  6. Remove the server's mid-wall by loosening the four green captive screws that secure the mid-wall to the server's chassis. Then lift the mid-wall slightly up and toward the front of the server to disengage it from the mushroom standoffs that are located on the server's chassis sidewall (one on each end of the mid-wall).
  7. Remove the motherboard from the server's chassis by grasping the middle of the air duct in the front and back and slide the motherboard toward the front of the server then lift it slightly to disengage the six mushroom standoffs that are located on the server's chassis under the motherboard.
  8. Lift the motherboard out of the server's chassis and place it on an anti-static mat, and next to the replacement motherboard.
  9. Remove the following reusable components from the motherboard and install them on the replacement motherboard.
    1. Internal USB flash drives (remove plastic cover by CPU location P1 for access).
    2. Make sure to install each USB flash drive in the same orientation to ensure that it is properly positioned in the USB port.
    3. DDR3 DIMMs. Perform a one-to-one replacement of the DIMMs from the current motherboard to the new motherboard to reduce the possibility of the DIMMs being installed into the wrong slots. If the DIMMs are not populated correctly the server performance may suffer and some DIMMs might not be used.
    4. To remove the DIMMs rotate both DIMM socket ejectors outward as far as they will go.
    5. Carefully lift the DIMM straight up to remove it from the socket.
    6. Install the DIMMs in the replacement Motherboard by ensuring that the ejector tabs of the DIMM slots are in the open position.
    7. Then align the notch in the DIMM with the key in the connector.
    8. Push the DDR3 DIMM into the connector until the ejector tabs lock the DIMM in place.

6. Remove the CPU(s) from the current Motherboard. Perform the following steps for each installed CPU.

  1. 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.  Using a No. 2 Phillips screwdriver turn the screws counter clockwise alternately one and one half turns until they are fully removed.
  2. 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.
  3. Place the heat sink upside down on a flat surface.
  4. 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.
  5. 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 lever (when viewing server from the front).  Repeat with left lever.
  6. Lift the CPU pressure frame up to the fully open position.
  7. 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.
  8. 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.
  9. 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.
  10. Leave the CPU in the removal/insertion tool and proceed to next step to install it into the new Motherboard.

7. Re-install the CPU(s) onto the new Motherboard. Perform the following steps for each CPU.

  1. 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.
  2. The CPU removal/insertion tool should have the CPU installed in it from the previous step after removing it from the current motherboard.
  3. Properly position the tool over the CPU socket and lower it into place.  Carefully align the CPU over the CPU socket.  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 server from the front) and lower the tool onto the CPU socket.
  4. Press the center button in the tool down to release the CPU so that it is placed in the CPU socket. 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.
  5. Remove the processor removal/insertion tool.
  6. Visually check the alignment.  Close the pressure frame ensure that the pressure frame sits flat around the periphery of the CPU.
  7. Engage the release levers by rotating them downward and slipping them under the catch left first and then the right one.

8.Install the CPU Heat Sink Assembly.

  1. 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.
  2. Inspect the heat sink for dust and lint. Clean if necessary.
  3. 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. 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.
  4. 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.
  5. Tighten the Phillips screws alternately one-half turn until they are fully seated.

9. Re-install the Motherboard into the Chassis.

  1. grasp the middle of the air duct in the front and back and tilt the front of the motherboard up slightly and push it into the opening in the rear of the server's chassis.
  2. Lower the motherboard into the server's chassis and slide it to the rear until it engages the six mushroom standoffs located on the server's chassis under the motherboard.
  3. Ensue that the indicators, controls and connectors on the rear of the motherboard fit correctly into the rear of the server's chassis.
  4. Install the server's mid-wall. Ensure that the cables (SAS and DVD cable, if applicable), are running through the opening in the center of the mid-wall.
  5. Position the mid-wall with cables in front of the motherboard so that it engages the mushroom standoffs that are located on the server's chassis sidewall (one for each side of the mid-wall).
  6. Place the FIM cable and the disk backplane power cable along side the mid-wall next to their respective motherboard connectors.
  7. Ensure that FIM cable and the disk backplane power cable are not pinched by the mid-wall and that they run beside the mid-wall and not under it; otherwise, the cables might be damaged.
  8. To secure the mid-wall to the server's chassis, tighten the four green captive screws.
  9. Carefully place the SAS cable(s) that you disconnected from the internal HBA into the cable trough provided by the air duct on the motherboard.
  10. If the server has a DVD drive, carefully place the DVD drive cable into the cable trough provided by the air duct on the motherboard and reconnect the DVD drive cable to the motherboard.
  11. Reconnect the front indicator module (FIM) cable to the motherboard.
  12. Reconnect disk backplane LED cable to the motherboard.
  13. Reconnect the disk backplane power cable to the motherboard.

9. Re-install the PCIe risers and PCIe cards.
