3. There are a ribbon cable and a number of small wires extending between the front panel and the
display connector on the main electronics board. Do not disconnect any of these wires; they are
long enough to allow you to lay the main electronics board assembly on your work surface
without having to disconnect them.
4. With the main electronics board assembly out of the way, you can access both sides of the
peripheral mounting bracket and have complete access to all six mounting positions.
5. To install a peripheral, simply slide it into one of the available mounting positions in your
chassis and install the four screws (two on each side) that hold the device in place.
6. Don’t forget to attach the appropriate power and interface cables to your new peripheral.
7. After you have completed your peripheral installation, you can reinstall the main electronics
board assembly.
The main electronics board side mounting bracket is an integral part of the chassis assembly.
With the bracket removed, the chassis may shift slightly, either forward or backward. In order to
reinstall the main electronics board mounting assembly, you can realign the chassis by placing
one hand on the top of the chassis and applying pressure either forward or backward. With the
chassis properly aligned, the board and its mounting assembly will slide into place.
X-Bus Cable Routing
When unfastening the main electronics board side mounting bracket, the X-Bus cables should be long
enough to allow you to lay the board assembly down flat on the side of the chassis and out of the way.
If, however, an X-Bus cable should come unplugged from either the AM-319 board or the Roadrunner
board, it is extremely important that the cables are plugged back in correctly. If the cables are not correct
the system will not boot or run self-test and the Roadrunner board could be seriously damaged!
If necessary, refer to the following cabling diagram for the correct orientation of the X-Bus cable
connections.
The top two diagrams show connections for Rev. C00 and later AM-319-00 boards. On earlier
versions of the boards, while the cables connected to the same physical locations, the labels on
the board were reversed.
