Chapter 16 Alarm and TCA Monitoring and Management
Tip Double-click an alarm in the History window to display the corresponding view. For example,
double-clicking a card alarm takes you to card view. In network view, double-clicking a node alarm takes
you to node view (single-shelf mode) or shelf view (multishelf mode).
If you check the History window Alarms check box, you display the node history of alarms. If you check
the Events check box, you display the node history of Not Alarmed and transient events (conditions). If
you check both check boxes, you retrieve node history for both.

specific to the view where it is shown (that is, network history in the network view, node history in the
node view (single-shelf mode) or shelf view (multishelf mode), and card history in the card view).
