How to Replace the Motherboard Assembly

The motherboard is shipped installed in a server module enclosure assembly. Do not remove the motherboard from the server module enclosure. Remove components from the old server module enclosure, and install these components into the new enclosure and motherboard assembly.

Before You Begin

• If you are replacing a motherboard that is not dead, obtain the BIOS and ILOM versions and download the system software release package (combined BIOS/ILOM) that incorporates those versions. A system software release package can be downloaded from: http://support.oracle.com.

• If you are replacing a dead motherboard, obtain the ILOM version and download the system software release package (combined BIOS/ILOM) that incorporates that version. A system software release package can be downloaded from: http://support.oracle.com.

• Backup the FRUID information before removing the motherboard. See How to Back Up FRU Information.

• For the location of components, see Illustrated Parts Breakdown.

1. Prepare the server module for service. See How to Prepare the Server Module for Service.
2. Remove reusable components from the server module motherboard.

   See the following procedures:

   • How to Remove the Service Processor Board

   • How to Remove DIMMs

   • How to Remove Flash Modules

   • How to Remove the Energy Storage Modules

   • How to Remove USB Flash Drives

3. Install the components on the new server module motherboard assembly.

   See the following procedures.

   • How to Install the Service Processor Board

   • How to Install DIMMs

   • How to Install Flash Modules

   • How to Install the Energy Storage Modules

   • How to Install USB Flash Drives

4. Prepare the server module for operation. See How to Prepare the Server Module for Operation.

   Note - Do not power on the server.

5. Place the server in standby power mode. See How to Power the Server Module to Standby Power Mode.
6. To restore FRUID information you collected earlier, log in to Service Mode.

   The Service Mode command-line prompt appears.

   #

7. At the prompt, type the following command:

   # copypsnc BACKUP1 PRIMARY

   This command copies the contents of the BACKUP1 container to the PRIMARY container.

8. To display the contents of the PRIMARY container, enter the following command:

   # showpsnc

   The contents of the PRIMARY container appears.

   ---

   Note - The motherboard MAC address (MACADDR element in the Primary column) that appears in the output is the MAC address of the motherboard that was removed from the system.

   ---

   You need to update the FRU MAC address, so the information is correct in the PRIMARY container.

9. To update the FRUID MAC address for the new motherboard, enter the following command:

   # setpsnc —m NEW_MAC_ADDRESS

   where NEW_MAC_ADDRESS is the MAC address of the new motherboard.

10. To backup the updated FRUID information, enter the following command:

    # copypsnc BACKUP1 PRIMARY

11. Power on the server module. See How to Power On the Server Module to Full Power Mode.
12. Update the system with the BIOS/ILOM firmware package you downloaded earlier.

    This will ensure that both the BIOS and ILOM firmware (which are packaged and tested together) are at a supported level.

    For information about updating firmware, see Oracle Integrated Lights Out Manager (ILOM ) 3.0 Supplement for the Sun Blade X6275 M2 Server Module.
