INTELLIGENT PLATFORM MANAGEMENT INTERFACE
7-8 PP 41x/03x
7.4.4 Sensor Commands
The list of sensors fitted to this board, together with the sensor number and type information found
in their SDRs, is provided in Table 7-2. These sensors are scanned by the IPMI subsystem at a
rate of approximately 10 Hz. The values returned by the Get Sensor Reading command are the
values obtained in the most recent scan.
The IPMI subsystem will also include SDRs for IPMB Management Controller Locator and IPMB
Management Controller Confirmation. These records provide status information indicating the
capability of the board depending on its position in the CompactPCI chassis. They are used
primarily by other IPMB devices which want to retrieve information about the other devices on the
IPMB bus.
