FIELD ENGINEER INSTRUCTIONS

PROBLEM OVERVIEW: SPARC T3-2 Server, Motherboard replacement.

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

1. Prepare for servicing:
a. Attach an antistatic wrist strap.
b. Power off the server and unplug power cords from the power supplies.
c. Extend the server to maintenance position.
d. Remove the top cover.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

Removing the MotherBoard.

1. Remove the System Configuration PROM from the motherboard so you can reinstall it on the new otherboard.
2. Remove all memory risers and filler panels.
3. Remove the System Remind button assembly (air divider) by lifting it up and away from the power supplies.
4. Disconnect all cables connected to the motherboard by completing the following tasks.
a. Disconnect two cables that connect the motherboard to the hard disk drive backplane.
b. Disconnect three cables from the motherboard.
c. Disconnect the fan board power cable and the ribbon cable from the motherboard.
5. Remove the Phillips screw on the cable cover, lift and remove the cover, and disconnect the two exposed cables from the motherboard.
6. Remove the four bus bar screws securing the motherboard to the power supply backplane.
7. Remove all PCIe cards from the server.
8. Position the HDD end of the cables off to the side using the tab on the top of the plastic power supply cover.
9. Remove the motherboard by completing the following tasks.
a. Loosen the captive screw in the corner near the fans that secures the motherboard to the chassis.
b. Grasp the handle on the motherboard and slide it toward the front of the chassis.
c. Lift the motherboard out of the chassis.
10. Remove the service processor from the motherboard so you can reinstall it on the new motherboard

Installing the Motherboard

1. Unpack the replacement motherboard and place it on an antistatic mat.
2. On the replacement motherboard, install the service processor that you removed from the old motherboard.
3. Grasping the motherboard by the handle, place it into the chassis.
4. Hold the cables off to the side while grasping the handle on the motherboard and sliding it toward the back of the chassis.
5. Reinsert and tighten the four bus bar screws that secure the motherboard to the power supply backplane.

Note: Using a No. 2 screwdriver, tighten the bus bar screws until the power supply backplane and the motherboard securely fasten to the bus bars.

6. Reinstall the System Remind button assembly (air divider) by sliding it into the chassis.

Caution: After replacing the motherboard, inspect the dividing wall gasket, and then install the plastic dividing wall securely. This dividing wall maintains a pressurized seal between the server cooling zones. Without this pressurized seal, the power supply fans will not be able to draw enough air to cool the drives properly.
7. Reinstall all memory risers.
8. Reinstall the cable cover.
9. Reconnect all cables from the power supply backplane, hard disk drive backplane, and fan board to their original locations on the motherboard.
10. Reinstall all PCIe cards.
11. Tighten the captive screw in the corner near the fans that secures the motherboard to the chassis.
12. On the replacement motherboard, install the System Configuration PROM that you removed from the old motherboard.
13. Install the top cover.
14. Return the server to the normal rack position.
15. Reinstall the power cords to the power supplies.
16. Prior to powering on the server, connect a terminal or a terminal emulator (PC or workstation) to the service processor SER MGT port.

NOTE: If the service processor detects the host firmware on the replacement motherboard is not compatible with the existing service processor firmware, further action will be suspended and the following message will be displayed:

Unrecognized Chassis: This module is installed in an unknown or unsupported chassis. You must upgrade the firmware to a newer version that supports this chassis.

If you see the preceding message, continue to Step 17. Otherwise, skip to Step 19.
17. Download the system firmware.
a. If necessary, configure the service processor NET MGT port so that it can access the network.
b. Log in to the service processor through the NET MGT port.
c. Download the system firmware.
Follow the firmware download instructions in the Oracle ILOM documentation.

NOTE: You can load any supported system firmware version, including the firmware version that had been installed prior to replacing the motherboard.
NOTE: Re-activate any RAID volumes that existed prior to replacing the motherboard. Only perform this task if your system had RAID volumes prior to replacing the motherboard. For details refer to doc 1387771.1 and the SPARC T3-2 Service Manual.

18. Power on the server.

OBTAIN CUSTOMER ACCEPTANCE

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

Boot system and monitor boot sequence for errors. Test functionality of system:
1. Run the Solaris "fmadm faulty" and SP/ILOM "show faulty" command (if only ALOM is supported run "showfaults -v" command) to verify that the fault has been cleared.
2. Perform one of the following tasks based on your verification results:
   * If the previous steps did not clear the fault, refer to doc 1004229.1 for information about the tools and methods you can use to diagnose and clear component faults.
   * If the previous steps indicate that no faults have been detected, the component has been replaced successfully. No further action is required
3. Restart software applications per applicable administration guides to resume system operation.
