Cisco ONS 15454, Hardware Installation Manual

Page: 125 / 516

The ONS 15454 ANSI has a backplane pin field located at the bottom of the backplane. The backplane pin
field provides 0.045 inch2 (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 53: ONS 15454 ANSI Backplane Pinouts, on page 97 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.
The AIC-I requires a shelf running Software R3.4.0 or later. The backplane of the ANSI shelf contains a
wire-wrap field with pin assignment according to the layout in
Figure 52: Cisco ONS 15454 Backplane Pinouts
(Release 3.4 or Later), on page 96 . The shelf might be an existing shelf that has been upgraded to Software
R3.4 or later. In this case, the backplane pin labeling appears as indicated in Figure 53: ONS 15454 ANSI
Backplane Pinouts, on page 97 , but you must use the pin assignments provided by the AIC-I card as shown
in Figure 52: Cisco ONS 15454 Backplane Pinouts (Release 3.4 or Later), on page 96 .
