TASK COMPLEXITY: 3

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: An Oracle Server X5-4 CPU & Heatsink needs replacement

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

1. Orderly shutdown of applications on server
2. Full backup is recommended as a precaution
3. Shutdown of OS and power down of server

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Caution – These procedures require that you handle components that are sensitive
to static discharge. This sensitivity can cause the component to fail.

1.  Attach an antistatic wrist strap.

2.  Power off the server and remove power cords.

3.  Identify the failed CPU by pressing and holding the system fault remind button.

4.  Remove the two memory riser cards associated with the failed CPU.

5.  Loosen the four captive screws holding the heatsink in place. [Turn the screws in alternating one and one half turns until they are fully removed]

6.  To remove the heatsink, twist and lift the heatsink, breaking the seal created by the thermal compound.

7.  Remove the heatsink by lifting straight up and place it on your work space upside down.

8.  Clean all thermal paste from the heatsink.

9.  Clean all thermal paste from the CPU prior to attaching the CPU replacement tool for extraction.

10.  If you are installing a CPU into a CPU socket where a CPU has never been installed, remove the CPU cover plate:

10.1. Disengage the CPU release lever by pushing down and moving it to the side away from the CPU socket, and then rotating the lever upward.
10.2  Open the load plate and carefully remove the CPU cover plate.

11.  If the CPU LED behind the CPU on the motherboard is on (amber): CPU is faulty and should be replaced.

12. Remove the CPU:

12.1  Open the spring-loaded CPU load plate release levers by pushing them down and moving them slightly toward the CPU socket and away from their retaining clips

          The levers are numbered by their required order of operation. The left-side lever (when viewed from the front of the server) must be opened first.

12,2  Rotate the levers to the fully-open position.

          When the second lever is in its fully-open position, the load plate is unlocked.

12.3  To open the load plate, lift the unhinged end to its fully-open position.

          Caution  -  Component damage. The pins of the CPU socket can be easily damaged. To remove the CPU, use the correct CPU replacement tool

     To remove the CPU, use the CPU replacement tool:

     The tool is used to remove and install the CPU in the socket. The top side of the replacement tool has a button in the center and a tab on one side. Pressing down on the button opens the tool. Pressing the tab     closes the tool (and releases the button).

12.4  Press down on the release button on top of the replacement tool.

       This action opens the tool.

12.5  On one corner of the tool there is a label with a downward pointing triangle. Likewise, the CPU is marked with a triangle on one of its corners.

          This is a key that aligns the tool and the CPU with the CPU    socket. The tool and the CPU are correctly positioned with the socket when all of the triangles are aligned.

12.6  Orient the bottom of the tool over the CPU, ensuring that the triangle on the tool aligns with the triangle on the CPU.

12.7  Lower the tool onto the CPU, ensuring that it sits evenly on the CPU.

12.8  Push the release tab away from the center button.

          This action is accompanied by a click sound as the tool closes and grabs the CPU.

12.9 To remove the CPU, lift the tool upward and out of the server. 

13  Install the new CPU.

13.1 Unpack the installation kit.

■ CPU and pre-greased heatsink
■ Pre-greased heatsink only
■ CPU only, with syringe to apply thermal grease to existing heatsink

13.2 To install a CPU, use the CPU replacement tool.

13.3  Press down on the release button on top of the replacement tool. This action opens the tool.

Note: On one corner of the tool there is a label with a downward pointing triangle. Likewise, the CPU is marked with a triangle on one of its corners. This is a key that aids in correctly positioning the tool and the CPU with the CPU socket. The tool and the CPU are correctly positioned with the socket when all of the triangles are aligned.

13.4  Turn the replacement tool upside down, noting the corner of the tool that is marked with a triangle (alignment key).Note the corner of the CPU that is marked with a triangle (alignment key).

13.5  Lift the CPU by its edges, taking care not to touch the metal contacts on the underside of the CPU.

13.6  Turn the CPU upside down (metal contacts facing upward) and set it on the replacement tool, ensuring that the triangle on the CPU aligns with the triangle on the tool and that the CPU sits flat in the tool. Do not release your hold the CPU.

Note:  The CPU is not yet secured in the tool.

13.7  With the tool and the CPU in the topside down position, press the topside release tab outward, away from the center button.

13,8  This action is accompanied by a click sound as the tool closes and grabs the CPU. The CPU should now be secured in the tool.

13.9  Ensure that the CPU is secured in the tool.

Note: When the CPU is secured in the tool, there is no side-to-side movement of the CPU within the tool.

1. Turn the tool over, so that the CPU contacts are facing downward.

   This positions the tool with the topside facing upward.

2. Orient the tool so that the triangle on the tool aligns with the triangle on the socket.
3. Lower the tool onto the socket, ensuring that the CPU is correctly positioned and sits flat and evenly in the socket.

   When the CPU is correctly positioned, there is no side-to-side movement of the CPU within the socket.

14.4 Install the heatsink.

15. Return the server to operation

15.1 Install the top cover.

15.2 Power on the server.

OBTAIN CUSTOMER ACCEPTANCE

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

Login into SP and validate CPUs are seen or via IPMItool
Bring up system and check all CPUs are visible

TROUBLESHOOTING NOTE:

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

Servers with two CPUs have CPUs and heatsinks in sockets 0 and 1 and CPU cover plates installed in sockets 2 and 3.
This configuration requires four memory riser cards and an air baffle to control airflow for maximum cooling
