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
 
 Time Estimate: 30 minutes
 
 Task Complexity: 0
 
 REMOVAL/REPLACEMENT INSTRUCTIONS:
 
 PROBLEM OVERVIEW: SPARC T8-2 Power Supply Replacement
 
 WHAT STATE SHOULD THE SYSTEM BE IN TO BE READY TO PERFORM THE RESOLUTION ACTIVITY? :


  

Note:

    

  • This is a hot service procedure that can be performed by Customers while the server is running.
    • 

  • The server's redundant power supplies support concurrent maintenance, which enables you to remove and replace a power supply without shutting down the server, provided that the other power supply is online and working.
    • 

  • 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.
    • 







  



WHAT ACTIONS ARE REQUIRED?:


  

Damage Alert: 

    

  • Perform a visual inspection of the replacement part to make sure that there are no damaged components, connectors, bent pins, damaged packages during shipping, etc. If the part is damaged, don't install it into the system, order a new part. Handle with caution and package carefully the return part to avoid any damages during shipping.

 Locate a Faulty Power Supply


 


View the following LEDs, which are lit when a power supply fault is detected:




A) Rear Power Supply Fault LED on the front bezel of the server:




Legend       LED Symbol                      Color Lights              When...


1                Service Action Required       Amber                    The power supply is faulty. Service action is required.
2                OK                                   Green                     Both DC outputs (3.3V standby and 12V main) are active and within regulation.
3                AC Present                        Green                     This LED turns on when AC voltage is applied to the power  supply.
 
B) Service Action Required LED on the faulted power supply.


  

Note: 

    

  • The front and rear panel Service Action Required LEDs are also lit when the system detects a power supply fault.
    • 




 






Remove a Power Supply


 




Caution: 

    

  • Hazardous voltages are present. To reduce the risk of electric shock and danger to personal health, follow the instructions.
    • 

  • If a power supply fails and you do not have a replacement available, to ensure proper airflow, leave the failed power supply installed in the server until you replace it with a new power supply.
    • 







 




1. Prepare for servicing.



    a. Attach an antistatic wrist strap.
    b. If necessary, release the cable management arm to access the power supplies.




2. Disconnect the power cord from the power supply that displays an amber lit Service Action Required LED.




3. Press down on the release latch to open the ejector arm.




4. Slide the power supply out of the chassis.




  

Caution: 

    

  • There is no “catch” mechanism on the power supply to prevent it from sliding completely out of the chassis. Use care when removing the power supply to prevent it from falling.
    • 

  • Whenever you remove a power supply, you should replace it with another power supply. Otherwise, the server might overheat due to improper airflow. If a new power supply is not available, leave the failed power supply installed until it can be replaced.
    • 







  
 
 
 Install a Power Supply



Caution: 

    

  • Install an A239A power supply, labeled for upright installation, in the server. The A239A power supply correctly exhausts air from the rear of the server. Do not install an A239 power supply, which might cause the server to overheat and shutdown.
    • 




  
 
 1. If necessary, release the cable management arm to access the power supplies (Do not allow the CMA to hang unsupported while it is unattached).




2. Align the power supply with the empty power supply chassis bay.




3. Slide the power supply into the bay until it is fully seated.




4. Move the release latch up to secure the power supply in place.




5. Reconnect the power cord to the power supply.




6. Verify that the AC OK LED is lit.




7. Verify that the following LEDs are not lit:




    a. Service Action Required LED on the power supply


    b. Front and rear Service Action Required LEDs


    c. Rear PS Failure LED on the bezel of the server
 
 
 OBTAIN CUSTOMER ACCEPTANCE




WHAT ACTIONS ARE REQUIRED TO RETURN THE SYSTEM TO AN OPERATIONAL STATE?:





Verify Power Supply Functionality
 
 1. Verify that the amber Service Required LED on the replaced power supply is not lit.



 2. Verify that the PS Fault LED on the front of the server is not lit.



 3. Use the Oracle ILOM "show faulty" command to verify that the fault has been cleared.




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




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