Chapter 6 Replacement of CPU/Memory Board Unit (CMU), CPU Module, and DIMM 6-23
6.4.1 Notes on CPU Module Replacement
This section describes important information needed prior to replacing the CPU module, and
the operating precautions in the replacement.
6.4.1.1 CPU Module Insertion/Extraction Tool
To replace the CPU module, use the CPU module insertion/extraction tool. This is a tool
used for securing the CPU module to a CMU, or removing the CPU module from a CMU.
The CPU module insertion/extraction tool is stored inside the server. In the M8000 server,
the tool can be found on the left-side wall when the front door of the server is open. In the
M9000 server base cabinet, the tool can be found on the upper part of the unit when the rear
door is open. In the M9000 server expansion cabinet, there is no insertion/extraction tool.
As shown in the figure, one end of the CPU module insertion/extraction tool is for insertion,
and the other end is for extraction. Be sure to use the tool in the correct orientation for the
work.
