DISPATCH INSTRUCTIONS
- WHAT SKILLS DOES THE ENGINEER NEED:X4170 M2 Server Training
- TIME ESTIMATE: 60 minutes
- TASK COMPLEXITY: 3

FIELD ENGINEER INSTRUCTIONS:
- PROBLEM OVERVIEW:CPU REPLACEMENT
- WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE
RESOLUTION ACTIVITY?:
If the system is still up and functioning, customer should perform an orderly and graceful shutdown of applications and OS
A data backup is not a pre-requisite but is a wise precaution.

Note: If this server is part of an Exadata, please follow shutdown instructions in Section 1 of DOC ID: 1539451.1

- WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

NOTE - 'If this is an Engineered system then the system administrator should prepare the system for service by performing any application related functions required to shutdown the node. This might include but is not limited to performing a system backup, failover of application or services, and finally a system shutdown.'

Prepare the server for service.
    a. Power off the server and disconnect the power cord (s) from the power supply (s).
    b. Remove the server from the rack.
    c. Attach an antistatic wrist strap.
    d. Remove the top cover.

Removing CPU

   a. To identify the location of the faulty CPU, press the Fault Remind button on the motherboard.
   b. The fault LED for the faulty CPU lights.
   c. Unscrew the two screws in the heat sink for the faulty CPU.
   d. Twist the heat sink slightly to break the grease seal, lift off the heat sink and place it upside down on a flat surface to prevent the thermal grease from
contaminating other components.
   e. Use an alcohol pad to clean the thermal grease from both the bottom of the heat sink and the top of the CPU.
   f. Disengage the CPU release lever by pushing down and moving it to the side away from the CPU, and then rotating the lever upward.
   g. Open the pressure frame and remove the CPU.

Installing CPU

    a. Properly orient the CPU with the socket alignment tabs and place the CPU into the socket.
        Ensure that the orientation is correct.
    b. Lower the pressure frame.
        Ensure that the pressure frame sits flat around the periphery of the CPU.
    c. Engage the release lever by rotating it downward and slipping it under the catch.

    d. Use the syringe to apply approximately 0.1 ml of thermal grease to the center of the top of the CPU.Do not distribute the grease.
    e. Inspect the heat sink for dust and lint.
    f. Orient the heat sink so that the two screws line up with the mounting studs.
    g. Carefully position the heat sink on the CPU, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease.

    d. Carefully position the heat sink on the CPU, aligning it so that the two screw align with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease.
    e. Tighten the screws alternately one-half turn until fully seated.

   - Return the server to operation.

OBTAIN CUSTOMER ACCEPTANCE
- WHAT ACTION DOES THE CUSTOMER NEED TO TAKE TO RETURN THE SYSTEM TO
AN OPERATIONAL STATE:

Boot up system and verify full functionality

Note: If this server is part of an Exadata, please follow restart instructions in Section 1, step 10 of DOC ID: 1539451.1
