Step 5
Complete the following fields for each external device wired to the ONS 15454 backplane:
• Enabled—Check the check box to activate the fields for the alarm input number.
• Alarm Type—Choose an alarm type from the drop-down list.
• Severity—Choose a severity from the drop-down list.
The severity you choose determines the external alarm’s severity in the Alarms and History tabs and

activate the LEDs. Not Alarmed (NA) and Not Reported (NR) do not activate LEDs, but do report
the information in CTC.
• Virtual Wire—Choose the virtual wire number in the drop-down list to assign the external device to
a virtual wire. Otherwise, do not change the None default. For information about the AIC virtual
wire, see the Cisco ONS 15454 Reference Manual.
• Raised When—From the drop-down list, choose the contact condition (open or closed) that triggers
the alarm.
• Description—A default description is provided; enter a different description if needed.
Step 6 To provision up to four virtual wire inputs for external devices, complete Step 5 for each additional
device.
Step 7 Click Apply.
Step 8 If you are provisioning external control outputs for external devices, click the External Controls subtab.
Step 9 Complete the following options for each external control wired to the ONS 15454 backplane:
• Enabled—Check this check box to activate the fields for the alarm input number.
• Control Type—Choose the control type from the drop-down list: air conditioner, engine, fan,
generator, heat, light, sprinkler, or miscellaneous.
