Alarms

Refer to Unsolicited Alarm and Information Messages Reference for descriptions and corrective procedures for alarms related to EAGLE features and functions.

For descriptions of and corrective procedures for MPS-related alarms, refer to Alarms and Maintenance Guide for EAGLE Application Processor.

This section lists new Unsolicited Alarm Messages (UAMs) used to support the EAGLE ENUM Mobile Number Portability and Tier One Address Resolution feature.

Thermal Management Parameters

The ENUM card supports thermal monitoring to protect the temperature-sensitive hardware components. The processor on the ENUM card can overheat as a result of high ambient temperature or airflow blockage. If the junction temperature increases above operating limits, the CPU halts and the ENUM card shuts itself down to prevent permanent, catastrophic damage. In the event of thermal shutdown all processor activity ceases.

To minimize data loss due to overheating, a graceful shutdown is implemented to detect and alert the user to the increasing thermal conditions. When the CPU temperature rises above nominal range and exceeds a thermal threshold (Temperature Level 1), a major alarm is raised against the ENUM card. If the temperature continues to increase and exceeds a second thermal threshold (Temperature Level 2), a critical alarm is raised against the ENUM card and traffic processing is stopped. When the second thermal threshold is exceeded, the application is notified from the operating system. The state of card will transition to the IN-ANR Restricted state. Table 6-3 shows the thermal events, actions, and alarms.

After the temperature decreases below the Temperature Level 2 threshold, the raised critical alarm is cleared and the corresponding major alarm is raised. When the temperature returns to its nominal range (below Temperature Level 1), a clearing alarm will be raised for the ENUM card and the ENUM card resumes traffic processing. These thermal thresholds (Temperature Level 1 and Temperature Level 2) are user-configurable using the chg-thm-alm command.
