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: Faulty PSUBP

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

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.

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

Caution:
■ Remove the PCICS before removing the CMUL.
Replacing the CMUL with the PCICS installed may damage the PCICS or CMUL.

■ Before removing the CMUL or CMUU, bundle the PCIe cables of the CMUU in the specified procedure.
Removing the CMUL or CMUU without bundling the PCIe cables may damage the CMUL or CMUU.
For details, see "Chapter 17 Maintaining the CPU Memory Unit and Memory."

■ Remove the XBU before removing the CMUL or CMUU from the SPARC M12-2S.
Replacing the CMUL or CMUU with the XBU installed may damage the CMUL/CMUU or XBU.

■ If you have replaced the CMUL that has the hardware RAID function enabled, re-enable the hardware RAID volume.
For details, see "14.2.11 Re-enabling a Hardware RAID Volume" in the Fujitsu SPARC M12 and
Fujitsu M10/SPARC M10 System Operation and Administration Guide

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

■ 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.

Note: An electromagnetic strap/map is required to be used when working with internal hardware.

1. Verify the customer has removed the server requiring Service from the building block configuration.

2. 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.

3. Remove all power cords from the PSU backplane unit, (PSUBU) of the maintenance-target cabinet.

4. Remove the PSICSs from the server main unit. It is not necessary to remove the PCI Cards from the PSiCS. But note the location the were removed from in order to put them back in the right slot.

5. For M12-2S Remove the crossbar cables and the DUAL and BB cables

6. For M12-2S Remove the XBU, Loosen two fixing screws on the removal levers, and remove the XBU from the server main unit with the removal levers.

7. Remove the Front cover and FANUs and FANBP. Remove all the FANUs from the FANBP, and then remove the FANBP from the server main unit.

8. Remove the HDDBP. Remove the HDDBP from the server main unit.

9. Disconnect the CMUL and CMUU from the BPU. disconnect and stow PCI cables on CMUL. Loosen the fixing screws of the CMUL and CMUU, and pull them out to the chassis chassis opening.

10. Remove all the PSUs from the server main unit.

11. Remove the XSCFU. When the XSCFU has the LAN cable, serial cable, and USB memory connected to it, remove them all. Then, loosen the fixing screws of the XSCFU and remove the XSCFU from the server main unit

12. Enable the removal of the BPU from the chassis. Loosen the four fixing screws of the BPU.

13. Hold the BPU by the parts indicated on the unit and pull it out from the server main unit. Then, hold the BPU at the positions indicated by the "HANDLING POSITON" labels on its sides, and remove the BPU from the server main unit. Place the BPU on a static mat.

14. Remove the PSUBU from the BPU. Remove the connector cover. Loosen the fixing screw of the connector cover located on the left side of the BPU when you hold it, and Remove the connector cover from the BPU.

15. Remove the PSUBP and BPU connectors. There are two connectors that connect the BPU and PSUBP. First, close the latches on both sides of the connector and remove the connector. Next, pull out the other connector while pressing its latches.

16. Remove the PSUBP. Remove the three fixing screws and remove the PSUBP from the BPU.

17. If this is a BPU replacement reinstall the PSUBP to the replacement BPU. If this is a PSUBP replacement, install the replacement PSUBP to the BPU.

18. Reconnect the PSUB cables, (2) to the BPU.

19. Install the connector cover to the BPU, and tighten the fixing screw to secure the cover to the BPU.

20. Install the BPU. Insert the BPU while aligning the guides on the both sides of its bottom to the both sides of the inside of the chassis.

21. Secure the BPU. Tighten the four fixing screws.

22. Reinstall CMUL and CMUU tightening the fixing screws and the replacing PCI cables.

23. Reinstall HDDB. make sure that it is fitted to the positioning guide inside the chassis. If you install the HDDBP in an improper position, the HDDBP may be damaged.

24. Install the FANBP and FANUs. Install the FANBP and secure it to the chassis. Then, install all the FANUs. then install the front cover.

25. Install the XBU in the server main unit and secure it by tightening the fixing screws. install the xscfu and reconnect console cables.

26. Install the PCICS. Install the PCICS to the server main unit, and secure it by pushing down it's removal levers. Then, lower the cable support to secure the PCICS

27. Install the PSU's reconnect the the crossbar cables and the DUAL and BB cables for M12-2S models

28. Place the server main unit in the hot state. Connect the power cord to place the server main unit in the hot state

29. If this is "active cold" replacement follow the steps in 2248503.1 to reintroduce the server into the building block configuration.

30. Connect the cables. Connect the cables to the XSCFU, PCIe cards, and on-board I/Os. For the SPARC M12-2S in a multiple-BB configuration, connect the XSCF DUAL control cable and XSCF BB control cable.
31. Secure the cable support. Return the cable support to the original position and tighten the screws to secure it.
32. Start the XSCF.
33. Start the system
      Example: XSCF> poweron -a
34. Switch the mode switches of the master cabinet and cabinets whose XSCFs are in the standby state to the Locked mode.
35. Check the system status
      XSCF> showstatus
      XSCF> showhardconf -M

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.
