Event Direction and
Event Type
[7] Event direction
0b = Assertion Event
1b = Deassertion Event
[6:0] Event Type = 01h (Threshold)
[7:6] – 01b = Trigger reading in Event Data 2
[5:4] – 01b = Trigger threshold in Event Data 3
[3:0] – Event Triggers as described in Table 39
Reading that triggered event
Threshold value that triggered event
Table 39: Thermal Margin Sensors Event Triggers – Description
Upper non-critical
going high
The thermal margin has gone over its upper non-critical threshold.
Upper critical
going high
The thermal margin has gone over its upper critical threshold.
Table 40: Thermal Margin Sensors – Next Steps
Not a logged SEL event. Sensor is used for thermal management of the processor.
1. Check for clear and unobstructed airflow into and out of the chassis.
2. Ensure the SDR is programmed and correct chassis has been selected.
3. Ensure there are no fan failures.
