2.2.2Installing the AM-987 Board
With the AC power cord unplugged and the top cover removed, the components inside
your computer are vulnerable to damage caused by static discharge. Your body and
clothing are capable of storing an electrical charge that can damage or destroy
unprotected electronic components. Prior to handling any computer hardware, be sure
you and your work area are properly protected against static discharge. There are a
number of commercially available static protection devices designed specifically to
protect your equipment from harmful static discharge.
1.Remove the Eagle chassis cover by removing the four screws located
along the rear side edges of the cover, then lifting the rear of the cover up
and sliding it back.
2.Next, the 68030 CPU chip must be removed from its socket (U30) on the
AM-137. To remove the chip, gently pry the chip loose using a small flat
blade screw driver. Work around the chip lifting from corner to corner and
side to side until the chip pops loose from the socket. Don’t rush this
operation, if too much force is used you could break some of the pins or
the ceramic case on the CPU chip.
3.At this point, your AM-987 board should be ready to install. The AM-987
board sits on top of the AM-137 board, plugging into the vacated CPU
socket at U30. You will notice there is an extra CPU socket installed on the
bottom of the AM-987 board. The socket serves two purposes: it adds
extra height to the AM-987 board so it will not make contact with
components on the CPU board; it also protects the pins on the AM-987
board. If a pin does break, you want it to be a pin on the inexpensive
socket, not one of the pins on the AM-987 board!
Refer to the following illustration for proper placement of the AM-987 board
on the main CPU board. There is a cutout on the AM-987 board that
makes it easy to align the board with the CPU socket on the main CPU
board. Remove the protective foam from the socket on the bottom of the
AM-987, making sure no foam residue remains. Place the AM-987 board
into position, using the cutout to align the pins with the socket. If everything
is properly aligned, you will feel the board settle into position in the socket.
This is another operation where it is best to take your time and be sure the
AM-987 and the CPU socket are properly aligned. When you’re sure the
AM-987 board is in position, gently press the AM-987 board into the socket.
When installing the AM-987 board, make sure all the pins are properly
aligned. If you plug the board in incorrectly, it is possible to short power to
ground, resulting in possible damage to the AM-987 or AM-137 boards.
