Field Replaceable Units and Sensor Data Records

Field replaceable units (FRUs) are major modules in the chassis that contain active electronic
circuitry. FRUs can store information-such as board serial number, part number, name, and asset
tag-that can be read using the System Setup Utility. The BMC stores FRU information for the
baseboard in a nonvolatile storage component on the board.
The BMC uses Sensor Data Records (SDRs) to identify the sensors in the system for monitoring.
SDRs provide a list of the sensors, their characteristics, location, type, and type-specific
information, such as default threshold values, factors for converting a sensor reading into the
appropriate units (mV, rpm, degrees Celsius), and information on the types of events that a sensor
can generate. The BMC stores SDR information in a nonvolatile storage component on the
baseboard.
You can use the FRU/SDR Load Utility to initialize or update the FRU and SDR information.
®
Intel server boards are shipped from the factory with some sensors disabled because the actual
configuration of the chassis is only determined when the user completes the system configuration.
For example, chassis-specific FRU information, such as chassis part number, must be configured
when the system is configured. For these reasons, it is important to run the FRU/SDR Load Utility
as part of the system setup process. You should also run the FRU/SDR Load Utility whenever you
change the number of fans, processors, or power supplies in the server.

System Event Log

The BMC manages a system event log (SEL), where it records significant or critical system events.
These events include temperatures and voltages out of range, fan failures, and other sensor-related
events. The BIOS, software, and other devices can also log events by sending messages to the
BMC. The SEL is stored in nonvolatile storage.
You can view the current contents of the SEL by using the System Setup Utility.

Platform Event Management

Events can trigger alerts and other actions by the BMC. The server is configured with the
following set of standard events:
Temperature sensor out of range
Voltage sensor out of range
Fan failure
Chassis intrusion
Power supply failure
Memory error
POST error
Processor fault resilient booting (FRB) failure
Fatal nonmaskable interrupt (NMI) from a source other than the front panel switch
Watchdog timer reset, power down, or power cycle
System restart (reboot)
