Installing AM-987 Support Hardware
6.At this point, your AM-987 board should be ready to install. The AM-987
board sets on top of the AM-185 board, plugging into the vacated CPU
socket. (AM-185-00 = U97, AM-185-50 = U123). 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 two illustrations for proper placement of the AM-987
board on the main CPU board. One Illustration shows installation an
AM-185-00, and the other shows placement on an AM-185-50. 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.
