How to replace a CPU & Heatsink in a Sun Blade X6270M3 Server Module or Netra X6270M3 Server Module.

Fix

CAP PROBLEM OVERVIEW: CPU & HEATSINK REPLACEMENT

DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)
X6270M3 Server Training.

Note: The removal/insertion CPU tool is new for the Sandy Bridge M3 product lines.  If you have not used this new tool before please make yourself familiar before attempting to use onsite.  The tool is not intuitive so reference the service manual before attempting this service action.

DELIVERY REQUIREMENT: Inmediate.

TASK COMPLEXITY: 1-FRU

TIME ESTIMATE: 60 minutes

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, customer should perform an orderly and graceful shutdown of applications and OS.  Then power off the server module.

A data backup is not a pre-requisite but is a wise precaution.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

1. Prepare the server for service.

a. Power off the server module.
b. Remove the server module from the chassis and lay it flat cover side up on an anti-static mat.

Caution - After removing the server from the chassis insert a filler panel into an empty slot to reduce the possibility of a system shutdown.

c. Attach an antistatic wrist strap.
d. Remove the top cover.

2. Removing a CPU.

a. Identify the location of the faulty CPU.  To identify a faulty CPU, press and hold the blue Fault Remind button on the motherboard (SW3001).  (LED is off: CPU is operating properly, LED is on (amber): CPU is faulty and should be replaced.)

b. Gently press down on the top of the heat sink to counteract the pressure of the captive spring-loaded screws that secure the heat sink to the motherboard.  Loosen the four Phillips captive screws in the heat sink for the faulty CPU.  Turn the screws counter clockwise alternately one and one half turns until they are fully removed.  Use a No. 2 Phillips screwdriver to alternately loosen each of the four spring-loaded mounting screws that secure the heat sink to the motherboard.

c. To separate the heat sink from the top of the CPU, gently wiggle the heat sink left and right, while pulling upward.  A thin layer of thermal compound separates the heat sink and the CPU.  This compound also acts as an adhesive.

Note –Do not allow the thermal compound to contaminate the work space or other components.

d. Place the heat sink upside downon a flat surface.

e. Use an alcohol pad to clean the thermal grease from both the bottom of the heat sink and the top of the CPU.

Caution –Handle CPU socket pins with extreme care. CPU and socket pins are very fragile.  A light touch can bend the CPU socket pins and damage the board beyond repair.

f. Disengage both CPU release levers by pushing down and moving it to the side away from the CPU, and then rotating the levers upward starting with the right level when standing in front of the server module.  Release the left lever second.

g. Lift the CPU pressure frame up to the fully open position.

h. This platform requires a custom removal/insertion CPU tool that comes with the CPU replacement FRU.  Push the removal/insertion tool button in the top center to unlock the tool.  Place the removal/insertion tool on top of the CPU.  Properly position the tool over the CPU socket and lower it into place over the CPU socket.  Ensure that the tool and CPU key corners are aligned.  To properly position the tool over the CPU socket, rotate the tool until the green triangle on the side of the tool is facing the front of the server and it is over the left side of the CPU socket when viewing the server from the front.

i. Click the tab on the removal/insertion tool to secure the tool to the CPU.  Press the release lever on the tool to release the center button and engage the CPU.  An audible click indicates that the CPU is engaged.

j. Lift the CPU out of the socket while it is still attached to the removal/insertion tool.  Grasp the tool by its sides and remove it from the server.  Turn the tool upside down and verify that it contains the CPU.

k. While holding the CPU tool up side down, press the center button on the tool to release the CPU.  Carefully grasp the CPU on the front and back edges, lift it out of the tool and carefully place the removed CPU into an antistatic container.

3. Installing the CPU.

a. Unpack the replacement CPU and place it on an anti-static mat.

b. Ensure that the two CPU socket release levers are in the fully open position and that the CPU pressure frame is in the fully open position.

c. Press the button in the center of the removal/insertion tool to the down position.  Turn the tool upside down, grasp the new CPU by its front and back edges and position the CPU (circuit side up) in the tool.  Ensure that the triangle on the corner of the CPU aligns with the triangle on the side of the CPU removal/insertion tool.  Lower the CPU into the tool.  Then press the tool release lever to release the center button and engage the CPU.  An audible click indicates that the CPU is locked in place.

d. Properly position the tool over the CPU socket and lower it into place.  Carefully align the CPU over CPU socket 0 or 1.  Ensure that the notches on the sides of the CPU align with the keys on the socket.  To properly position the tool in the CPU socket, rotate the tool until the green triangle on the side of the tool is facing the front of the server and it is over the left side of the CPU socket (when viewing the server from the front) and lower the tool into the CPU socket.

e. Press the center button in the tool down to release the CPU so that it is placed in CPU socket 0 or 1.

Caution – Do not press down on the CPU.  Irreparable damage to the CPU or motherboard might occur from excessive downward pressure.  Do not forcibly seat the CPU into the socket.  Excessive downward pressure might damage the socket pins.

f. Remove the processor removal/insertion tool.

g. Visually check the alignment.  Close the pressure frame ensure that the pressure frame sits flat around the periphery of the CPU.

h. Engage the release levers by rotating it downward and slipping it under the catch left first and then the right one.

4. Install the CPU Heat Sink Assembly.

a. 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.

b. Inspect the heat sink for dust and lint.

c. 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.

Caution – When handling the heat sink, be careful not to get the thermal compound grease on your fingers so as not to transfer the grease to other server components.

d. Lower the heat sink onto the CPU.

Caution – Avoid moving the heat sink after it has contacted the top of the CPU.  Too much movement could disturb the layer of thermal compound, causing voids, and leading to ineffective heat dissipation and component damage.

e. Tighten the Phillips screws alternately one-half turn until fully seated.

f. Install the server module top cover.

g. Insert the server module into the Sun Blade chassis.

h. Power on the server module and return the server to operation.
