Sensor Monitoring
The BMC monitors system hardware and reports system health. Some of the sensors include those for
monitoring:
•
Component, board, and platform temperatures
•
Board and platform voltages
•
System fan presence and tach
•
Chassis intrusion
•
Front Panel NMI
•
Front Panel Power and System Reset Buttons
•
SMI timeout
•
Processor errors
The information gathered from physical sensors is translated into IPMI sensors as part of the IPMI Sensor
Model. The BMC also reports various system state changes by maintaining virtual sensors that are not
specifically tied to physical hardware.
Appendix B – Integrated BMC Sensor Tables
for additional sensor information.

Field Replaceable Unit (FRU) Inventory Device
The BMC implements the interface for logical FRU inventory devices as specified in the Intelligent Platform
Management Interface Specification, Version 2.0. This functionality provides commands used for accessing
and managing the FRU inventory information. These commands can be delivered through all interfaces.
The BMC provides FRU device command access to its own FRU device and to the FRU devices throughout the
server. The FRU device ID mapping is defined in the Platform Specific Information. The BMC controls the
mapping of the FRU device ID to the physical device.
6.9
System Event Log (SEL)
The BMC implements the system event log as specified in the Intelligent Platform Management Interface
Specification, Version 2.0. The SEL is accessible regardless of the system power state through the BMC's in-
band and out-of-band interfaces.
The BMC allocates 95231bytes (approx. 93 KB) of non-volatile storage space to store system events. The SEL
timestamps may not be in order. Up to 3,638 SEL records can be stored at a time. Because the SEL is circular,
any command that results in an overflow of the SEL beyond the allocated space will overwrite the oldest
entries in the SEL, while setting the overflow flag.
Events logged to the SEL can be viewed using Intel’s SELVIEW utility, Embedded Web Server, and Active
System Console.

System Fan Management
The BMC controls and monitors the system fans. Each fan is associated with a fan speed sensor that detects
fan failure and may also be associated with a fan presence sensor for hot-swap support. For redundant fan
configurations, the fan failure and presence status determines the fan redundancy sensor state.
The system fans are divided into fan domains, each of which has a separate fan speed control signal and a
