3.1.5 Recommended PET Frame Values
This section describes the format for various PET frames. A given managed client is not required
to support all the listed PET frames, but if a client supports the event described by one of the
listed PET frames, the client should format the PET frame as described in this section.
3.1.5.1 Environmental Events
This table describes the Specific Trap Field values for common environmental events. An
implementation has options as to whether it returns generic information that just indicates the
criticality of the event, or whether it returns information also indicating that the event was
triggered by a rising or falling condition on the monitored parameter, e.g. whether an over-
temperature or under-temperature condition caused the event.
The list is presented as a guide only. It is not intended to represent a complete list of the possible
environmental events from a system. Management consoles that interpret events should be
prepared to accept any of the possible specified Event Sensor Type, Event Type and Event
Offset values documented by [PET].
The Entity for a given event varies according to what system device the environmental sensor is
monitoring. For example, a typical managed client can have temperature monitoring associated
with its system board and with the main processor. A thermal event associated with the system
board will have Entity set to 7 (System Board) and Entity Instance set to 1 (Primary), while a
thermal event associated with the processor will have Entity set to 3 (Processor) and Entity
Instance set to 1 (Primary).
