Power Supply Temperature Sensors

The BMC monitors one or two power supply temperature sensors for each installed PMBus*-compliant power supply.
The following table describes the severity of each of the event triggers for both assertion and deassertion.
Assertion
Event Trigger Offset
Severity
Hex Description
07h Upper non-critical Degraded
going high
09h Upper critical going non-fatal
high
Revision 1.1

Table 26: Power Supply Temperature Sensors Typical Characteristics

Byte Field
11 Sensor Type 01h = Temperature
12 Sensor Number 5Ch = Power Supply 1 Temperature
5Dh = Power Supply 2 Temperature
13 Event Direction and [7] Event direction
Event Type
[6:0] Event Type = 01h (Threshold)
[7:6] – 01b = Trigger reading in Event Data 2
14 Event Data 1
[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

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).
