Caution Always use the supplied ESD wristband when working with a powered ONS 15454. Plug the wristband
cable into the ESD jack located on the lower-right outside edge of the shelf assembly.
The ONS 15454 has a backplane pin field located at the bottom of the backplane. The backplane pin field
provides 0.045 square inch (29 mm2) wire-wrap pins for enabling external alarms, timing input and
output, and craft interface terminals. This section describes the backplane pin field and the pin
assignments for the field. Figure 1-42 shows the wire-wrap pins on the backplane pin field. Beneath each
wire-wrap pin is a frame ground pin. Frame ground pins are labeled FG1, FG2, FG3, etc. Install the
ground shield of the cables connected to the backplane to the ground pin that corresponds to the pin field
used.
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 1-42. The shelf
assembly might be an existing shelf that has been upgraded to R3.4 or later. In this case the backplane
pin labelling appears as indicated in Figure 1-43 on page 1-66. But you must use the pin assignments
provided by the AIC-I a s shown in Figure 1-42.
