Lenovo Flex System x280 X6 Compute Node Installation And Service Manual page 771

1. Read "Safety" on page v and "Installation guidelines" on page 699.
2. If the compute node is installed in an Flex System chassis, remove it (see
"Removing a compute node from a chassis" on page 701 for instructions).
3. Carefully lay the compute node on a flat, static-protective surface, orienting the
compute node with the bezel pointing toward you.
About this task
The following notes describe information that you must consider when you
remove a microprocessor:
v Each microprocessor socket must always contain a microprocessor and heat sink.
v 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.
v If you are replacing a defective microprocessor, you must obtain the following
items for use during the replacement procedure (see Chapter 5, "Parts listing,
Types 7903 and 4259," on page 59):
– Alcohol wipes
– Thermal grease
v 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.
v The microprocessor installation tool has the microprocessor installed on the tool,
and may have a protective cover over the microprocessor. Do not use the tool, or
remove the cover until you are instructed to do so.
Note: Be sure to use the installation tool that comes with your microprocessor
installation tool assembly.
Procedure
To remove a microprocessor and heat sink, complete the following steps:
1. Remove the cover (see "Removing the compute node cover" on page 715).
2. Locate the microprocessor that is to be removed (see "System-board
connectors" on page 17).
3. Remove the solid state drives (see "Removing a solid state drive" on page
750).
4. Remove the solid state drive mounting sleeve (see "Removing the solid state
drive mounting sleeve" on page 755).
5. Remove the solid state drive cage and backplane (see "Removing the solid
state drive cage and backplane" on page 752).
6. Remove the hot-swap hard disk drives and hard disk drive bay fillers (see
"Removing a hot-swap hard disk drive" on page 739).
7. Remove the hard disk drive cage and backplane assembly (see "Removing the
hard disk drive cage and backplane assembly" on page 737).
8. Remove the heat sink.
Attention: Do not touch the thermal material on the bottom of the heat sink.
Touching the thermal material will contaminate it.
a. Use a screwdriver to loosen the screw on one side of the heat sink to break
the seal with the microprocessor.
