Chapter 3: Monitoring

3.3.1 Default Threshold Values

NOTE:

The threshold values listed below are used to trigger a warning event and sound

the alarm. A different value set is reserved for triggering the cooling fans to

operate at a high rotation speed. The fan speed value set is not user-configurable.

Table 3-8 shows the default threshold values for the subsystem. If any of these values

are surpassed the alarm will sound:

Upper Threshold Lower Threshold

+3.3V

+3.6V +2.9V

+5V

+5.5V +4.5V

+12V

+13.2V +10.8V

CPU Temperature

90ºC 5ºC

Board Temperature

80ºC 5ºC

Enclosure Ambient

Temperature

40ºC 0ºC

Table 3-8: Default Threshold Values

The controller self-monitoring thresholds in Table 3-8 are the default threshold

values. To change these pre-set values, please refer to the Generic Operation

Manual that came with your system. The values set for the subsystem’s ambient

temperature are pre-configured before shipping and cannot be changed.

3.3.2 Failed Devices

The audible alarm will be triggered if any of the following devices fail:

• Cooling fan modules

• PSU modules

• BBU modules

• Hard drives

• Components on the RAID controller

NOTE:

If the temperature exceeds a preset threshold, the BBU charger circuits will stop

charging. You will then receive a message that says “Thermal Shutdown/Enter

Sleep Mode.” When the temperature falls back within normal range, the battery

will resume charging.
