System Management: Entities and Entity Associations
ATCA-9305 User’s Manual 10009109-01
7-46
The command returns 0xC0 when the IPMC is busy and will retry until the command is suc-
cessful. If this command returns 0xCC, the sensor ID is invalid. There is only one sensor on
the board, so the sensor ID should always be “0”. When updated, the shelf manager is noti-
fied.

ENTITIES AND ENTITY ASSOCIATIONS
The AdvancedTCA specification (see PICMG Engineering Change Notice 3.0 listed in Ta bl e 1 -2 )
uses Entity IDs and Instances to describe physical components associated with FRUs.
Device-relative Entities are unique to a specific IPMC and are referenced as follows in the
specification:
r(<ipmb>,<lun>,<Entity ID>,<Entity Instance - 60>)
Using this terminology, a ATCA-9305 installed in Logical Slot 1 has the following description
in
Fig. 7-6.
