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 (refer to page 166). The BMC stores
FRU information for the mainboard in a nonvolatile storage
component on the board.
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 (refer to page 166). The BMC stores
FRU information for the mainboard 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 mainboard.

You can use the FRU/SDR load utility (refer to page 183) to initialize or
update the FRU and SDR information. Some machines 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. Chassis-specific information in
the FRU, such as chassis part number, is also absent. 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. Such events include instances of out of range
temperatures and voltages, fan failures, and other sensor-related
events. The BIOS, software, add-in cards, and other devices can also
log events by sending messages to the BMC. The SEL is stored in a
nonvolatile storage.

You can view the current contents of the SEL by using the System Setup
