Sensor Name Per-Processor
Socket
Description
Digital Thermal Sensor Yes Relative temperature reading by means of PECI
Processor VRD Over-Temperature
Indication
Yes Discrete sensor that indicates a processor VRD has
crossed an upper operating temperature threshold
Processor Voltage Yes Threshold sensor that indicates a processor
power-good state
Processor Thermal Control (Prochot) Yes Percentage of time a processor is throttling due to
thermal conditions
5.3.11.1 Processor Status Sensors
The BMC provides an IPMI sensor of type processor for monitoring status information for each
processor slot. If an event state (sensor offset) has been asserted, it remains asserted until one
of the following happens:
1. A Rearm Sensor Events command is executed for the processor status sensor.
2. An AC or DC power cycle, system reset, or system boot occurs.
The BMC provides system status indication to the front panel LEDs for processor fault
conditions shown in Table 11.
CPU Presence status is not saved across AC power cycles and therefore will not generate a
de-assertion after cycling AC power.
Table 11. Processor Status Sensor Implementation
Offset Processor Status Detected By
0 Internal error (IERR) Not Supported
1 Thermal trip BMC
2 FRB1/BIST failure Not Supported
3 FRB2/Hang in POST failure BIOS
1
4 FRB3/Processor startup/initialization failure (CPU fails to start) Not Supported
5 Configuration error (for DMI) BIOS
1
6 SM BIOS uncorrectable CPU-complex error Not Supported
7 Processor presence detected BMC
8 Processor disabled Not Supported
9 Terminator presence detected Not Supported
Note:
1. Fault is not reflected in the processor status sensor.
5.3.11.2 Processor Population Fault (CPU Missing) Sensor
The BMC supports a Processor Population Fault sensor. This is used to monitor for the
condition in which processor slots are not populated as required by the platform HW to allow
power-on of the system.
