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 tabs (C) on the power supply cage. See the following figure.

      

   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 backplane catches on the tabs (A) on the power supply cage, lower the front end enough so that it clears the tabs. See the following figure.

      

   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 figure
      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 six screws (C) that attach the backplane to the sides of the system chassis. See the following figure.
      Notes:

      • You might find it helpful to use a magnetic screwdriver.
