14.3.4 Viewing Alarm-Affected Circuits
A user can view which ONS 15454 circuits are affected by a specific alarm by positioning the cursor
over the alarm in the Alarm window and right-clicking. A shortcut menu appears
the user selects the Select Affected Circuits option, the Circuits window opens to show the circuits that
are affected by the alarm.
Figure 14-2
14.3.5 Conditions Tab
The Conditions window displays retrieved fault conditions. A condition is a fault or status detected by
ONS 15454 hardware or software. When a condition occurs and continues for a minimum period, CTC
raises a condition, which is a flag showing that this particular condition currently exists on the
ONS 15454.
The Conditions window shows all conditions that occur, including those that are superseded. For
instance, if a network problem causes two alarms, such as LOF and LOS, CTC shows both the LOF and
LOS conditions in this window (even though LOS supersedes LOF). Having all conditions visible can
be helpful when troubleshooting the ONS 15454. If you want to retrieve conditions that obey a
root-cause hierarchy (that is, LOS supersedes and replaces LOF), you can exclude the same root causes
by checking "Exclude Same Root Cause" check box in the window.
Fault conditions include reported alarms and Not Reported or Not Alarmed conditions. Refer to the
trouble notifications information in the Cisco ONS 15454 Troubleshooting Guide for more information
about alarm and condition classifications.
