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 ARE REQUIRED?: No special skills required, Customer Replaceable Unit (CRU) procedure


TASK COMPLEXITY: 0


TIME ESTIMATE: 15 minutes


HOT replacement


REMOVAL/REPLACEMENT INSTRUCTIONS: Power Supply Firmware update may be required during PS replacement. See Below


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


WHAT ACTIONS ARE REQUIRED?:


Important note : After replacing the Power supply, make sure that the PSU FW is up to date and update as appropriate


    

  •     This can be done by applying the PSU FW image (load -source xxx.pkg)
    • 

  •     Refer to doc 2065435.1

Removing a Power Supply


Caution – Do not remove more than one power supply at a time, to avoid system shutdown. If a power supply fails and you do not have a replacement available, leave the failed power supply installed to ensure proper airflow in the server.


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. 



2. Locate the faulty power supply by its amber Service Required LED


3. Use a grounding strap to protect the equipment from ESD damage

4. Unpack and prepare the replacement power supply :


    

  1. If there is a protective cover on the connectors, remove the cover.
    2. 

  2. Inspect the connectors for possible damage.
    3. 



5. Remove the faulty power supply from the server:


    

  1. At the front of the server, squeeze the green release latch on the power supply to be removed.
    2. 

  2. Pull the extraction lever toward you to disengage the power supply.
    3. 

  3. Slide the power supply half way out of the server.
    4. 

  4. Fold the extraction lever back toward the center of the power supply until it latches into place.
    5. 

  5. Carefully remove the power supply from the server.
    6. 



Note - A SPARC M8 server power supply contains three shims along its side to enable it to fit correctly in a power supply slot. When replacing a SPARC M8 server power supply, you must remove these three shims from the faulty power supply and install them on the replacement power supply. Otherwise, the SPARC M8 power supply will not seat correctly in the chassis slot.


 


Installing a Power Supply


1. Use a grounding strap to protect the equipment from ESD damage.


2. If you have not already done so, inspect and prepare the replacement power supply.


    

  1. Remove any protective caps from the connectors on the power supply.
    2. 

  2. Inspect the connectors for damage.
    3. 

  3. Inspect the connection at the rear of the empty slot.
    4.

3. Insert the power supply


    

  1. Open the latch on the replacement power supply.
    2. 

  2. Align the power supply and slide it into the empty bay.
    3. 



4. Secure the power supply in the chassis.


    

  1. Press on the center of the power supply grill until the lowered latch lever moves upward.
    2. 

  2. Lift the lever up and press the lever against the power supply to fully seat it in the server.
    3. 



 


WHAT ACTION IS NEEDED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE:


Verify that the fault has been cleared and the replaced component is operational


    

  1. Verify that the Power OK and AC Present LEDs are lit, and that the Fault LED and front and rear Service Required LEDs are not lit.
    2. 

  2. Verify that there is no faulty components

      

    1. -> show faulty
      2. 

    2.  -> show /System/Open_Problems
      3. 

    3.  faultmgmtsp> fmadm faulty
      4. 

    

    3. 

  3. Perform one of the following tasks based on your verification results

      

    1. If the previous steps did not clear the fault, refer to doc 1309092.1 for information about the tools and methods you can use to diagnose and clear component faults.
      2. 

    2. If the previous steps indicate that no faults have been detected, the component has been replaced successfully. No further action is required
      3. 

    

    4. 

  4. Important note : make sure that the PSU FW is the latest available and update as appropriate

      

    1. This can be done by applying the PSU FW image (load -source xxx.pkg)
      2. 

    2. Refer to doc 2065435.1
      3. 

    

    5. 



 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.
