ENTITIES AND ENTITY ASSOCIATIONS
The AdvancedTCA specification (see PICMG Engineering Change Notice 3.0 listed in Tab le 1 -
3
) 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 KAT4000 (CPU and no PCIe configuration) installed in Logical Slot
1 (IPMB 82) has the description in
Fig.9-4.
