12. 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.
12.1 HSC Backplane Temperature Sensor
There is a thermal sensor on the Hot Swap Backplane to measure the ambient temperature.
