The Sensor Initialization Agent is not a logical device, but a collection of functions and services specific to handling SDR
information. The Sensor Initialization Agent works directly with the content of SDRs, in particular, with the sensor data
records and the device locator records.
The agent uses the SDR information for sensor and IPMB device initialization during system startup. The agent interprets sensor
data records and is directed by the init required fields to load thresholds to sensors that have the threshold initialization
required bit set in the SDR records. Other bits in the record direct the agent to enable sensors and devices that come up
with sensors, events, or both disabled.
The agent function runs at system power-up and at any system hard resets. We recommend that you run the agent function when
the BMC first receives standby power.
In systems that implement power management, the system management software takes additional steps to restore intermediate
settings after the system has powered up.
