Connect the 16-Ports Fanout Module
Cables
After setting the I/O port address, the controller memory starting address,
and the hardware interrupt request level for the board, you are ready to
connect the ribbon cables and port modular cables to the 16-Ports Fanout
module as follows.
If you have the optional AT&T IPC-1600 Ports Cabinet, locate and install
the cabinet now. Refer to Appendix C, “AT&T IPC-1600 Ports Cabinet,” and
the documentation that came with the cabinet for installation information.
After installing the cabinet, return to this procedure to “Connect the Ribbon
Cables to the IPC-1600” and “Install the Board” in the host computer.
If you DO NOT have the optional AT&T IPC-1600 Ports Cabinet, locate
the two 80-conductor ribbon cables and the 16-Ports Fanout module. Connect
the ribbon cables to the 80-pin connectors at the rear of the 16-Ports Fanout
module. The connectors on the ribbon cables are keyed for proper alignment
with the connectors at the rear of the fanout module. Make sure that the
retaining clips are properly secured.
If you DO NOT have the optional AT&T IPC-1600 Ports Cabinet, connect
the port modular cables to the 16-Ports Fanout module. When connecting the
modular cables to the 16-Ports Fanout module, it is important to label
(identify) the circuit(s). The label information should include the port
identification (tty
xyy) and the connecting device identification. Be sure to
connect the ground lead of the modular cable to the ground lug on the
16-Ports Fanout module.
