Failure to clear the TEMP_OVER alarm from the SCC board on OSN 8800

1. Run the :cfg-get-scc-temperature:bid command to query the actual temperature of the board. The query result is 22.3?C, which is within the normal range.
2. Run the alm-del-curdata:num command to delete the alarm from the NE. The alarm is generated again.
3. Perform a cold reset on the active and standby SCC boards. The alarm persists.
4. Suspect that the SCC board hardware is faulty and replace the SCC board in slot 18. After the board replacement, the alarm persists and the alarm generation time is the initial alarm generation time.
5. Remove both the active and standby SCC boards and then re-insert them respectively. The fault symptom persists.
6. Run the :alm-get-bdalm-new command to query the boards one by one and then determine that the SCC board in slot 118 reports the TEMP_OVER alarm.
