3.0 Product Disassembly Process
3.1 List the basic steps that should typically be followed to remove components and materials
requiring selective treatment:
DAUGHTER BOARD
1 Turn the three black levers that secure the daughter board to the system board to a horizontal
position to align with the slots (see Figure 2 below).
2 Remove the screw from each of the two metal retaining clips that secure the daughter board to
the metal tray (see Figure 3 below).
3 Remove two 3/16-inch hex nuts from the rear panel (see Figure 3 below).Remove the mid-plane
assembly.
4 Lift the top of the daughter board, and then pull it toward the open end of the tray until the
connectors on the back of the board are free from the metal tray.
5 Lift the daughter board out of the tray.
DAUGHTER BOARD BATTERY
1 Lay the daughter board on its top so that the components are visible.
2 Use a flat blade screwdriver to lift off the plastic cap marked “DALLAS POWERCAP”. The
battery is located in the plastic cap (see Figures 4 & 5 below).
3 Pry the battery from the plastic cap using the flat blade screwdriver.
SYSTEM BOARD
1 Using a T15 driver, remove the two remaining screws that secure the system board to the metal
tray (see Figure 6 below).
2 Slide the board forward about 12 mm (½ inch) toward the open end of the tray.
3 Lift the system board up and out of the tray.
3.2 Optional Graphic. If the disassembly process is complex, insert a graphic illustration below to
identify the items contained in the product that require selective treatment (with descriptions and
arrows identifying locations).
