Stop. You have completed this procedure.
DLP-A19 Install Alarm Wires on the Backplane
Step 1 Using #22 or #24 AWG (0.51 mm² or 0.64 mm²) wires, wrap the alarm wires on the appropriate
wire-wrap pins according to local site practice. Figure 1-15 shows alarm pin assignments for the AIC-I
in the Release 3.4 or higher ONS 15454 backplane. Figure 1-16 on page 1-36 shows alarm pin
assignments for the AIC in a shelf for Release 3.3 and earlier.
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 1-15. The shelf
assembly may be an existing shelf that has been upgraded to 3.4. In this case the backplane pin labeling
will appear as indicated in Figure 1-16 on page 1-36. But you must use the pin assignments provided by
the AIC-I as shown in Figure 1-15.
Purpose This task installs alarm wires on the backplane so that you can provision
external (environmental) alarms and controls with the AIC or AIC-I card.
If you are using the AEP, do not perform this task.
