DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE ENGINEER NEED:(IS A SITE ENGINEER AVAILABLE?)
The engineer should be M12 trained

DELIVERY REQUIREMENT:
As scheduled

TASK COMPLEXITY: 2

Time Estimate: 45 minutes

FIELD ENGINEER INSTRUCTIONS

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

If 1BB configuration the replacement procedure will be System Stopped/Cold.

If > 1BB configuration have the choice of Active/Cold, Inactive/Cold, System Stopped/Cold

WHAT ACTION DOES THE ENGINEER NEED TO TAKE:

I. SYSTEM STOPPED/COLD REPLACEMENT STEPS FOR 1BB CONFIGURATIONS

1. Shutdown all Solaris instances and power "off" the system.

XSCF> poweroff -a

XSCF> showpparstatus -a

2. Remove power cables

3. Remove XBU crossbar cables

4. Loosen the two fixing screws of the XBU to release the removal levers.

5. Open the removal levers of the XBU, and disconnect the connector from the CPU memory unit.

6. Hold the top and bottom of the XBU with both hands, and remove the unit carefully from the server main unit.

Note - If the cable support is used, remove the XBU with the cable support lowered.

Note - Place the removed XBU on the ESD mat to ground any static electricity.

7. Installation is the reverse of the above procedure.

Note - When installing a XBU, check the connectors on the CPU memory unit and XBU
beforehand to confirm that none of the pins are bent and that all the pins are neatly arranged
in lines. If the XBU is installed with a bent pin in a connector, the CPU memory unit or XBU
may be damaged. When installing a unit, insert it carefully so as not to bend any pins.

II. INACTIVE/COLD REPLACEMENT STEPS FOR > 1BB CONFIGURATIONS

1. Check status of PPARs and LDOMs

XSCF> showpparstatus -a

XSCF> showdomainstatus -a

2. Stop the physical partition

-Checking the operation status of physical partitions

XSCF> showpparstatus -a

-Checking the operation status of the logical domains on the target physical partition

XSCF> showdomainstatus -p <ppar_id>

-Checking the status of the SPARC M12-2S requiring maintenance

XSCF> showboards -p <ppar_id>

-Stopping the physical partition

XSCF> poweroff -p <ppar_id>

-Checking the stop processing status of the physical partition

XSCF> showpparprogress -p <ppar_id>

-Confirming that the target physical partition has stopped

XSCF> showpparstatus -a

3. Release the target BB from running config

XSCF> replacefru

With a number key, select the BB requiring maintenance

4. Confirm standby LED on XSCFU and power off breaker

5. Remove power cables

6. Remove XBU crossbar cables

7. Loosen the two fixing screws of the XBU to release the removal levers.

8. Open the removal levers of the XBU, and disconnect the connector from the CPU memory unit.

9. Hold the top and bottom of the XBU with both hands, and remove the unit carefully from the server main unit.

Note - If the cable support is used, remove the XBU with the cable support lowered.

Note - Place the removed XBU on the ESD mat to ground any static electricity.

10. Installation is the reverse of the above procedure.

11. After connecting the cables of the SPARC M12-2S that has undergone maintenance to the building block configuration, connect the power cable and add the building block back into config

by finishing the "replacefru" procedure. Do not enter “f" before the READY LED on the XSCFU begins to blink.

12. When adding Building Block back into config will query if want to diagnose. Select "s" to test the added BB. In below example BB#0 is used.

Do you want to start to diagnose BB#0?[s:start|c:cancel] :

13. Check the hardware diagnosis result

14. End the replacefru by hitting "c" for cancel.

15. Checking the FRU Status After Maintenance

XSCF> showstatus

XSCF> showhardconf

16. Power on all the physical partitions.

XSCF> poweron -a

Verify with

XSCF> showpparstatus -a

III. ACTIVE/COLD REPLACEMENT STEPS FOR > 1BB CONFIGURATIONS

Please see Service Manual for Active/Cold steps.

OBTAIN CUSTOMER ACCEPTANCE

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

1. Boot & check for full functionality

2. Checking the FRU Status After Maintenance

XSCF> showstatus

XSCF> showhardconf

XSCF> showpparstatus -p <ppar_id>

XSCF> showdomainstatus -p <ppar_id>

3. Have customer check the Operation Status of Physical Partitions and Logical Domains

PARTS NOTE:

None
