引言
小型机内存为了保证其使用性能及可靠性，在插法上都有非常严格的要求，每一系列，每一型号的，甚至不同的配置都会出现各种不同插法，并严格限定配对槽位和安插顺序。本文档以Power7-720、Power6-520、Power5-55A、Power5-52A为例来说明内存安插规则及注意事项。

目录
引言 1
一、 Power7-720/740内存更换规则及注意事项 2
二、 Power6-520内存更换规则及注意事项 2
三、 Power5-55A内存更换规则及注意事项 2
四、 Power5-52A内存更换规则及注意事项 2

一、 Power7-720/740内存更换规则及注意事项
1、 准备工作: 准备好服务器信息（客户准备）、故障内存位置、内存备件、笔记本、网线、十字螺丝刀一把、一字螺丝刀一把。
2、 与客户到生产库房取内存备件，然后根据客户提供的信息，与客户一起，确认服务器位置、状态及是否关机，如未关机，向客户说明，协调进行关机。
3、 服务器关机后，首先进行服务器下电工作。
4、 下电之前，工程师务必再次确认服务器所在位置，可让两名工程师站在服务器所在机柜的前后，通过两名工程师上下计数方法确定服务器所在位置，确认无误后将服务器下电。
5、 服务器下电之后，将服务器后面的KVM IQ适配器、网线、光纤线、等连接线缆分别取下，注意光纤线和网线的左右顺序，千万不可混插，如果线缆太多可在取下前做好标记。
6、 服务器线缆整理完毕，需要将服务器从机柜中抽出，抽出前需要注意：
7、 首先，用工具将服务器前面板上的螺丝卸下，以便服务器能正常从机柜中抽出。
8、 两名工程师需站在服务器所在机柜的前后，后面的工程师负责检查服务器在抽出的过程中，是否会拖拽其他服务器线缆，此环节必须要仔细，前后工程师密切配合，避免造成其他事故。
9、 前面的工程师负责将服务器拉出到合适的位置。注意：如果服务器在机柜的中央以下位置，可不用将服务器下架，若服务器在机柜的顶部或中央以上，不方便更换备件，则必须将服务器下架后再更换故障内存。
10、 将服务器后面的两个螺丝松开，打开顶盖，可以看到P720/740内部结构如图1-1所示。P1-C15、P1-C16、P1-C17、P1-C18是4个内存盒，每个内存盒可以插8块内存。根据CPU个数的不同内存盒个数也有限制，720只支持最多两个内存盒，740一个CPU模块的支持两个内存盒，两个CPU模块的可支持4个内存盒。表1-1列出了P720/740 各型号机器对应内存盒的位置。

2. Install the second memory riser at location P1-C17.
3. Install the third memory riser at location P1-C16.
4. Install the fourth memory riser at location P1-C15.
11、 拔出需要更换的内存盒，方法如图1-2所示，按下A处向上拉起内存盒即可。

图1-2 拔出内存盒
12、 拔出后的内存盒后就可以开始更换内存了。根据我们事先对机器故障的判断，确定了故障内存的位置，图1-3显示内存的具体物理位置。然后根据机器配置情况，对照表1-2 Power7 8202-E4B or 8205-E6B型号的机器内存安插顺序，和表1-3 Power7 8202-E4C or 8205-E6C型号的机器内存安插顺序,查找配对规则，然后进行更换。

图1-3内存物理位置

注意：由于小型机的内存都是成对或者4个一组起作用的，故更换时也需要成对更换，而我们记录的故障位置可能只有一个，这是就需要判断与该故障内存成对的内存槽位。对于Power7 8202-E4B or 8205-E6B型号的机器内存安插顺序及槽位如表1-2所示。
