Replacing the system backplane in the 9009-41A, 9009-41G, 9009-42A, 9009-42G, 9223-42H, or 9223-42S

Follow these steps to replace the system backplane.

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 replacement system backplane.
   1. Grasp the replacement system backplane by positions (A) and (B) on the front and middle metal bulkheads and begin lowering the backplane into the chassis. As you lower the backplane, be careful not to hit the pins (C) on the power supply cage. See the following image.

      

   2. Tilt the backplane so that the front end is high and the back end is low as you continue to lower the backplane into the chassis. When the system backplane catches on the pins (A) on the power supply cage, lower the front end enough so that it clears the pins. See the following image.

      

   3. Continue lowering the backplane into the chassis until the pins engage.
   4. Place your fingers in positions (A) and (B) and slide the system backplane slightly toward the rear of the system as shown in the following image.
      Note: Slide the system backplane carefully. There is just enough space for the power connectors to clear the flange on the power supply cage (C).

      

   5. Using a Phillips screwdriver, replace and screw in the four screws (D) that are vertically aligned and that attach the backplane to the sides of the system chassis. See the following image.
      Notes:

      • You might find it helpful to use a magnetic screwdriver.
      • Do not remove the silver Torx screws.

      

   6. Using a Phillips screwdriver, replace and screw in the four screws (C) that attach the backplane to the sides of the system chassis. See the previous image.
   7. Using a Phillips screwdriver, replace and screw in the two screws (B) that attach the backplane to the power supply cage. See the previous image.
   8. Using a Phillips screwdriver, replace and screw in the three black screws (A) that mount the backplane to the chassis. See the previous image.
   9. Using a Phillips screwdriver, replace and screw in the screw that is underneath the fan socket.
3. Replace the fan socket on the right side of the bulkhead on the new system backplane as shown in the following images:
   1. Insert the socket tabs into the bulkhead.
   2. Slide the socket to the side to fasten it to the bulkhead.
   3. Ensure that the pin (A) clicks into place to secure the socket to the bulkhead.

      

      

4. Remove the socket dust covers from the system processor module sockets 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 system backplane. See the following image.
   2. Lift the socket dust cover straight up as shown in the following image. Set the dust cover aside.

      

   3. If your system has a second system processor, repeat steps 4.a through 4.b to remove the other socket dust cover.
5. Place the original system backplane on the packaging for the replacement system backplane FRU and place it near the system with the replacement system backplane.
6. Install the system processor modules from the original system backplane in the new system backplane:
   1. If dust or debris is present on the system processor socket on the new system backplane, use the supplied air pump to clean the socket before you install the new system processor. Blow small bursts of air from the center toward the sides of the socket, as shown the following image.

      

   2. If necessary, take the cover off of the system processor module tray.
   3. Hold the sides of the tool with system processor module and carefully lift the tool out of the system processor module tray.
   4. Lower the tool and system processor module onto the socket. Align the beveled corner of the tool with the beveled corner on the socket. Align the guide pins (A) with the alignment holes (B) on each side of the tool. Use care to lower the tool evenly without tilting the tool.
      Note: Do not attempt to slide the tool and 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.

      

   5. Open the latches that hold the system processor module in the supplied removal tool (A) as shown in the following figure. Push down on the ring (B) while pressing in on the tabs (C).

      

   6. Lift the tool off the system processor module.
   7. Repeat 6.a through 6.f for the other system processor module.
7. Replace the thermal interface material (TIM) and heat sinks.
   1. Using the tweezers, move the old processor's TIM from the clean, dry surface and center it onto the new system processor module.
      The TIM has no preferred up side. The TIM can be placed on the processor and centered as shown in the following figure.

      

   2. Place the heat sink on the TIM as shown in the following figure.

      

   3. Ensure that the heat sink load arms are engaged as shown by (A) in the following figure.
   4. Tighten the center load screw clockwise by using the supplied hex key as shown by (B) in the following figure 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 again.

      

   5. If your system has a second system processor module, repeat steps 7.a through 7.d to replace the other TIM and heat sink.
