Getting Inside the Platform
Removing the Card Cage Access Panel
Use a Phillips #2 screwdriver to remove the left access panel in order to reach the
circuit card cage as follows (see Figure 2-2):
1. Place the MAP/40 on its side using one of the two methods below if you
intend to work inside the computer.
The circuit card cage area is more accessible if the tower configuration is
on its side when you work inside the computer.
a. If you have cables attached to the MAP/40 and want to leave the
computer on the floor:
i. Place two books, similar in size to large phone books, or a
similar form of support on the floor.
ii. Turn the MAP/40 on its side, resting the side of the computer
opposite from the support base on the two books. See Fig-
ure 2-3.
b. If you do not have cables attached to the MAP/40 or currently have it
placed on a table: Place the MAP/40 (tower configuration) on its
side with the support base over the edge of the table. See Figure 2-
2.
2. Loosen the flat-head 1/4 inch length screws by two turns only with the Phil-
lips screwdriver. You are to provide adequate clearance only. It is
not
nec-
essary to remove the screws.
3. Apply pressure gently with your hands, palms down on the access cover.
4. Push into the chassis with your palms and slide the access cover back
toward the chassis area.
5. Lift up and remove the cover once you have cleared the Phillips screw
heads.
