4. With the AM-319-20 assembly out of the way, you will be able to 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 AM-319-20
assembly.
The AM-319-20 side mounting bracket is an integral part of the chassis assembly. You may
find that with the bracket removed, the chassis may shift slightly, either forward or backward.
To reinstall the AM-319-20 mounting assembly, you can realign the chassis by placing one
hand on the top of the chassis and applying pressure either forward of backward. With the
chassis properly aligned, the board and its mounting assembly will slide into place.
X-Bus Cable Routing
When unfastening the AM-319-20 side mounting bracket, you should be able to lay the board assembly
down flat on the side of the chassis and out of the way without disconnecting the X-Bus cables.
However, if an X-Bus cable should come unplugged from either the AM-176-10 or the AM-319-20 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 one or both boards could be seriously damaged!
The X-bus cables must be connected as follows:
•
C/S bus cable into P2 on the AM-176-10 board and P8 on the AM-319-20 board
•
A/D bus cable into P1 on the AM-176-10 board and P7 on the AM-319-20 board
Internal Ethernet Cable Routing
The shielded level 5 Ethernet data cable connects the Ethernet port on the AM-176-10 CPU board to the
AM-328-20 connector board mounted on the rear panel. This cable should be routed from J1 on the AM-
176-10 board to J1 on the AM-368-20 connector board.
In addition, an optional remote status LED cable supplies the output signals to the LED indicator lights
(100 Mbps, 10 Mbps, and Link). This cable should be connected between P6 on the AM-176-10 CPU
board and P1 on the AM-368-20 connector board.
