Platform Management Technical Product Specification
9.3.10.6 Inlet Temperature Sensor
Each platform supports a thermal sensor for monitoring the inlet temperature. The inlet
temperature sensor is on the backplane of Intel Server Chassis with address 21h. For
®
third-party chassis, sensor 20h which is on the front edge of the baseboard can be used as
inlet temperature sensor with several degrees of preheat from front end.
9.3.10.7 Baseboard Ambient Temperature Sensor(s)
The server baseboard provides one or more physical thermal sensors for monitoring the
ambient temperature of a board location. This is typically to provide rudimentary thermal
monitoring of components that lack internal thermal sensors.
9.3.10.8 Chpiset Thermal Monitoring
The BMC monitors the chipset temperature. This is instantiated as an analog (threshold) IPMI
thermal sensor.
9.3.10.9 Exit Air Temperature Monitoring
This sensor is only available in Intel ® Server Chassis. The BMC synthesizes a virtual sensor to
approximate system exit air temperature for use in fan control. This is calculated based on the
total power being consumed by the system and the total volumetric air flow provided by the
system fans. Each system shall be characterized in tabular format to understand total
volumetric flow versus fan speed. The BMC calculates an average exit air temperature based
on the total system power, front panel temperature, the volumetric system air flow (cubic feet
per meter or CFM), and altitude range.
The Exit Air temp sensor is only available when PMBus* power supplies are installed.
9.3.10.10 Ethernet Controller Thermal Monitoring
The Intel ® Ethernet Controller I350 supports an on-die thermal sensor. For baseboard
Ethernet controllers that use these devices, the BMC will monitor the sensors and use this
data as an input to the fan speed control. The BMC will instantiate an IPMI temperature sensor
for each device on the baseboard.
9.3.10.11 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/v4 product family
® ® ®
there are 2 memory VRD_HOT# signals per CPU slot. The BMC instantiates one discrete IPMI
sensor for each memory VRD_HOT# signal.
9.3.10.12 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 will instantiate an IPMI temperature sensor for each slot. The
