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 / M7-8 / M7-16 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 stopped. Server must have AC power removed.


WHAT ACTION DOES THE ENGINEER NEED TO TAKE:


Determine which SP Internal Interconnect 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 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. 

  2. For a SPARC M7-16 server:
      

    1. R4, R5, L5, L4
      2. 

    2. R0, R1, R2, L8, L7, L6
      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.


 3. Locate the SP internal interconnect assembly at the front of the server


 


Gain access to the SP internal interconnect assembly


1. From the rear of the server, remove the SPs or SPPs and the SP tray from the impacted chassis


    

  1. Check M8-8 / M7-8 / M7-16 How to replace a Faulty Service Processor (SP) in a CMIOU chassis or in a Switch chassis (Doc ID 1988106.1) for details
    2. 

  2. Check M7-16 How to replace a Faulty Service Processor Proxy (SPP) in a CMIOU chassis (Doc ID 1988126.1) for details
    3. 

  3. Check M8-8 / M7-8 / M7-16 How to replace a Faulty Service Processor Tray (SP tray) in a CMIOU chassis or in a Switch chassis (Doc ID 1988151.1) for details
    4.

    3. 



 


Remove the SP internal interconnect assembly


1. From the front of the server, remove the SP internal interconnect assembly


    

  1. Loosen the captive screws on the SP internal interconnect assembly to free it from the chassis
    2. 

  2. Remove two T-20 screws that are located inside the square holes on the white, horizontal strip that extends to the left of the SP internal interconnect assembly
    3. 

  3. Carefully slide the SP internal interconnect assembly out of the chassis
    4. 



 


Install the new SP internal interconnect assembly


1. Insert the guide pin shield to avoid damaging the connector pins on the rear of the SP internal interconnect assembly.


Refer to the Service Manual to properly place the guide pin shield.


If the SP internal interconnect you are installing has stirrup-shaped leaf springs that hold the inner and outer horizontal connectors in place, handle the interconnect with care to avoid damaging the floating connector housings. These housings can become damaged if they loosen and catch on the chassis, which can impact your ability to install or remove the interconnect. If you notice that these springs or the connectors are damaged, do not install the interconnect into the chassis.


2. From the front of the server, carefully slide the SP 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.


3. Secure the SP internal interconnect assembly to the chassis


    

  1. Tighten the captive screws on the face of the assembly
    2. 

  2. Install the T-20 screws in the white, horizontal strip that extends to the left of the SP internal interconnect assembly
    3. 



4. Remove the guide pin shield


 


Reinstall components you removed to service the assembly


1. Reinstall all of the interconnect assemblies that you removed


    

  1. Check M8-8 / M7-8 / M7-16 How to replace a Faulty Internal Interconnect Assembly (Doc ID 1991406.1) for details
    2. 

  2. Check M7-16 How to replace a Faulty External Interconnect Assembly (Doc ID 2022844.1) for details
    3. 



2. Reseat all CMIOUs or switch units 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. 

  2. Check M7-16 How to replace a Faulty Switch Unit in a Switch Chassis (Doc ID 1987712.1) for details
    3. 



3. From the rear of the server, reinstall the SP tray and the SPs or SPPs


    

  1. Check M8-8 / M7-8 / M7-16 How to replace a Faulty Service Processor (SP) in a CMIOU chassis or in a Switch chassis (Doc ID 1988106.1) for details
    2. 

  2. Check M7-16 How to replace a Faulty Service Processor Proxy (SPP) in a CMIOU chassis (Doc ID 1988126.1) for details
    3.

    4. 



 


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

      2. 

    2. R0, R1, R2, L8, L7, L6
      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.


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).
