3收集信息完毕，关闭操作系统，关闭电源，按照handbook更换步骤更换主板
3.1 将更换前设备主板拍照记录内存位置，线缆连接情况
3.2 将故障主板内存条拆下按原位置安装到新主板内存插槽
3.3 拧开机器尾部PCI挡板两颗镙钉，拆下PCI卡上面挡板，拆下PCI卡
3.4 拧开主板顶端位置5颗镙钉，拔掉机器与主板连接线缆。
3.5 取下故障主板，安装新主板到设备中，检查线缆连接、内存位置

4.设置设备自启动路径
4.1设备加电,记录开机启动日志。
-> start /SYS
-> start /SP/console

4.2 如果更换的是新主板，原SP（ILOM卡）可能与主板firmware版本不匹配，信息如下： 需要升级firmware版本或更换回故障主板SP卡
