Goal

Solution

In addition to removing the Motherboard in the event you need to replace it, it must also be removed to access and remove the following FRUs:

• Power distribution board

• T5220 Power supply backplane

• Paddle card

Power down the host system (using the front panel power button) or STOP or poweroff command from the SP's root/ILOM or SP's admin/ALOM command line interfaces, respectively.

Unplug the system's power cord(s)

Implement all the usual anti-static-discharge methods...

• Prepare an antistatic surface to set parts on during the removal, installation, or replacement process.

• Place ESD-sensitive components such as the printed circuit boards on an antistatic mat. The following items can be used as an antistatic mat:

• Sun ESD mat, part number 250-1088

• A disposable ESD mat (shipped with some replacement parts or optional system components)

• When servicing or removing server components, attach an antistatic strap to your wrist and then to a metal area on the chassis.

   

Retain the packaging materials from the replacement Motherboard assembly for us in returning the removed motherboard.

REMOVING MOTHERBOARD ASSEMBLY

1. Remove the top cover.

2. Remove the air baffle.

3. Remove all PCIe/XAUI riser assemblies.

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

4. Disconnect the motherboard to power distribution board ribbon cable.

5. Disconnect the hard drive data cables.

6. Push the plug into the connector.

7. Press the release button.

8. Remove the plug from the connector on the hard drive backplane.

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

9. If you are replacing the motherboard, remove the following components:

Caution: Some components on the motherboard might be hot. Use caution when handling the motherboard, especially near the CPU heatsink.

• SCC module.

• All FB-DIMMs (Fully Buffered Dual Inline Memory Module).

Take note of the memory configuration so that you can install the FBDIMMs in the replacement motherboard. It is recommended that you put each of the the FBDIMMs in the same locations they were in the removed motherboard.

10. Using a No.2 Phillips screwdriver, remove the four screws which secure the motherboard assembly to the bus bar.

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

11. Loosen the captive screw securing the motherboard to the chassis. The captive screw is coloured green, and is located to the left of the bus bar screws.

12. Using the green handle, slide the motherboard back and tilt the motherboard assembly to lift it out of the chassis.

Grab the handle and move the motherboard toward the back of the system and lift it out of the chassis.

13. Place the motherboard assembly on antistatic mat. Finally, put the removed motherboard assembly in the packing materials provided with the replacement motherboard.

INSTALLING THE MOTHERBOARD ASSEMBLY

1. Tilt the motherboard assembly to position it into the chassis. When you install the motherboard ensure that you position the board as far forward in the chassis as possible.

2. Position the motherboard so that its screw holes align with he chassis stand-offs.

3. Using the green handle and the back edge of the motherboard tray, push down firmly and equally while sliding the motherboard to the front of the chassis.

Tip: After installing the motherboard into the chassis, ensure that the motherboard is correctly seated by gently lifting upon the handles. If the board moves upward,then it is not correctly seated. Ensure that the motherboard trays is flush with the chassis floor. Also, check for binds and ensure that the bus bar screw wholes are correctly aligned with the bus bar at the front of the motherboard.

4. Tighten the captive screw that secures the motherboard to the front of its tray in the chassis.

5. Install the four #2 Phillips screws that secure the motherboard to the bus bar. The four screws that secure the motherboard to the bus bar are black in colour.

Note: When you reinstall the motherboard, or install a replacement motherboard, you must use the correct screws to attach the motherboard to the bus bar.

6. If you are installing a replacement motherboard, install the following FRUs:

• SCC module.

• All FB-DIMMs

Note: Only install the FBDIMMs in the slots (connectors) from which they were removed. It is recommended that you put each of the the FBDIMMs in the same locations they were in the removed motherboard.

7. Connect the hard drive data cables.

8. Install the air baffle.

9. Reinstall the motherboard to power distribution board ribbon cable.

10. Reinstall the PCIe and XUAI risers.

11. Replace the system's top cover.

12. Plug in the system's power cord(s).

If the system administrator would like the Host powered-up, that can be done using the front panel power button, or START or poweron command from the SP's root/ILOM or SP's admin/ALOM command line interfaces, respectively.
