DISPATCH INSTRUCTIONS

WHAT SKILLS DOES THE FIELD ENGINEER/ADMINISTRATOR NEED?:
Sun Fire X4150, X4250 Training

TIME ESTIMATE: 120 minutes

TASK COMPLEXITY: 3

FIELD ENGINEER/ADMINISTRATOR INSTRUCTIONS:

PROBLEM OVERVIEW: A Sun Fire X4150, X4250 Motherboard needs replacement

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

Power off the server.
Disconnect the power cord (or cords) from the power supply (or supplies).
Remove the server from the rack.
Attach an antistatic wrist strap.
Remove the top cover.

WHAT ACTION DOES ENGINEER NEED TO TAKE:

Backup the ILOM configuration from the SP web interface using a user with "aucro" roles: Select Maintenance --> Backup/Restore -> Select Backup from the Operation drop-down list -> Run

A. Write down a simple wiring diagram prior to replacement.
Step I: Remove OLD MainBoard Unit Assembly
1. Shutdown host and power off
2. Remove power cords
3. Pull out and remove server
4. Remove top cover
5. Remove Air Baffle
6. Note HBAs locations and PCIe risers SN and remove PCIe cards and 1-slot PCIe risers boards
7. Unplug PDB cable
8. Note SN and location of FD-DIMMs then remove, place in order onto ESD mat
9. Carefully unplug HDD cables
10. Remove plastic Air Flow Baffle Unit located between fan modules and MBU
11. Note location of heatsink unit and remove.
12. Carefully remove CPUs. Do not touch pins! Note SN to make sure to plug them in same location into new MBU.
14. Remove 4 screws securing MBU to bus bar.
15. Unscrew green captive screw on front of MBU assembly.
16. Take out MBU assembly from chassis. Place on ESD mat. Write down PN & SN.
17. Visually inspect old MBU and note any obvious damage.

Step II: Installation of new MainBoard Unit Assembly
1. Install CPUs in exact same location as former MBU
2. Apply thermal grease per "CPU replacement" and install CPU heatsinks
3. Place MBU tray in to the chassis
4. Secure MBU to bus bar with screws
5. Screw green captive screw on front of MBU assembly
6. Install plastic air flow baffle between fans and MBU
7. Carefully connect PDB cable to MBU
8. Carefully connect HDD cables.
9. Install all FB-DIMMs onto MBU, in same order as OLD MBU.
10. Reinstall air baffle
11. Plug in PCIe risers and corresponding PCIe cards to original location.
12. Replace top cover, push in server into rack, reconnect all cables
13. Plug in power cords.
14. Observe boot sequence : recommendation entering BIOS setup, perform a factory default on saved parameters, then reset parameters with original configuration from Step I above.
15. Restore the ILOM configuration from the SP web interface using a user with "aucro" roles: Select Maintenance --> Backup/Restore -> Select Restore from the Operation drop-down list -> Run

OBTAIN CUSTOMER ACCEPTANCE

WHAT ACTION DOES CUSTOMER NEED TO TAKE TO RETURN SYSTEM TO AN OPERATIONAL STATE:
1. Boot up server.
2. Monitor and check messages file (if Solaris or Linux) under usual load by server to check for normal CPU temperatures
3. Use fmadm/fmdump to clear previous faults affecting old MBU.
4. Connect to BUI and eventually clear any remaining faulty component, if applicable to MBU assembly
