Replacing the system backplane in the 9028-21B system

To replace the system backplane, complete the steps in this procedure.

1. Ensure that you have the electrostatic discharge (ESD) wrist strap on and that the ESD clip is plugged into a ground jack or connected to an unpainted metal surface. If not, do so now.
2. Install the system backplane in the system.
   1. Tilt the front of the system backplane about 3 inches higher than the rear of the system backplane.
   2. Install the system backplane at an angle, ensuring that the system backplane does not touch the overhanging edges of the power supply cage.
   3. Align the system backplane with the alignment pin at the rear of the chassis. Then, lower the rear of the system backplane onto the alignment pin.
   4. Lower the front of the system backplane into the chassis.
      Review the following animation for a demonstration of how to install the system backplane in the system.

3. Tighten the 11 screws that secure the system backplane to the chassis. Continue with the two screws that secure the system backplane to the power supply cage. If available, use a magnetic-tipped screwdriver.

   

4. Remove the blue plastic tab from the time-of-day battery.
5. To install the drive backplane, complete the following steps:
   1. Lower the drive backplane into the chassis.
   2. Replace the two screws that secure the drive backplane to the side wall of the chassis.
   3. Replace the screw that secures the drive backplane to the inside of the chassis.

10. If you have a stand-alone system, complete the following steps to install the system chassis into the stand-alone system enclosure.
    1. At the front of the system, lower the handle and push the system chassis into the stand-alone system enclosure until it stops.
    2. Tighten the captive thumbscrew located above the rectangular opening between the system chassis and the RDX docking station chassis.
       Review the following animation for a demonstration of how to install the system chassis into the stand-alone system enclosure.

11. Connect the control panel display cable to the system backplane.
    1. If you have a stand-alone system, feed the control panel display cable through the rectangular opening between the system chassis and the RDX docking station chassis.
    2. Connect the control panel display cable to the system backplane at physical location code Un-P0-T8.

       

12. Connect the control panel cable to the system backplane.
    1. If you have a stand-alone system, feed the control panel cable through the rectangular opening between the system chassis and the RDX docking station chassis.
    2. Connect the control panel cable to the system backplane at location Un-P0-T10.

       

13. If present, connect the internal RDX docking station power cable to the system backplane at location Un-P0-T7.

    

14. Connect the front USB cable to the system backplane.
    1. Plug the front USB cable connector to the system backplane. The physical location code for the front USB cable port is Un-P0-T5.

    

15. If you have an internal RDX docking station, feed the internal RDX docking station power cable and USB cable through the rectangular opening in the system chassis.
16. If you have a stand-alone system with an internal RDX docking station, connect the internal RDX docking station power cable and USB cable to the rear of the docking station.
    1. Connect the power cable to the RDX docking station power cable port at location Un-P2-T0.

17. Replace all the fans.
    1. Place the fan in the slot and press it firmly until the pins are locked in place.
       Review the following animation for a demonstration of how to install a fan in the system.

    2. Repeat this step for all the fans.
18. Using your labels, replace the adapters
    1. Carefully grasp the adapter by its top edge or tailstock and align the adapter with the slot.
    2. Press the adapter firmly into its connector to ensure that it is seated.
       Review the following animation for a demonstration of how to install the adapter.

    3. Repeat these steps for all the adapters

Install the system processor module and heat sink on the new system backplane.

19. Remove the socket dust cover from the system processor module socket on the new system backplane.
    1. Grasp the latches on both sides of the socket dust cover and squeeze them inwards until the latches release from the pins on the socket.
    2. Lift the cover up.

       

    3. Place the dust cover in the system processor socket on the old system backplane.
20. Place the system processor module in the system processor module socket on the new system backplane.
    1. If dust or debris is present on the system processor socket, use the supplied air pump to clean the socket. Blow small bursts of air from the center toward the sides of the socket.
    2. Hold the sides of the system processor module removal tool with system processor module and carefully lift the tool out of the system processor module tray.
    3. Lower the system processor module removal tool and system processor module onto the socket. Align the tool with the socket. Align the guide pins of the socket with the alignment holes on each side of the system processor module removal tool. Use care to lower the system processor module removal tool evenly without tilting the tool.
       Note: Do not attempt to slide the system processor module removal tool or the system processor module in any direction while the system processor module is touching the socket. If the tool and the system processor module are not aligned with the guide pins, lift the tool and the system processor module and reposition them.

       

    4. Open the latches that hold the system processor module in the removal tool. Push down on the top ring while pressing in on the tabs.
    5. Lift the system processor module removal tool off the system processor module.
       Ensure that the system processor module is properly seated in the socket. The module corners should not overlap the socket edges.
21. Inspect the TIM for visible signs of damage, such as folds or creases.
    1. If the TIM can be reused, use that TIM.
    2. If the TIM is damaged, use a new TIM.
       Note: The TIM must remain flat. Small wrinkles are acceptable, but folds are not acceptable.

       

    3. Using the tweezers, pick up each TIM and center one onto each of the two system processor modules.
       The TIM has no preferred up side. The TIM can be placed on the system processor module and centered.

       

22. Place the heat sink on the TIM. Align the heat sink with the socket. Align the guide pins on the socket with the alignment holes in the heat sink.

    

23. Secure the TIM and heat sink to the socket of the system processor module.
    1. Ensure that the heat sink load arms are fully engaged with the heat sink so that they do not slip away from the heat sink.
    2. Tighten the center load screw clockwise using the supplied hex key until a firm stop is reached. If the heat sink moves noticeably, the load arms are not engaged. Unscrew the center load screw and repeat this step.

       

24. Push the TPM card into place until it is fully seated.
    Review the following animation for a demonstration of how to install the trusted platform module card.

25. Replace all the memory. Using your notes, place the memory modules and memory fillers into the proper memory locations.
    1. Push the plastic retention clips outward to open up the slots for the memory modules.
    2. Using the alignment slots, press the memory module straight down firmly into the connector until the retention clips automatically click into place.
       Attention: Memory modules are keyed to prevent a memory module from being installed incorrectly. Note the location of the key tab within the memory module connector before you attempt to install the memory module.
       Review the following animation for a demonstration of how to install a memory module.

    3. Repeat these steps for each memory location.
