6.3 Thermal Management Parameters
The SFAPP card supports thermal monitoring to protect the temperature-sensitive hardware components. The processor on the SFAPP 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 SFAPP 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 SFAPP card. If the temperature continues to increase and exceeds a second thermal threshold (Temperature Level 2), a critical alarm is raised against the SFAPP 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. The following table 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 SFAPP card and
the SFAPP card resumes traffic processing. These thermal thresholds
(Temperature Level 1 and Temperature Level 2) are user-configurable using the
chg-thm-alm command.

| Temperature abated (cooling below Temp Level 1) | Major alarm UAM 0078 cleared | 0079 Card temperature again at nominal level |
