3.2.2AM-3000M Hardware Installation Overview
The following illustration shows an overview of how the AM-987 and AM-174 are
mounted on the AM-140 CPU board.
Note that the AM-987 has two plastic standoffs mounted on the component side
near
the X-Bus connectors. These standoffs are simply used as nuts to hold the attaching
plastic screws in place. The heads of the plastic screws will act as thin spacers between
the AM-987’s solder side, and the empty memory connectors on the AM-140 CPU
board. This then allows the AM-987 to rest on the AM-140’s memory connectors and
give support and stabilization to the board when the added weight of the X-Bus cables
are installed.
Also note that the AM-987 has an additional CPU socket mounted between its
permanent header and the AM-140’s CPU socket. The additional socket is used to
provide the proper clearance over the AM-140 CPU components.
The AM-174 Roadrunner mounting bracket is installed by first removing four of the
AM-140 mounting screws (refer to AM-140 Preparation Illustration for screw locations).
The mounting bracket has four 1-inch hollow standoffs attached to it. The standoffs are
positioned over the vacated mounting holes on top of the CPU board and secured by
four 1.5 inch long screws.
Once the AM-987 and the Roadrunner mounting bracket are installed, all that remains is
to mount the AM-174 board to the mounting bracket and connect the two X-Bus cables
between the AM-987 and the AM-174 boards!
