3.0 Product Disassembly Process

3.1 List the basic steps that should typically be followed to remove components and materials

requiring selective treatment:

SYSTEM BOARD

1 Remove the access panel:

a) Remove the two screws that secure the access panel to the computer chassis.

b) Slide the access panel back about 6 mm (1/4 inch), then rotate the top of the panel

away from the chassis (pivot on the bottom) and lift it off the unit

2 Remove the front bezel (see Figure 1 below):

a) Pull outward on all three tabs on the left side of the bezel (1)

b) Rotate the bezel off the chassis (2), beginning with the left side then the right side.

3 Disconnect the power, and data cables from the back of all installed drives.

4 Disconnect all cables from the system board.

5 Remove the heatsink from the system board (see Figure 2 below):

a) Disconnect the heatsink control cable from the system board.

b) Loosen the four captive screws that secure the heatsink to the system board.

c) Lift the heatsink from atop the processor and set it on its side to keep from

contaminating the work area with thermal grease.

6 Remove the six screws that secure the system board to the chassis (1)

(see Figure 3 below):

7 Slide the system board towards the front of the chassis (2) then remove it (3)

(see Figure 3 below).

NOTE: The system board in the computer may look slightly different from the one shown

chassis.

2 To remove the cover from the power supply (see Figures 5 & 6 below):

a) Using a phillips screwdriver, remove the six screws that secure the cover to the power

supply chassis.

b) Using dikes, cut the plastic cable clamp that secures the cables to the chassis.

c) Lift the cover off the power supply.

3 To remove the power supply PCA:

a) Cut the plastic cable clamp that secures the cables to the chassis

(see Figure 7 below).

b) Remove the four screws that secure the power supply PCA to the chassis
