4.4.4 Power Supply Temperature Sensors
The BMC monitors one or two power supply temperature sensors for each installed PMBus*-compliant power supply.
Table 26: Power Supply Temperature Sensors Typical Characteristics
Byte Field Description
11 Sensor Type 01h = Temperature
12 Sensor Number 5Ch = Power Supply 1 Temperature
5Dh = Power Supply 2 Temperature
13 Event Direction and
Event Type [7] Event direction
0b = Assertion Event
1b = Deassertion Event
[6:0] Event Type = 01h (Threshold)
14 Event Data 1 [7:6] – 01b = Trigger reading in Event Data 2
[5:4] – 01b = Trigger threshold in Event Data 3
[3:0] – Event Trigger Offset as described in Table 27
15 Event Data 2 Reading that triggered event
16 Event Data 3 Threshold value that triggered event
The following table describes the severity of each of the event triggers for both assertion and deassertion.

Hex Description
07h Upper non-critical
going high Degraded OK An upper non-critical or
critical temperature
threshold has been
crossed. 1. Check for clear and unobstructed airflow into and out of the chassis.
2. Ensure SDR is programmed and correct chassis has been selected.
3. Ensure there are no fan failures.
4. Ensure the air used to cool the system is within the thermal
specifications for the system (typically below 35°C).
