ESD Caution:


    

  • Circuit boards and drives contain electronic components that are  extremely sensitive to static electricity. Ordinary amounts of static electricity from clothing or the work environment can destroy the components located on these boards. Do not touch the components along their connector edges.
    • 

  • Use a Antistatic Wrist strap. Attach one end of the strap to your wrist and the other end to the chassis, depending on what type of strap you use, with the adhesive end or the metal plug.
    • 

  • Use an Antistatic Mat. Place ESD-sensitive components such as motherboards, memory, and other PCBs on an antistatic mat.
    • 





 




Contamination Caution:


    

  • Dust particles of packaging material are number one cause of datacenter contamination. Make sure to remove all packaging material, up to the ESD safe packaging material, while still being outside the datacenter.

WHAT SKILLS DOES THE ENGINEER NEED: M8-8 / M7-8 / M7-16 Product Training/Experience


TASK COMPLEXITY: 3


TIME ESTIMATE: 120 minutes


COLD replacement


FIELD ENGINEER INSTRUCTIONS


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


Physical Domains must be shut down. Server must be powered off.  


WHAT ACTION DOES THE ENGINEER NEED TO TAKE:


 


Determine which fan cable assembly requires service


1. Use one of these Oracle ILOM commands to display faulty components:


    

  1.  -> show faulty
    2. 

  2.  -> show /System/Open_Problems
    3. 

  3.  faultmgmtsp> fmadm faulty
    4. 



 


Power off the server and switch off the appropriate PDU circuit breakers


1. Power down the server (requires Oracle ILOM Reset and Host Control (r) user role)


    

  1. -> stop /System
    2. 

  2. Stopping the server can take some time, and you must wait until the following message appears on the host(s) console before proceeding to the next step.
    -> SP NOTICE: Host is off
    3. 



2. Remove power using the circuit breakers on the appopriate PDU. Turn breakers off in the following sequence :

      3. 

    3. R6, R7, R8, L2, L1, L0
      4. 

    3. 



where R indicates the right PDU from the rear of the server, L indicates the left PDU from the rear of the server, and the number represents the PDU group number.


Caution - Because standby power is always present in the server, you must switch off the circuit breakers on the PDUs before accessing any cold-serviceable components.

2. As soon as PDU circuit breakers are switched on, standby power is applied, and the SP boots.


 


 Return the faulted component to Oracle.


    

  1. If the replacement included safety covers on the connectors, install the covers on the component that you are
    2. 

  2. In the shipping container that contained the replacement component:
      

    1. Using the same material used to pack the replacement component, position the component so that it is not free to move.
      2. 

    2. Add any required paperwork or other documentation in the container.
      3. 

    3. Except when packing CMIOUs, include any tools that were loaned to you by Oracle. Do not place tools inside a container that is being used to return a CMIOU.
      4. 

    3. 

  3. Close the shipping container and seal it with the packaging tape supplied by Oracle.
    4. 

  4. Apply the shipping label to the shipping container.
    5. 

  5. Notify Oracle or an authorized shipper that the carton container is ready for pickup.
    6. 



 


OBTAIN CUSTOMER ACCEPTANCE


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


1. When SP ILOM is available, verify that there is no faulty components


    

  1. -> show faulty
    2. 

  2.  -> show /System/Open_Problems
    3. 

  3.  faultmgmtsp> fmadm faulty
    4. 



2. Start the server by running the ILOM command "start /System" (requires Oracle ILOM Reset and Host Control (r) user role).
