Preparing the 9105-22A, 9105-22B, or 9786-22H system to remove and replace the system processor module

To prepare the system to remove and replace a system processor module, complete the steps in this procedure.

1. Identify the part and the system that you are working on. For instructions, see Identifying a part.
   Use the blue identify LED on the enclosure to locate the system. Ensure that the serial number of the system matches the serial number to be serviced.
2. Stop the system. For instructions, see Stopping a system.
3. Attach the electrostatic discharge (ESD) wrist strap.
   The ESD wrist strap must be connected to an unpainted metal surface until the service procedure is completed, and if applicable, until the service access cover is replaced.

   Attention:

   • Attach an electrostatic discharge (ESD) wrist strap to the front ESD jack, to the rear ESD jack, or to an unpainted metal surface of your hardware to prevent the electrostatic discharge from damaging your hardware.
   • When you use an ESD wrist strap, follow all electrical safety procedures. An ESD wrist strap is used for static control. It does not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
   • If you do not have an ESD wrist strap, just prior to removing the product from ESD packaging and installing or replacing hardware, touch an unpainted metal surface of the system for a minimum of 5 seconds. If at any point in this service process you move away from the system, it is important to again discharge yourself by touching an unpainted metal surface for at least 5 seconds before you continue with the service process.
4. If the system power is turned off, label and disconnect the power cords from the system unit.
   Note: You can use the hook-and-loop fastener to attach the power cords to the system. If you are placing the system in a service position after you disconnect the power cords, ensure that you unstrap the fastener.

   Multiple power cords. The product might be equipped with multiple AC power cords or multiple DC power cables. To remove all hazardous voltages, disconnect all power cords and power cables. (L003)
5. Label and disconnect all external cables that are attached to the PCIe adapters.
6. Loosen the front screws that secure the system unit to the rack.

   

7. Remove the hook-and-loop fasteners that secure the cable management arms and put the system in the service position.
   1. Open the side latches and pull the latches to slide the system unit fully into the service position until the slides click and hold the system unit securely. Ensure that the screws inside the latches are not secured to the rack.

   Ensure that the cable management arms can move freely. Ensure that the cables at the rear of the system do not catch or bind as you pull the system unit into the service position.

   The rack stabilizer brackets must be attached to the rack before any drawer is installed or pulled out from the rack. Do not pull out more than one drawer at a time. The rack might become unstable when more than one drawer at a time is pulled out from the rack.

   

   

8. Complete the following steps to remove the service access cover.
   Attention: Operating the system without the service access cover on for more than 5 minutes when the system power is turned on might damage the system components.
   1. Release the service access cover latch by pushing the release latch to the open position.
   2. Slide the cover off the system unit. When the front of the service access cover clears the frame ledge, lift the cover up and off the system unit.

      

9. To activate the identify LED for the faulty part, press and hold the push-button on the trusted platform module. The TPM card can be found in location P0-C22.
   Verify that the green LED on the TPM is lit, which indicates that sufficient power exists for the identify LED. If the green LED is not lit, use the location code to find the physical location by using the service label.

   

10. Locate the amber LED for the failed system processor module. Make a note of which location is illuminated, indicating the system processor module to replace.
    The physical location codes for the system processor modules are P0-C15 and P0-C24.

    

11. Open the air baffle by lifting the front of the air baffle and rotating it back. Use care not to touch or scratch the inside of the air baffle, you might damage the inner ESD surface. Do not detach the air baffle from the system.
