Installation
Warning
Power off all units connected to your computer before you install the AMUX-64T.
If you have a 50-pin MIO board, connect a 50-pin ribbon cable from the
50-pin MIO board I/O connector to either connector J1 or J2 on the
AMUX-64T. If you have a 68-pin MIO board, connect a 68-pin shielded
or ribbon cable from the 68-pin MIO board I/O connector to J42 on the
AMUX-64T.
If you use more than one AMUX-64T, you can daisy-chain the boards by
connecting J1 or J2 on one AMUX-64T to J1 or J2 on another AMUX-64T,
and so on (see Figure 2-2).
You can install the AMUX-64T into a 19-in. rack-mount kit as shown in
Figure 2-3. If you use a round 68-pin shielded cable, route the cable as
shown, leaving passage for the ribbon cable (if you use it for
daisy-chaining) in the other direction.
