Emerson 4620 manual Working with the Multishelf Library, Overview

Using HPI-B Limitations with Respect to HPI-B AdvancedTCA Mapping Specification

4.2.2Limitations with Respect to HPI-B AdvancedTCA Mapping Specification

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.

zOnly physical slot numbers are supported

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

zOnly "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.

4.3Working with the Multishelf Library

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.

4.3.1Overview

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.
