If you have replaced a server component or installed an optional device in the server, you need to reconnect
the power cords and all external cables, and turn on the server and peripheral devices.
Removing a microprocessor and heat sink
Use this information to remove a microprocessor and heat sink.
Read the safety information in “Safety” on page v and “Installation guidelines” on page 35.
If you are replacing a server component in the server, you need to turn off the server and peripheral devices,
and disconnect the power cords and all external cables.
The following notes describe the type of microprocessor that the server supports and other information that
you must consider when you install a microprocessor and heat sink:
• Microprocessors are to be installed only by trained technicians.
Important:
Always use the microprocessor installation tool to install a microprocessor. Failing to use
the microprocessor installation tool may damage the microprocessor sockets on the system board. Any
damage to the microprocessor sockets may require replacing the system board.
• Do not allow the thermal grease on the microprocessor and heat sink to come in contact with anything.
Contact with any surface can compromise the thermal grease and the microprocessor socket.
• Dropping the microprocessor during installation or removal can damage the contacts.
• Do not touch the microprocessor contacts; handle the microprocessor by the edges only. Contaminants
on the microprocessor contacts, such as oil from your skin, can cause connection failures between
the contacts and the socket.
• Do not remove the first microprocessor from the system board to install the second microprocessor.
• To order an additional optional microprocessor, contact your Lenovo sales representative or Lenovo
reseller.
Note:
Be sure to use the installation tool that comes with your microprocessor installation tool assembly.
The tools are similar in function and design, however Tool A has one setting for installing one size of
microprocessor, and supports the following families of microprocessors: E5-26xx, E5-46xx. Installation Tool
B has two settings for installing two different sizes of microprocessors. The settings that are marked on Tool
B are “L” for smaller low core microprocessors, and “H” for larger high core microprocessors. Installation
Tool B supports the following families of microprocessors: E5-26xx, E5-46xx, E5-26xx v2, E5-46xx v2.
Microprocessor Installation Tools A and B are shown in the following illustration.
