Removing the Daughterboard from the Motherboard

WARNING

Never expose the module’s components to Electrostatic Discharge. Make sure you have attached the module’s disposable grounding strap to your wrist and always place the module on a non-conductive surface.

To remove the module’s daughterboard from the motherboard:

1.Place the module (component side up) on a non-conductive, ﬂat surface. Position the module so that the module’s front (faceplate) is to the left and the module’s back (backplane connectors) is to the right. The daughterboard abuts the backplane connectors (see Figure 2-1).

2.Locate the daughterboard’s nine securing screws (see Figure 2-9).

3.Use a phillips head screwdriver to remove the securing screws. Set the screws aside.

4.Grasp the daughterboard and lift up.

5.Turn the daughterboard over to reveal its user accessible components (see Figure 2-10).
