For further information about CPU modules, see your Sun Enterprise 220R Server Owner's Guide.

3.6.2 What to Do

1. Locate the appropriate slot for the CPU module that you are installing in the CPU card cage on the main logic board.

2. Align the edges of the CPU module board with the corresponding grooves in the CPU card cage.

3. Verify that the two ejection levers are open.

4. Slide the CPU module evenly into the grooves in the CPU card cage.

   Push down until the CPU module meets the connector at the bottom of the CPU card cage.

   

5. Engage the notch in each lever with its side of the CPU card cage.

6. Simultaneously push both levers toward the center of the CPU module until the CPU module seats in its connector.
