ATCA-9305 User’s Manual

Event-generating sensors with a Threshold Event/Reading Type (0x01) initiate an event mes-
sage when a sensor reading crosses the defined threshold. The default thresholds for a par-
ticular sensor are retrieved by sending the IPMC a Get Sensor Thresholds command. The 
system management controller must send the IPMC a Get Sensor Reading command to 
retrieve the current sensor reading. Refer to the IPMI specification listed in 

 for com-

plete details on using these commands.

The IPMC stores Field Replaceable Unit (FRU) information in its boot memory (SROM). The 
data structure contains information such as the product name, part number, serial number, 
manufacturing date, and E-keying information. Refer to the IPMI specification for complete 
details on the FRU data structure.
