如果更换内存，以Pair(1组2根)的方式进行更换，更换的槽位为P1-Cn-C2 and P1-Cn-C7.

二、故障处理

2.1.先决条件

注意

确保系统关机，电源断开 操作时，使用防静电护腕 添加或更换硬件组件之前请作好数据备份。如果部件未正确安装，则可能会导致数据丢失。

2.2.准备项

准备确认项
类型	准备项	状态
硬件	笔记本一台	已准备就绪
	网线一根	已准备就绪
	一字、十字螺丝刀各一把	已准备就绪
	防静电护腕一个	已准备就绪
	新内存4根	已准备就绪
软件	HMC环境	已准备就绪
其它

2.3.操作项

操作项列表
序号	操作项	操作内容	状态
1	确认系统关机	建议客户应用及业务数据备份
2	佩戴防静电护腕	确认已经佩戴防静电护腕，并且防静电护腕连接到机柜上的未涂漆部分
3	断开电源	断开主电源和次电源
4	移除服务检修盖
5	拆除处理器板
6	将取下的处理器板放置在防静电的材质表面
7	拆开移除处理器前盖
8	确认更换内存位置
9	从防静电包装中取出内存
10	安装内存
11	重新安装处理器板
12	确认故障影响消失	确认新更换的硬件无告警
		确认新的硬件在系统中就绪
		用户确认应用及业务数据不受影响
13	收尾	清理现场，结束工作

三、参考信息

Processors and memory	Where to install memory modules
Memory plugged in pairs	Plugthe first pair of memory modules into memory module slots P1-Cn-C2 andP1-Cn-C7. Plug the second pair of memory modules into memory module slotsP1-Cn-C4 and P1-Cn-C9. Important: Memory modulesinstalled on the same processor assembly must be identical in size, speed, andfeature code. After the second pair of memory modules, the memory modulesbecome a quad.
One processor card, memory plugged in quads	・Plug the first quad of memory modules into memory module slotsP1-Cn-C2, P1-Cn-C4, P1-Cn-C7, and P1-Cn-C9. ・Plug the second quad of memory modules into memory module slotsP1-Cn-C1, P1-Cn-C3, P1-Cn-C6, and P1-Cn-C8. Important: Memory modulesinstalled on the same processor assembly must be identical in size, speed, andfeature code. After the second pair of memory modules, the memory modulesbecome a quad.
Multiple processor cards, memory plugged in quads	Memoryshould be balanced on each processor card, unless you have an odd number ofmemory modules. ・Plug the first quad of memory modules into memory module slotsP1-Cn-C2, P1-Cn-C4, P1-Cn-C7, and P1-Cn-C9 on each processor card. ・Plug the second quad of memory modules in slots P1-Cn-C1,P1-Cn-C3, P1-Cn-C6, and P1-Cn-C8 on each processor card. Important: Ensure that thememory modules installed on the same processor assembly are identical in size,speed, and feature code. However, memory module feature codes can be differentbetween processor assemblies.
