4.3.3 Discrete sensors

4.3.3.1 IPMC Device Locator

Each IPMC provides a PICMG compliant FRU device locator for the subsystem. This

record is used to hold location and type information of the IPMC.

4.3.3.2 Mezzanine Module Device Locator

The FRU device locator for each Add-In card is also placed in the front board sensor

data repository.

4.3.3.3 FRU Hotswap Sensor (Front blade)

Each IPMC contains a PICMG compliant Hot Swap sensor inside it’s sensor data

repository.

4.3.3.4 Version Change Sensor

A Version Change sensor is supported according to the IPMI specification.

4.3.3.5 BMC Watchdog Sensor

The BMC Watchdog sensor is supported according to the Watchdog 2 sensor type

listed in the IPMI specification.

4.3.3.6 FW Progress Sensor

The IPMC SDR contains a FW Progress sensor in order to support logging of the OS

boot process. The IPMC supports adding and forwarding of SEL entries from the

BIOS/OS system firmware progress events by sending ‘Add sel entry’ commands with

the matching sensor type to the IPMC through the KCS interface.

4.3.3.7 Therm Trip Sensor

The IPMC contains a sensor to monitor the CPU Therm Trip state through the FPGA

on each subsystem. The sensor is implemented as a discrete OEM sensor. The

single bits can be seen in following table.
