Solution


CAP PROBLEM OVERVIEW: CPU & Heatsink replacement

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:
Oracle Exalytics Server Training.

TIME ESTIMATE: 45 minutes

TASK COMPLEXITY: 3-FRU 

FIELD ENGINEER INSTRUCTIONS

WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :

If the system is still up and functioning, the customer should perform an orderly and graceful shutdown of applications and OS. 

A data backup is not a prerequisite but is a wise precaution.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare the server for service.


    

  1. Power off the server and disconnect the power cords from the power supplies.
    2. 

  2. Extend the server to the maintenance position in the rack.
    3. 

  3. Attach an anti-static wrist strap.
    4. 

  4. Remove the top cover.
    5. 



2. Identify the location of the faulty CPU


    

  1. The CPUs are numbered 0 to 3 from right to left when viewing the system from the front of the chassis.
    2. 

  2. Press the Fault Remind button on the air divider. If the CPU LED behind the CPU on the motherboard is off: CPU is operating properly. If the CPU LED behind the CPU on the motherboard is on (amber): CPU is faulty and should be replaced.
    3. 



2. Remove CPU and heatsink from the motherboard


    

  1. Unscrew the two Phillips screws from the heatsink. Turn the screws alternately one and one half turns until they are fully removed.
    2. 

  2. Twist the heatsink slightly to break the grease seal, lift off the heatsink and place it upside down on a flat surface to prevent the thermal grease from contaminating other components.
    3. 

  3. Use an alcohol pad to clean the thermal grease from both the bottom of the heatsink and the top of the CPU.
    4. 

  4. Disengage the CPU release lever by pushing down and moving it to the side away from the CPU, and then rotating the lever upward.
    5. 

  5. Open the load plate and carefully remove the CPU.
    6. 

  6. Place the CPU aside on an antistatic mat.
    7. 



3. Replace the CPU and heatsink on the motherboard.


    

  1. Properly orient the replacement CPU with the socket alignment tabs and carefully place each CPU into it's socket. Ensure that the orientation is correct as damage might result if the CPU pins are not aligned correctly.
    2. 

  2. Lower the load plate. Ensure that the load plate sits flat around the periphery of the CPU.
    3. 

  3. Engage the release lever by rotating it downward and slipping it under the catch.
    4. 

  4. Install the heatsink. If a new heatsink is being used then there is no need for additional thermal grease since a new heatsink will come pre-greased.
    5. 

  5. If the original heatsink is being used then use the syringe to apply thermal grease to the center of the top of the CPU.
    6. 

  6. Orient the heatsink so that the two screws line up with the mounting studs.
    7. 

  7. Carefully position the heatsink on the CPU, aligning it with the mounting posts to reduce movement after it makes initial contact with the layer of thermal grease.
    8. 

  8. Tighten the screws alternately one-half turn until fully seated.
    9. 



4. Return the Server to operation


    

  1. Replace the top cover
    2. 

  2. Remove any anti-static measures that were used.
    3. 

  3. Return the server to it's normal operating position within the rack.
    4. 

  4. Re-install the AC power cords and any data cables that were removed.
    5. 

  5. Power on server. Verify that the Power/OK indicator led lights steady on.
    6. 



 


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


 


TROUBLESHOOTING NOTE:


The minimum config for troubleshooting this server is 2 CPU's.


Populate CPU Slots 0 and 2, also a memory riser and pair of dimms for each CPU.
