• 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 replacing a defective microprocessor, you must obtain the following items for use during the
replacement procedure (see Chapter 5 "Parts listing, Types 7196 and 4258" on page 57):
– Alcohol wipes
– Thermal grease
• 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.
• 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.
To remove a microprocessor and heat sink, complete the following steps:
Step 1. Remove the cover (see "Removing the compute node cover" on page 986).
Step 2. Locate the microprocessor that is to be removed (see "System-board connectors" on page 20).
Step 3. Remove the solid state drives (see "Removing a solid state drive" on page 1020).
Step 4. Remove the solid state drive mounting sleeve (see "Removing the solid state drive mounting
sleeve" on page 1024).
Step 5. Remove the solid state drive cage and backplane (see "Removing the solid state drive cage and
backplane" on page 1022).
Step 6. Remove the hot-swap hard disk drives and hard disk drive bay fillers (see "Removing a hot-swap
hard disk drive" on page 1009).
Step 7. Remove the hard disk drive cage and backplane assembly (see "Removing the hard disk drive
cage and backplane assembly" on page 1007).
Step 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.
b. Use a screwdriver to loosen the screws on the heat sink, rotating each screw two full turns
until each screw is loose.
