14. Hot Swap Controller events
The Hot Swap Controller (HSC) implements the same basic sensor model that is utilized by the other management controllers in the system.
Sensor model information is contained in the document Intelligent Platform Management Interface Specification. A common set of IPMI
commands is used for configuring the sensors and returning threshold status.
14.1 HSC Backplane Temperature Sensor
There is a thermal sensor on the Hot Swap Backplane to measure the ambient temperature.

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 82
15 Event Data 2 Reading that triggered event.
16 Event Data 3 Threshold value that triggered event.
