29. Sensors
Specific server boards may only implement a sub-set of sensors and / or may include additional sensors. The system-
specific details of supported sensors and events are described in the EPS for the specific server board or system. The
actual sensor name associated with a sensor number may vary between server boards or systems.
29.1 Sensor Type Codes
The following tables list the sensor identification numbers and information regarding the sensor type, name, what
thresholds are supported, assertion and de-assertion information, and a brief description of what the sensor is used for.
Refer to the Intelligent Platform Management Interface Specification, Version 2.0, for sensor and event / reading-type
table information.
Sensor Type
x The sensor type references the values in the sensor type codes table in the Intelligent Platform Management
Interface Specification Second Generation v2.0. It provides the context to interpret the sensor.
Event / Reading Type
x The event / reading type references values from the event / reading type code ranges and the generic event /
reading type code tables in the Intelligent Platform Management Interface Specification Second Generation v2.0.
Digital sensors are a specific type of discrete sensors that only have two states.
Event Thresholds / Triggers
x The following event thresholds are supported for threshold type sensors.
[u,l][nr,c,nc] upper non-recoverable, upper critical, upper non-critical, lower non-recoverable, lower critical, lower
non-critical uc, lc upper critical, lower critical
x Event triggers are supported event generating offsets for discrete type sensors. The offsets can be found in the
generic event / reading type code or sensor type code tables in the Intelligent Platform Management Interface
Specification Second Generation v2.0, depending on whether the sensor event / reading type is generic or a
sensor specific response.
Assertion / Deassertion
x Assertion and deassertion indicators reveal the type of events this sensor generates:
As: Assertion
De: Deassertion
Readable Value / Offsets
x Readable value indicates the type of value returned for threshold and other non-discrete type sensors.
x Readable offsets indicate the offsets for discrete sensors that are readable via the Get Sensor Reading command.
Unless otherwise indicated, event triggers are readable. Readable offsets consist of the reading type offsets that
do not generate events.
Event Data
x This is the data that is included in an event message generated by the associated sensor.
x For threshold-based sensors, these abbreviations are used:
R: Reading value
T: Threshold value
Rearm Sensors
x The rearm is a request for the event status for a sensor to be rechecked and updated upon a transition between
good and bad states. Rearming the sensors can be done manually or automatically. This column indicates the type
supported by the sensor. These abbreviations are used in the comment column to describe a sensor:
A: Auto-rearm
M: Manual rearm
I: Rearm by init agent
