the BMC monitors the sensors and uses this data as an input to the fan speed control. The
BMC instantiates an IPMI temperature sensor for each device on the baseboard.

Memory VRD-Hot Sensor(s)
The BMC monitors memory VRD_HOT# signals. The memory VRD_HOT# signals are routed to
the respective processor MEMHOT# inputs in order to throttle the associated memory to
effectively lower the temperature of the VRD feeding that memory.
For Intel® Server Systems supporting the Intel® Xeon® processor E5-2600 v3 and v4 product
families there are two memory VRD_HOT# signals per CPU slot. The BMC instantiates one
discrete IPMI sensor for each memory VRD_HOT# signal.
5.3.10.12
Add-in Module Thermal Monitoring
Some boards have dedicated slots for an IO module and/or a SAS module. For boards that
support these slots, the BMC instantiates an IPMI temperature sensor for each slot. The
modules themselves may or may not provide a physical thermal sensor (a TMP75 device). If
the BMC detects that a module is installed, it will attempt to access the physical thermal
sensor and, if found, enable the associated IPMI temperature sensor.
5.3.10.13
Processor ThermTrip
When a Processor ThermTrip occurs, the system hardware will automatically power down the
server. If the BMC detects that a ThermTrip occurs, it will set the ThermTrip offset for the
applicable processor status sensor.
5.3.10.14
Server South Bridge (SSB) ThermTrip Monitoring
The BMC supports SSB ThermTrip monitoring that is instantiated as an IPMI discrete sensor.
When an SSB ThermTrip occurs, the system hardware will automatically power down the
server and the BMC will assert the sensor offset and log an event.
5.3.10.15
DIMM ThermTrip Monitoring
The BMC supports DIMM ThermTrip monitoring that is instantiated as one aggregate IPMI
discrete sensor per CPU. When a DIMM ThermTrip occurs, the system hardware will
automatically power down the server and the BMC will assert the sensor offset and log an
event.
This is a manual re-arm sensor that is rearmed on system resets and power-on (AC or DC
power-on transitions).
5.3.11
Processor Sensors
The BMC provides IPMI sensors for processors and associated components, such as voltage
regulators and fans. The sensors are implemented on a per-processor basis.
