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 prerequisite but is a wise precaution.

Replacing a CPU is a cold-service operation. You must power off the server and and remove the AC power cords from the system before you remove a CPU.

1. Consider your first step.

If you have not prepared for service, do so now. See “Preparing for Service” page 61 in Service Manual.

2. Review this information and complete these prerequisites in this order.

Rotate the Drive Cage to the Service Position on page 81
Remove HBA Super Cap
Remove the Air Duct on page 83
Remove a CPU on page 186

1. Prepare the server for service.

Power off the server and disconnect the power cords from the power supplies.
Remove the server from the rack.
1. 4-Post, 19-inch Hardmount Rack Instructions
  1. Support the weight of the server for removal.
  2. Loosen the center captive screw on the left and right rear support brackets.
  3. Remove the two screws securing each hardmount bracket at the front of the rack.
  4. Lift the server from the rack and set it aside on an antistatic mat.
2. 2-Post, 19-inch Hardmount Rack
  1. Support the weight of the server for removal.
  2. Remove the two screws that secure each rear plate to the back of the post.
  3. Loosen the two screws that secure each rear plate to the eyelets of the side bracket.
  4. Slide each rear plate out of the eyelets and set them aside.
  5. Remove the two screws from each side bracket at the front of the posts.
  6. Lift the server from the rack and set it aside on an antistatic mat.
Attach an anti-static wrist strap.

2. Remove the server Top Cover and rotate the Disk Device Cage.

Fully loosen the two captive screws at the rear of the top cover.
Slide the top cover backward about .50 inch (13mm), lift top cover straight up and off from chassis.
Note: If the top cover will not slide back, you may have to loosen or remove the top two screws on both the left and right rack support backet. These top screws cause the support backet to press against the top cover.
Disconnect the cables attached to the disk backplane and the cable attached to the USB board.
Fully loosen the four captive screws securing the drive cage to the chassis (use a No. 2 Phillips screwdriver).
Rotate the drive cage to the vertical position.

3. Disconnect the Oracle Storage 12 Gb/s SAS PCIe RAID HBA super capacitor cable (if installed) and the air baffle.

Grasp both ends of the HBA super capacitor cable connector, press in on the release latch, and then unplug the connector
Move all cables away from the top of the air baffle.
Fully loosen the thumbscrew on the left bracket for the air baffle.
Slide the left (L) thumbscrew bracket forward and off of the mounting pins and set the thumbscrew bracket aside.
Lift the air duct straight up and off the alignment pins. Set the air duct aside.

4. Remove the Faulty CPU

Remove the failed CPU from the motherboard.
Caution  - When you remove and install a CPU, a special tool is required for safe handling of the CPU. The CPU tool is provided in the Motherboard shipping package.
1. Gently press down on the top of the heatsink to counteract the pressure of the captive spring-loaded screws that secure the heatsink to the motherboard and loosen the four Phillips captive screws in the heatsink for the failed processor.
2. Using a No. 2 Phillips screwdriver, turn the screws counterclockwise alternately one turn until they are fully removed.
3. To separate the heatsink from the top of the processor, gently twist the heatsink left and right, while pulling upward, and then lift off the heatsink and place it upside down on a flat surface. A thin layer of thermal grease separates the heatsink and the processor. This grease acts as an adhesive.
4. Use an alcohol pad to clean the thermal grease from the underside of the heatsink. Be very careful not to get the thermal grease on your fingers.
5. Disengage the processor release lever on the right side of the processor socket (viewing the server from the front) by pushing down on the lever and moving it to the side away from the processor, and then rotating the lever upward.
6. Unhook the pressure frame release levers from the catches of the CPU socket and raise them upward to approximately 35 degrees.
7. Release the pressure frame by slightly lowering the right release lever and lifting the pressure frame up to the fully open position.
8. To remove the processor from the processor socket, use the CPU removal and replacement tool and perform the following steps:
  1. Position the tool over the CPU socket and lower it onto the CPU. The triangle on the side of the tool aligns with pin 1 of the CPU.
  2. Locate the button in the center of the top of the processor removal and replacement tool and press it to the down position.
  3. Press the release lever on the tool to release the center button and engage the processor. An audible click indicates that the processor is engaged.
    1. Grasp the tool by the sides and remove it from the server.
    2. Turn the tool upside down and verify that it contains the processor.
    3. While holding the processor tool up side down, press the center button on the tool to release the processor.
    4. Carefully grasp the processor by the front and back edges, lift it out of the tool and place it with the circuit side down (the installed orientation) onto the antistatic mat.
    5. Carefully clean the thermal grease off the top of the processor.
Install the replacement CPU.
1. To install the processor in the processor socket, use the CPU removal and replacement tool and perform the following steps:
  1. Press the release button on the CPU tool to open the securing clips.
  2. Turn the tool upside down and lower the CPU into the tool, pin side up. The triangle on the side of the tool aligns with pin 1 of the CPU.
  3. Press the hold lever outward to engage the CPU. You will hear a click, and the release button retracts.
  4. Position the tool over the CPU socket and lower it into place. The triangle on the side of the tool aligns with pin 1 of the CPU socket.
    Caution - The tool must be level and flat onto the socket, not offset or angled.
  5. Press the release button on the tool to release the CPU into the socket.
    Caution - Do not attempt to forcibly seat the CPU.
  6. Remove the tool. The processor should lie flat in the socket, and be properly aligned.
2. Lower the pressure frame to the closed position. The pressure frame should sit flat over the processor.
3. Lower the release levers and hook them under the catches of the CPU socket.
4. Use the syringe to apply approximately 0.1 ml of thermal compound to the top center of the CPU.
  Note - Do not distribute the compound. The spring pressure of the heat sink will evenly distribute the compound.
5. Carefully align the heat sink screws to the mounting posts. The “System Front” label must face the front of the server.
  Caution - Moving the heat sink too much unevenly distributes the thermal compound and can lead to CPU damage.
6. Tighten the four captive screws of the CPU heat sink. Alternate between the screws in an X pattern, turning each one-half revolution, until they are fully seated.

