Corrective Action

Critical

Internal temperature is too high for normal operation.

Mediant 9000: Temperature threshold of CPU has been exceeded. The threshold is configured by the ini file parameter [HighTemperatureThreshold]. The default is 70°C (158°F).

Mediant 9000 Rev. B, Mediant 9030 and Mediant 9080: Temperature threshold at a specific sensor(s) has been exceeded. The threshold is configured by the ini file parameter [HighTemperatureThreshold]. For example, if the temperature threshold is exceeded at sensor 1, the alarm is sent ("Board Temperature Alarm:  Sensor #1 is 88 degrees Celsius. Exceeded threshold of 70"). If the temperature threshold at sensor 2 is then exceeded as well, the first alarm is cleared and a new alarm is sent indicating exceeded temperature at both sensors ("Board Temperature Alarm:  Sensors #1,#2 are 88,90 degrees Celsius. Exceeded threshold of 70").

Mediant 4000: At least one temperature sensor detects temperature increase to critical threshold minus 5 (or greater).

"Board temperature too high"

Mediant 9000 Rev. B, Mediant 9030 and Mediant 9080:

"Board Temperature Alarm:  Sensors <#,#> <is or are> <temperature,temperature> degrees Celsius. Exceeded threshold of <threshold>"
1. Check that the ambient environment around the chassis was not changed (room temperature, air-conditioner, and location of the chassis on the site). If the ambient environment is the same, make sure that all unoccupied module slots are covered with blank panels.
2. Check the chassis ventilation outlet and make sure that they are not obstructed for air flow.

Check if you also received a Fan Tray alarm, which indicates that one or more fans in the Fan Tray are faulty (major).  If this is the case, send the faulty Fan Tray to AudioCodes as RMA.

Cleared

Temperature returns to normal operating values.

Mediant 9000 Rev. B, Mediant 9030 and Mediant 9080: All sensors detect normal temperature.

Mediant 4000: All sensors detect temperature reduced to below critical threshold minus 5 degrees for at least 60 seconds.
