Emerson 4620 Manuel D’Utilisation

The following limitations apply with respect to the compatibility with the HPI-B-AdvancedTCA 
mapping specification SAIM-HPI-B.01.01-ATCA. Note that these limitations apply to the current 
and also to all future Emerson HPI-B releases. There are no plans to implement these features 
in the future. 

z

Only physical slot numbers are supported
Emerson HPI-B only supports physical slot numbers in entity paths

z

Only "shall" and "should" requirements are supported 
Emerson HPI-B only supports the "shall" and "should" requirements of the HPI-to-
AdvancedTCA mapping specification SAIM-HPI-B.01.01-ATCA. 

The multishelf HPI library allows your application to connect to and manage several shelves at 
the same time. For this purpose the multishelf library provides several HPI controls which allow 
the application to manage the connection to shelves and also to dynamically add and remove 
shelves to the HPI environment. This section provides all the information that you need to know 
in order to use these HPI controls and work with the HPI multishelf library. 

HPI uses the concept of domains. Generally, a domain represents one shelf. Furthermore there 
is a default domain. It acts as a container for all other domains and does itself not represent 
actual hardware. 

It is possible for multiple domains to represent the same physical shelf. This is for example the 
case in typical AdvancedTCA systems which often provide two shelf managers with an HPI 
daemon running on each of them.
