2、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
3、。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。P
4、1-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。P7-720图1-1 Power720/740 内部结构图表1-1 P720/740 各型号配置对应内存盒位置及安插顺序机器型号及CPU模块个数内存板的安插顺序P720 8202-E4B or 8202-E4C只支持一个CPU模块1.

8、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Pow
