    The Info tab lists the ID, Organizational Path, Affected Component, Alarm State, and Verified. Two items in the tab that do not appear for Fiber Node alarms and only appear for CMTS Outage alarms are:

    • Organizational Path: Indicates the path from the top of the Hierarchy to the CMTS.
    • Affected Component: Indicates the component that is the source of the problem. The CMTS component is displayed as a link and links to the Summary section of Analyze Network View.

      NOTE: You must have Analyze Network View permission to view the affected component details. If not, the CMTS component is displayed without the link.

  4. If there are fiber nodes associated with the CMTS outage, click the Affected FNs tab in the sub-table, for additional information about the fiber nodes.

    The tab lists all the fiber nodes involved in the Outage alarm. If there are no associated fiber nodes, the table is empty.
