15.14.1 Alarm Contact Connections
Note The AIC-I requires a shelf assembly running Software Release 3.4.0 or later. The backplane of the ANSI
shelf contains a wire-wrap field with pin assignment according to the layout in Figure 1-21 on page 1-54.
The shelf assembly might be an existing shelf that has been upgraded to R3.4 or later. In this case the
backplane pin labeling appears as indicated in Figure 15-42 on page 15-45, but you must use the pin
assignments provided by the AIC-I as shown in Figure 1-21 on page 1-54.
