FRU information includes board serial number, part number, name, asset tag, and other
information. FRUs that contain a management controller, use the controller to provide access to
the FRU information. FRUs that lack a management controller can make their FRU information
available via a SEEPROM directly connected to the mBMC’s sensor device private I
2
C bus. This
allows the system integrator to provide a chassis FRU device without having to implement a
management controller. This information can only be accessed via IPMI Master Write-Read
commands.
The mBMC implements the interface for logical FRU inventory devices as specified in the
Intelligent Platform Management Interface Specification, v1.5.
This functionality provides
commands used for accessing and managing the FRU inventory information associated with the
baseboard (FRU ID 0)
.
These commands can be delivered via all interfaces. All other FRUs
must be accessed using IPMI Master Write-Read commands.
6.3.5.1
mBMC FRU Inventory Area Format
The mBMC FRU inventory area format follows the Platform Management FRU Information
Storage Definition. Refer to
Platform Management FRU Information Storage Definition, v1.0
for
details.
The mBMC provides only low-level access to the FRU inventory area storage. It does not
validate or interpret the data stored in FRU memory. The baseboard’s FRU information is kept
in the mBMC internal flash memory.

6.4.1
Sensor Type Codes
The following section list the sensor identification numbers and information regarding the sensor
type, name, supported thresholds, assertion and deassertion information, and a brief description
of the sensor purpose. Refer to the
Intelligent Platform Management Interface Specification,
v1.5
, for sensor and event/reading-type table information.
Sensor Type
The Sensor Type references the values enumerated in the
Sensor Type Codes
table in
the IPMI specification. It provides the context in which to interpret the sensor, e.g., the
physical entity or characteristic that is represented by this sensor.
Event/Reading Type
The Event/Reading Type references values from the
Event/Reading Type Code Ranges
and
Generic Event/Reading Type Codes
tables in the
Intelligent Platform Management
Interface Specification, v1.5
. Note that digital sensors are a specific type of discrete
sensors, which have only two states.
Event Offset/Triggers
Event Thresholds are ‘supported event generating thresholds’ for threshold types of
sensors.
