You can locate a component in either of the following ways:
● Locating a component based on alarms in DeviceManager: On the Alarms and Events
page of DeviceManager, view the help information and determine the ID of the
component to be replaced. Then locate the component at your site based on its ID.
● Locating a component based on the status of its Running/Alarm indicator: For details
