Exchanging the system backplane in the model 7037-A50 and 7047-185

Shows you how to restore settings before removing the system backplane.

Important: When you remove the system backplane from the model 7037-A50 or 7047-185, the system will lose its settings. In order to restore these settings or any custom settings after the backplane is replaced, if possible, do the following before you remove the system backplane:
  1. If you have not done so, verify that the backplane is the failing part.
  2. Check and record the server firmware level prior to replacing this part. Refer to Server firmware fixes.
  3. Check and record the settings you previously set using the System Management Services (SMS). Refer to Starting the System Management Services for information about setting up the SMS menus, and Using the System Management Services for information about using the SMS.

To exchange the system backplane, perform the following procedure:

  1. If you are removing the system backplane as part of another procedure, continue to the next step.
  2. Perform the following to prepare the system:
    1. Ensure that the customer has taken appropriate actions to remove the system from normal use.
    2. Power off the system.
    3. Disconnect the power source from the system.
      Note: This system might be equipped with a second power supply. Before continuing with this procedure, ensure that the power source to the system has been completely disconnected.
    4. Attach a wrist strap to a metal surface of your hardware to prevent electrostatic discharge from damaging your hardware. If you do not have a wrist strap, touch a metal surface of the system before installing or replacing hardware.
      Note: Follow the same precautions that you would use if you were not using the wrist strap. A wrist strap is for static control. It will not increase or decrease your risk of receiving electric shock when using or working on electrical equipment.
  3. Remove all of the cables from the back of the system unit.
  4. Remove the service access cover.
  5. Remove the unit air baffle. For instructions, see Model 7037-A50 and 7047-185 system unit air baffle.
  6. Lift the adapter retention bracket and remove the adapter cards. For instructions, see Prepare to remove or install Model 7037-A50 and 7047-185 adapters with the system power off.
  7. Remove the processor fan from the processor. For instructions, see Remove the model 7037-A50 and 7047-185 system unit fans.
  8. Remove all remaining cables connecting to the system backplane.
  9. Position the unit with the system backplane facing up.
  10. Slide the planar locking lever to unlock the system backplane.

  11. Lift the back of the system backplane, farthest from the planar locking lever, and slide it up and out of the system. Double check to ensure that cables are not in the way.
  12. Remove the memory from the system backplane. Keep track of the location of each memory stick, each needs to be placed in the same position on the new system backplane.
  13. To insert a system backplane, reverse the steps in this procedure.
  14. If you replaced the system backplane as part of another procedure, return to that procedure now. If you replaced it because it was not operational, verify that the new resource is functional. See Verifying the repair.
  15. Restore the settings using the System Management Services. For instructions, see Using the System Management Services.
    Note: The first time the system is powered on with the new backplane installed, system firmware progress codes will be seen. Depending on the system configuration different system progress codes will be seen. Use the system progress code information to determine the appropriate action to take.
