Hsc Ipmb Application And Sensors - Intel S7000FC4UR Technical Product Specification

Intel® Server System S7000FC4UR

30. HSC IPMB Application and Sensors

This section presents the additional specifications required for the HSC's implementation as an
IPMI controller. See the Intelligent Platform Management Interface Specification for more
information.
30.1 LUNs
The HSC accepts Intelligent Platform Management Bus requests directed to its LUN 00. There
are no restrictions on the LUNs that the HSC uses when sending requests or responses to other
controllers.
30.2 Sensors
The HSC implements the same basic sensor model that is utilized by the other management
controllers in the system. Sensor model information is in the Intelligent Platform Management
Interface Specification. A common set of IPMI commands configures the sensors and returns
the threshold status. The following table specifies the sensor numbers and thresholds for the
sensors implemented by the HSC.
Sensor initialization is handled as follows: The BMC implements the internal sensor initialization
agent functionality specified in the Intelligent Platform Management Interface Specification.
When the BMC initializes, it walks the sensor data records and configures the IPMB devices
that have the Init Required bit set in their SDRs. This includes setting sensor thresholds,
enabling/disabling sensor event message scanning, and enabling/disabling sensor event
messages, as indicated.
