot 然后从新来进行软件升级

2，如果menuboot 升级无法解决，可以判断是硬件故障

按照第一种办法进行测试发现无法进入bootmenu;

后来开始分析console打印信息，

是因为面板的reset 按钮卡主导致的不断重启，无法启动，现场将该按钮弄好后设备可以启动。

acg1000 真正的硬件问题在console 输出时一般会打印内存或者其他告警信息，像此局点这样的可以考虑是面板的

reset 按钮卡住导致的。
