rp8420更换VRM步骤
请问有更换过RP8420的CELL板上的VRM的兄弟么请问下这个PN号是多少啊，客户那机器还在运行，又不好打开进去看PN号，在MP中DF也没找到这个的PN号 现在客户那有个CELL板上的第9个VRM报错了，机器亮黄灯：
但是小弟没换过这个VRM，查看RP8420的手册上好像也没有这个更换的方法。听朋友说RP7420的GUIDE上有这个，请问RP7420和RP8420的VRM是一样的么？另外HP的网站访问起来太慢了，到现在还没下到7420的guide,麻烦如果有7420的service guide的兄弟提供个，谢谢

Removing a VRM
Step 1. Remove the right side cover. See “Removing and Replacing Covers” on page 116.
Step 2. Power off the cell board using the MP command menu PE command.
Step 3. Verify that the green power LED located on either the left-hand side or right-hand side of the cell
board is off before removing the cell board. See Figure 6-38 for the power LED locations.
Step 4. Press each extraction lever and slide the lock to the unlocked position. Pull the extraction levers
outward to unseat the cell board from the backplane connector. See Figure 6-16 on page 132.
Step 5. Slide the cell board from the chassis. See Figure 6-19 on page 135.
Step 6. Remove the memory and CPU covers.
Step 7. Locate the VRM to be replaced.
Step 8. Loosen the VRM retaining screws.
Step 9. Pull the VRM off the cell board.
Replacing a VRM
Step 1. Insert the new VRM into the socket.
CAUTION Check for proper pin orientation before inserting VRM.
Step 2. Tighten the screws until snug but do not over tighten.
Step 3. Replace cell board memory and CPU covers.
Step 4. Insert the cell board into the chassis.
Step 5. Restore power to the cell board and test.
Step 6. Install the right side cover.抱歉 没找到pn 十分感谢 请问有RP7420的SG么？ 回复 1# woailili9
rp8420上面有更换VRM的步骤，你这个是高电压的VRM，备件号为0950-4123（手册第174页）。不过手册没找到9号VRM的位置（手册的那张图少了些标示，注意共有15个VRM，分低压和高压），如果Cell板上面有标示最好（HP应该有的，可以问下800）。
rp8420手册（第148页是更换VRM的步骤）：

感谢版主的热心回答，谢谢，大概有数了。
还请问下，除了这种通过手册去查看PN号的方法外，这种VRM的PN号可以通过CSTM看到么？
另外：版主确定这块VRM是高压VRM模块是因为

这里提示是3.3V判断的是么？

对的，手册里面有提到。 版主强大，我也谢过版主了回复 5# lbseraph
前几天刚换了个RX 7620的VRMmp日志说的是slot13 low volt vrm 但是我在cell板上看到的vrm13电压输出是一点几伏到3点几伏吧，具体不记得了，应该是高压得，，，，坑
cell板上其他vrm倒是有0.8几到一点几伏的，应该是低压的。。。、
我换了之后一切正常，cm-ps里面也正常了（先前有VRM13温度过高的告警）
