SUN小型机T系列设备更换主板操作步骤

SUN T4-1设备更换主板操作指导

适用范围：SUN T4\T5系列设备适用环境：SUN T4设备主板故障需要更换主板故障涉及范围：修改默认启动设备路径

准备工作1.1工具准备：串口线、console线、镙丝刀1.2软件准备：CRT或其它远程管理登录软件、Oracle System Handbook

2.收集故障设备信息2.1 设备可以正常启动系统在系统中收集以下信息：

prtdiag –v 查看主板及各部件状态

# dmesg 查看系统启动信息 # eeprom 查看eeprom设置信息

eeprom

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Warning: Product identification data missing. System may not function properly.Service must update product identification data. Contact Service immediately.

Unrecognized Chassis: This module is installed in an unknown or unsupportedchassis. You must upgrade the firmware to a newer version that supportsthis chassis.
