DISPATCH INSTRUCTIONS
WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?: M12 systems training
TIME ESTIMATE: 60 minutes
TASK COMPLEXITY: 3

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:
PROBLEM OVERVIEW: Motherboard Faulty

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.

The customer should conduct an orderly software system shutdown.

WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE?:

Caution - There is an electrical hazard if the power cords are not disconnected. All power cords must be disconnected to completely remove power from server.

An electromagnetic strap/map is required when working with internal hardware.

Note: The weight of the CPU memory unit is 17 kg (37.4lb) . Be sure to perform maintenance work by two people if it is mounted on the 24or higher U of the rack. If you work alone, you may be injured or the cabinet may be damaged.

Note - In the case of a dual power feed, make a note of the locations of the power cords before disconnecting them to ensure that they are reinstalled correctly.

In a single cabinet configuration the only way to replace is via "System/Stopped" method which entails all partitions be shut down / powered off with input power cords disconnected.
In a building block configuration, "Active/Cold" and "System Stopped" methods are available.

System Stopped maintenance
1. When you conduct cold or system-stopped maintenance, make sure that you set the mode switch of the operation panel to the Service mode before you start the maintenance.
2. Stop the entire system.
3. Execute the replacefru command to release the maintenance-target cabinet from the system.
4. Remove all power cords from the PSU backplane unit of the maintenance-target cabinet.

Active/cold maintenance
1. When you conduct active/cold or system-stopped maintenance, make sure that you set the mode switch of the operation panel to the Service mode before you start the maintenance.
2. Power off the maintenance-target physical partition.
3. Execute the replacefru command to release the maintenance-target cabinet from the system.
4. Remove all power cords from the PSU backplane unit of the maintenance-target cabinet.

Replacing CMU(U/l)
Caution - Be sure to wear an antistatic wrist strap before handling the components. If you perform the work without it, the electronic parts and the system may suffer serious damage.

1. Following steps are for equipment rack model 26xx or equipment rack model 16xx. Otherwise skip to step #2. Remove all crossbar cables from the the crossbar units. Use the hook-and-loop fastener to fix the crossbar cables to the cable holder to move the cables out of the way for CMU extraction.
2. Lower the cable support.

Note: Record the positions of the cables before removing them to ensure that they are reinstalled correctly.

3. Remove all the cables connected to the external interface on the rear of the cabinet.
4. Remove all the PCICSs from the Main Server Unit.
5. On the M12-2S - Remove the XBU from the Server by opening it's removal lever.
6. Remove the front cover

The serial number tag is afixed to the front cover insure the correct front cover go back on the correct M12

7. Remove the FANUs and then the FANBP.

8. Remove the HDDBP
9. Remove the PCIe cables from the cable guides and remove the PCIe cables from the CMUL. (the PCIE cables can break if roughly handled)
10. Bundle the PCIe cables using the provided cable clamps on the CMUU.

Note When removing either the CMUL or CMUU or both, be sure to bundle the PCIe cables using the cable clamps.
Removing the CMU without bundling PCIe cables may damage the cables due to interference with the internal components.

11. Loosen the fixing screws of the removal levers of the CMU(U/L).
12. Open the removal levers of the CMU(U/L). Then, hold the removal levers and pull out the CMU(U/L) until you see "HANDLING POSITION" on the sides of the CMU(U/L).
13. Hold the CMU(U/L) at HANDLING POSITION, and remove it from the server main unit.
14. Place the CMU(U/L) on a static mat and remove the memory by pressing downwards on the levers on either side of the DIMM's.
15. Reinsert the memory into the new CMU(U/L) in the order it was removed. Verify the levers on the sides of the slots are in the open position and gently press down on the DIMM.
16. Verify the PCIe cables on the new CMU(U/L) are properly bundled and clamped. Then grasp the new CMU(U/L) at "handling position arrows" on the unit sides and slide it into the chassis.

17. Insert the CMU(U/L) into the chassis.
           Hold it at "HANDLING POSITION", with the PCIe cables bundled with cable clamps and the CMU(U/L) removal levers open.
           Insert the CMU(U/L) by pushing the flat parts of the removal levers, with the levers open, until the CMU(U/L) stops inside the chassis.
           Then, close the removal levers and tighten the fixing screws to secure the CMU(U/L) to the chassis.

18. Connect the PCIe cables to the CMUL. Labels will direct you to the proper destination and route the PCIe cables through the cable guides inside of the chassis.
19. Install the HDDBP in the chassis. Make sure it is engaged in the positioning guide before you slide it in.
20. Install FANBP and secure it to the chassis and then reinstall all FANU's.
21. Install the XBU and tighten it's fixing screws.
22. Install the PCICS and the press down it's removal levers. Then lower the cable support to secure it in the chassis.
23. Connect the power cord which will return the server to a "hot state"

23a. Set autoboot to false:
Example: XSCF> setpparparam -p 0 -s bootscript "setenv auto-boot? false"

23b. Execute the setpparmode(8) command to deactivate the Autoboot function of the guest domain.
Example: XSCF> setpparmode -p ppar_id -m guestboot=off

23c. Start the system
Example: XSCF> poweron -a

23d. Enable RAID volume to check the status.
Execute the probe-scsi-all command to confirm that the RAID volume is not in the list.
Select a device to display the volume information and check that it is not enabled.

Example: {0} ok select /pci@8000/pci@4/pci@0/pci@0/scsi@0
{0} ok show-volumes

19e. Execute the activate-volume command to enable the RAID volume.
Example: {0} ok 0 activate-volume

22f. Execute the show-volumes command to check that the RAID volume is enabled
Example: {0} ok show-volumes

23. Switch the mode switches of the master cabinet and cabinets whose XSCFs are in the standby state to the Locked mode.
24. Execute the setdate command to set the XSCF clock if needed

OBTAIN CUSTOMER ACCEPTANCE
WHAT ACTION DOES THE FIELD ENGINEER/ADMINISTRATOR NEED TO TAKE TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?:
Have customer boot the system and confirm system state before leaving site.
