ONS 15454 ANSI Alarm Expansion Panel

The optional ONS 15454 ANSI alarm expansion panel (AEP) can be used with the AIC-I card to provide an
additional 48 dry alarm contacts for the ONS 15454 ANSI: 32 inputs and 16 outputs. The AEP is a printed
circuit board assembly that is installed on the backplane. The following figure shows the AEP board; the left
connector is the input connector and the right connector is the output connector.
The AIC-I without an AEP already contains direct alarm contacts. These direct AIC-I alarm contacts are
routed through the backplane to wire-wrap pins accessible from the back of the shelf. If you install an AEP,
you cannot use the alarm contacts on the wire-wrap pins. For more information about the AIC-I, see the
"Install the Control Cards" chapter in the Cisco ONS 15454 DWDM Configuration Guide.
