Lenovo Flex System x440 Compute Node Installation And Service Manual page 945

The following notes describe the type of microprocessor that the compute node supports and other
information that you must consider when you install a microprocessor:
• This component can be installed as an optional device or as a CRU. The installation procedure is the same
for the optional device and the CRU.
• The optional microprocessors are limited by the capacity and capability of the compute node. Any
microprocessors that you install must have the same specifications as the microprocessors that came
with the compute node.
• A socket cover and heat-sink filler or a microprocessor and heat sink must always be installed on
microprocessor sockets 1, 3, and 4. Microprocessor socket 2 will only have a socket cover when a
microprocessor is not installed. If the compute node has only one microprocessor, it must be installed in
microprocessor socket 1.
• If you are installing a second microprocessor, make sure that the microprocessors are identical.
• Before you install a new microprocessor, download and install the most current level of UEFI code (see
"Updating firmware and device drivers" on page
• When you install a second microprocessor, you might have to install additional memory or redistribute
memory across the DIMM connectors. See
• The microprocessor installation tool might become worn after several uses. Make sure that the tool can
hold the microprocessor securely if you are reusing an existing microprocessor installation tool. Do not
return the tool with other parts that you are returning.
• If you are installing a second microprocessor, the microprocessor option kit comes with a microprocessor
installation tool that you must use when you install a microprocessor. The microprocessor installation tool
comes with the replacement microprocessor installed on it and a cover over the microprocessor.
• If you are replacing a defective microprocessor, the CRU kit comes with one installation tool with the
replacement microprocessor installed on it and a cover over the microprocessor, and one empty
installation tool without a cover.
• If you are replacing a defective microprocessor, you must obtain the following items for use during the
replacement procedure (see
– Alcohol wipes
– Thermal grease
Attention:
1. Do not use any tools or sharp objects to lift the locking levers on the microprocessor socket. Doing so
might result in permanent damage to the system board.
2. Do not touch the contacts in the microprocessor socket. Touching these contacts might result in
permanent damage to the system board.
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.
