TASK COMPLEXITY: 4

TIME ESTIMATE: 180 minutes

FIELD ENGINEER INSTRUCTIONS

Note the following points when replacing the MBU.
■ Do not replace the MBU and the PSUBP at the same time. If you replace the MBU and the PSUBP at the same time, the system may fail to operate correctly. Replace
   the MBU or the PSUBP, and then execute the showhardconf or showstatus command to verify that the replaced Field Replaceable Unit (FRU) is fully
   operational. Then, replace the other FRU. 

■ The CPU and XSCF on the MBU cannot be replaced individually. Replace the MBU.

■ When replacing the MBU, you need to remove memory from the old unit and reinstall it on the new unit. Always install the memory modules at the same
   locations as on the old motherboard unit.

■ Before replacing the MBU, execute the dumpconfig command to save the system setting information. When the MBU is replaced, CPU Activation setting
   information and CPU Activation keys may be deleted. To restore the CPU Activation setting information and CPU Activation keys that have been saved
   with the dumpconfig command, execute the restoreconfig command. For details, see "10.10 Saving/Restoring XSCF Setting Information" in the Fujitsu SPARC M12
   and Fujitsu M10/SPARC M10 System Operation and Administration Guide.

■ Set the system time. After replacing the MBU, you need to set the system time. For details, see "Notes on Maintenance of a CPU Memory Unit, Motherboard Unit, XSCF Unit, PSU  Backplane, or Crossbar Backplane Unit" in the Fujitsu SPARC M12 Product Notes of the latest XCP version.

■ Check the XCP version.  If you replace the MBU and switch the SD card, the CMU firmware versions
   displayed for Current and Reserve by the version command do not match when you check the XCP firmware version after executing the testsb command. This
   does not affect system operation. If you start the system when Current and Reserve are switched, the CMU firmware stored on the SD card is automatically
   applied. Fujitsu 174

■ When replacing the MBU, use the same type of FRU as the FRU mounted on the previous MBU. If you use a different type of FRU, it may not work properly.

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

Having a good data backup is not a pre-requisite but is a wise precaution.

MBU's are replaced using the "System/Stopped" method which entails all partitions be shut down / powered off with input power cords disconnected.

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

A. Accessing MBU
   1. Power off server using the poweroff -a command at the XSCF command prompt. Verify POWER LED is off, and disconnect power cords.
   2. Remove all cables from external interface block on rear panel.
   3. Slide server out from equipment rack.
   4. Open the Fan Cover
   5. Open and remove the fan cover.
   6. Remove the Upper Cover
   7. Remove the air duct and PSUBP cover.
   8. Remove memory from the old unit and reinstall it on the new unit. Mount the memory at the same memory mounting locations as those before replacement.

B. Removing MBU

   1. Remove all the FANUs
   2. Remove all the PCI Express (PCIe) risers.
   3. Release the cable lock guide.
   4. Remove the cables connected to the MBU.
      The following cables are to be removed:
        a. Three cables connecting the PSUBP to the MBU
        b. One cable connecting the PSUBP to the HDDBP  The cable does not have to be removed from the HDDBP.
        c. Two cables connecting the HDDBP to the MBU
        d. Two cables connecting the OPNL to the MBU
   5. Remove the five screws of the MBU.
   6. Hold the handles (A in Figure 16-6) of the MBU and slide it out toward the front of the SPARC M12-1.
       Confirm that the MBU disengages from 10 fixing pins.  Then pull it straight up.
       *** When removing MBU from server, take care not to damage the connector. ***
   7. Place the removed MBU on a grounded ESD mat to ground any static electricity
   8. Remove SD protective covers on the replacement and original MBU_A. then Insert Original SD card into the new MBU_A and the new SD card into the failed MBU_A  Replace protective covers.

C. Mounting MBU

   1. Hold two handles on the MBU and slide in while lowering to align with the mounting location from the front of the server.
   *** When mounting MBU in server, take care not to damage the connector. ***
   2. Confirm that the 10 fixing pins are inserted into the MBU, and then slide the MBU toward the rear of the SPARC M12-1
   3. Replace and tighten the five screws of the MBU.
   4. Connect the cables to the MBU.
       The following cables are to be installed: Note - Reinstall the cables in their original positions by referring to the record that you made before the start of maintenance.
       a. Three cables connecting the PSUBP to the MBU
       b. One cable connecting the PSUBP to the HDDBP
       Connect the cable to the PSUBP.
       c. Two cables connecting the HDDBP to the MBU
       d. Two cables connecting the OPNL to the MBU
   5. Store the MBU cables in the cable guide.  Store in the cable guide one cable (red/black) connecting the PSUBP to the
       HDDBP and two cables (black and black/yellow/white) connecting the OPNL to the MBU.  Lock the cable guide.
   6. Install all the PCIe risers.
   7. Install all the FANUs.

D. Reassembling Server

   1. Install the air duct and the PSUBP cover.
   2. Install the upper cover.
   3. Close the fan cover.
   4. Reconnect all cables to their original destinations.
   5. Power on server.
       Connect all power cords to power outlets.
       Verify that XSCF STANDBY LED on operator panel is on.
       Set mode switch on OPNL to desired mode position
   6. Check the version of XCP ( version -c xcp ) installed on the freshly replaced MBU,- make sure it matches the version of the XCP that was replaced,
       - update the XCP revision when applicable.  ( This can take upto 30 minutes or more. )
       NOTE: In order to download and install the XCP images on your system, please refer to the Web Users Interface (BUI) and  getflashimage  documentation to download an image on to the XSCF, and the flashupdate  documentation to install the XCP image on to the XSCF. 
       - After the replacement of the motherboard unit is completed, the system clock must be reset using setdate.

       Example> Set the current time to 2013-10-27 16:59:00 local time.
       XSCF> setdate -s 102716592013.00
       Fri Oct 27 16:59:00 MST 2013
       The XSCF will be reset. Continue? [y|n]:y

   7. Confirm hardware fix by running the following commands:

       XSCF> showhardconf -M
       XSCF> showstatus

OBTAIN CUSTOMER ACCEPTANCE

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

Verify functionality, no service LEDs or messages.
