Remove the Motherboard Assembly

Before You Begin

Electrical

Caution - This procedure requires that you handle components that are sensitive to electrostatic discharge. This discharge can cause server components to fail.


  1. Run the ALOM CMT showrc command and make a note of any SP variables that have been modified from the factory default.
  2. Stop the Oracle Solaris OS to get the OpenBoot PROM prompt.
  3. Run the printenv command to make a note of any OpenBoot PROM variables that have been modified
  4. Power off the server.

    See Removing Power From the System.

  5. Remove the server from the rack.

    See Remove the Server From the Rack.

  6. Attach an antistatic wrist strap.
  7. Remove the top cover.

    See Remove the Top Cover.

  8. Remove the air duct.

    See Remove the Air Duct.

  9. Remove all PCIe/XAUI riser assemblies.

    See Remove a PCIe/XAUI Riser.


    Note - Make note of the location of expansion cards in PCIe/XAUI risers 0 and 1.


  10. Disconnect the motherboard-to-power distribution board ribbon cable.
  11. Disconnect the hard drive data cables:
    1. Press the latching mechanism on the connector to release the cable plug.

      If you have difficulty releasing the cable plug, first push the plug slightly into the connector, then press the latching mechanism.

    2. Keeping the latching mechanism pressed, pull the plug from the connector on the hard drive backplane.

      Caution

      Caution - The hard drive data cables are delicate. Ensure they are safely out of the way when servicing the motherboard.


  12. If you are replacing the motherboard, remove the following components:
    • All FB-DIMMs. Note memory configuration so that you can install the FB-DIMMs in the replacement motherboard.
    • SCC Module.
  13. Using a No. 2 Phillips screwdriver, remove the four screws that secure the motherboard assembly to the bus bar.

    Hot

    Caution - Use care when removing the bus bar screws to avoid touching a heat sink, which can be dangerously hot.



    Note - Set the four screws aside. You must use these screws to attach the motherboard to the bus bar during installation.


  14. Loosen the captive screw securing the motherboard to the chassis.

    The captive screw is green, and is located to the left of the bus bar screws.

  15. Using the green handle, slide the motherboard toward the back of the system and lift it out of the chassis.

    Hot

    Caution - Some components on the motherboard might be hot. Use caution when handling the motherboard, especially near the CMP heat sinks.

    Figure showing the motherboard assembly.
  16. Place the motherboard assembly on an antistatic mat.
