Intel® Server Board X38ML

Revision 1.3

Intel order number E15331-006

Sensor Type

The Sensor Type references the values enumerated in the

Sensor Type Codes

table

in the IPMI specification. It provides the context in which to interpret the sensor (for

example, the physical entity or characteristic that is represented by this sensor).

Event/Reading Type

The Event/Reading Type references values from the

Event/Reading Type Code

Ranges

and

Generic Event/Reading Type Codes

tables in the

IPMI specification

Digital sensors are a type of discrete sensors, which have only two states.

Event Thresholds/Triggers

Event Thresholds are supported, event-generating thresholds for Threshold type

sensors.

[u,l][c,nc]

upper critical, upper non-critical, lower critical, lower non-critical

uc, lc

upper critical, lower critical

Event

Triggers are supported, event-generating offsets for Discrete type sensors.

You can find the offsets in the

Generic Event/Reading Type Codes

Sensor Type

Codes

tables in the IPMI specification, depending on whether the sensor

event/reading type is generic or a sensor specific response.

Assertion/Deassertion

Assertion and Deassertion

indicators reveal what type of events this sensor generates:

As: Assertions

De: Deassertion

Readable Value/Offsets

Readable Value indicates the type of value returned for threshold and other non-

discrete type sensors.

Readable Offsets indicates the offsets for discrete sensors that are readable via the

Get Sensor Reading

command. Unless otherwise indicated, all Event Triggers are

readable (for example,

Readable Offsets

consists of the reading type offsets that do

not generate events).

Event Data

This is the data included in an event message generated by the associated sensor.

For threshold-based sensors, the following abbreviations are used:

R: Reading value

T: Threshold value

Re-arm Sensors

The re-arm is a request from the event status for a sensor to be rechecked and updated

upon a transition between good and bad states. The sensors can be re-armed manually

or automatically. This column indicates the type supported by the sensor. The following

abbreviations are used in the comment column to describe a sensor:

A: Auto-re-arm

M: Manual re-arm
