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.

DISPATCH INSTRUCTIONS


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


TASK COMPLEXITY: 3


TIME ESTIMATE: 90 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 Internal Interconnect assembly requires service

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

     -> show faulty
     -> show /System/Open_Problems
     faultmgmtsp> fmadm faulty


 


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 appropriate PDU. Turn breakers off in the following sequence :


    

  1. For a SPARC M8-8 / M7-8 server :
      

    1. Bottom chassis in rack
        

      1. R8, R7, R6
        2. 

      2. L2, L1, L0
        3. 

      2. 

    2. Middle chassis in rack
        

      1. R5, R4, R3
        2. 

      2. L5, L4, L3
        3. 

      3. 

    3. Top chassis in rack
        

      1. R2, R1, R0
        2. 

      2. L8, L7,L6
        3. 

      4. 

    2. 



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.


 3. Locate the Internal Interconnect assembly at the front of the server


 


Remove the Internal Interconnect Assembly


1. Label the internal interconnect assembly slots and assemblies




If you are removing one or more internal interconnect assemblies and will return them to the
server (for example, because you are removing them to gain access to other components), you
must return them to their original locations in the server. Take care to properly label each slot
and assembly to ensure that it is properly reinstalled.




2. From the rear of the server, unseat all CMIOUs from the impacted chassis


    

  1. Check M8-8 / M7-8 / M7-16 - How to replace a Faulty CMIOU in a CMIOU chassis (Doc ID 1951961.1) for details
    2. 



3. From the front of the server, remove the internal interconnect assembly.


    

  1. Loosen the screws on the assembly. These are captive screws and will be retained in the Internal Interconnect Assembly FRU. 
    2. 

  2. When unscrewed, the top screw for each chassis will pop out, and when pushed in will open a latch to free the Internal Interconnect Assembly from the CMIOU chassis.
    3. 

  3. When the spring-loaded latch springs out, press on the screw to unlatch the assembly from the chassis. This is the top screw/latch.
    4. 

  4. Grasp the assembly and slide it out of the chassis
    5. 



 


Install an Internal Interconnect Assembly


1. From the front of the server, carefully slide the internal interconnect assembly into the chassis


Caution - The small connector pins on the back of the assembly are susceptible to damage. It is important that you align the assembly in the chassis and install the assembly slowly to avoid bending or otherwise damaging them.


2. Tighten the captive screws on the face of the assembly to secure the internal interconnect assembly to the chassis.


3. From the rear of the server, reseat all CMIOUs from the impacted chassis


    

  1. Check M8-8 / M7-8 / M7-16 - How to replace a Faulty CMIOU in a CMIOU chassis (Doc ID 1951961.1) for details
    2. 



 


Switch on the appropriate PDU circuit breakers and power on the server


1. Switch on PDU Circuit Breakers. Turn breakers on in the following sequence.


    

  1. For a SPARC M8-8 / M7-8 server:
      

    1. Bottom chassis in rack
        

      1. R8, R7, R6
        2. 

      2. L2, L1, L0
        3. 

      2. 

    2. Middle chassis in rack
        

      1. R5, R4, R3
        2. 

      2. L5, L4, L3
        3. 

      3. 

    3. Top chassis in rack
        

      1. R2, R1, R0
        2. 

      2. L8, L7,L6
        3. 

      4. 

    2. 



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.


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).
