2. Move the ejector levers on the front panel of the MPU outwards, hold up the MPU by one hand
without touching any electronic components on the MPU, and hold the front panel by the other
hand to push the MPU into the slot along the slide rails slowly.
3. Push the ejector levers inward to ensure close contact between the MPU and the backplane.
4. Position the screws into the holes and fasten them with a screwdriver to fix the MPU.
