Revision 2.4     
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. 
5.3.10.11  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.
