• Before you replace microprocessor, download and install the most current level of UEFI code (see
"Updating firmware and device drivers" on page 27).
• 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.
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.
To install 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. Remove the solid state drives (see "Removing a solid state drive" on page 1020).
Step 3. Remove the solid state drive mounting sleeve (see "Removing the solid state drive mounting
sleeve" on page 1024).
Step 4. Remove the solid state drive cage and backplane (see "Removing the solid state drive cage and
backplane" on page 1022).
Step 5. 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 6. Remove the hard disk drive cage and backplane assembly (see "Removing the hard disk drive
cage and backplane assembly" on page 1007).
Step 7. If you are not installing a new microprocessor and a new heat sink, remove the thermal grease
from the heat sink and microprocessor; then, apply new thermal grease before installation (see
"Thermal grease" on page 1034).
Step 8. Open the microprocessor socket release levers and retainer.
a. Identify which release lever is labeled as the first release lever to open and open it.
