Intel® Server Board X38ML Platform Management ƒ Default Hysteresis Hysteresis setting applies to all thresholds of the sensor. This column provides the count of hysteresis for the sensor, which can be 1 or 2 (positive or negative Hysteresis). ƒ Criticality Criticality is a classification of the severity and nature of the condition. It also controls the behavior of the Front Panel Status LED. Refer to Table 31 for more information. ƒ Standby Some sensors operate on standby power. These sensors may be accessed and/or generate events when the main (system) power is off, but AC power is present. Table 40.

Revision 1.3

Intel order number E15331-006

Default Hysteresis

Hysteresis setting applies to all thresholds of the sensor. This column provides the count of hysteresis for the sensor, which

can be 1 or 2 (positive or negative Hysteresis).

Criticality

Criticality is a classification of the severity and nature of the condition. It also controls the behavior of the Front Panel Status

LED. Refer to Table 31 for more information.

Standby

Some sensors operate on standby power. These sensors may be accessed and/or generate events when the main (system)

power is off, but AC power is present.