5. Reinstall the air baffle, rotate/secure drive cage, reconnect HBA supercap cable and reconnect cables:

Reinstall the main air duct.
1. Move any loose cables to the gap between the DIMMs and the chassis walls.
2. Align the air duct to where it installs into the chassis.
3. Lower the air duct onto the alignment pins.
4. Set the left (L) thumbscrew bracket over the alignment pins and slide it rearward. Tighten the thumbscrew.
5. Route The USB cable into the cable trough in the PSU Air Duct
Lower the drive cage to the horizontal position. Tighten the four screws securing the drive cage to the chassis.
Connect the cables to the drive backplane, and the cable attached to the USB board. Plug each cable into its connector until you hear an audible click.
Complete the routing of each cable into the appropriate cable clamps.
Reconnect the RAID HBA super capacitor cable.
Reinstall the air filter
1. Set the bottom edge of the filter into the lip at the front of the chassis. The left and right release levers are facing forward.
2. Pivot the filter to vertical. The release levers snap the filter into place.
Install the top cover
1. Position the top cover on the chassis, with the front edge of the top cover 0.5 in. (13 mm) rearward of the front edge of the chassis.
2. Slide the top cover forward into place.
3. Secure the top cover with the two captive screws at the rear.
Reinstall or tighten the side bracket support screws.

6. Return the Server to operation.

Remove any anti-static measures that were used.
Return the server to it's normal operating position within the rack.
Re-install the power cords and any data cables that were removed.
Power on server. Verify that the Power/OK indicator led lights steady on.

7. Verify the CPU module is recognized and functioning.

In Oracle ILOM, check the health of the CPUs.

Replace x with 0 or 1.
->show /System/Processors/CPUs/CPU_x

    Properties:
        health = OK
        health_details = -
        part_number = 060F
        serial_number = Not Available
        location = P0 (CPU 0)
        model = Intel(R) Xeon(R) CPU E5-2699 v3 @ 2.30GHz
        max_clock_speed = 2.300 GHz
        total_cores = 18
        enabled_cores = 18
        temperature = Not Supported

->show /SYS/MB/Px

/SYS/MB/P0/PRSNT
    Targets:

    Properties:
        type = Entity Presence
        ipmi_name = P0/PRSNT
        class = Discrete Sensor

        alarm_status = cleared

/SYS/MB/P0/SERVICE
    Targets:

    Properties:
        type = Indicator
        ipmi_name = P0/SERVICE
        value = Off

8. Check ILOM event log to see if any new errors are reported and past faults are cleared/repaired.

-> show faulty
-> show /SP/faultmgmt
-> show /SP/logs/event/list
