The shelf management system consists of several major components:
 Distributed intelligent management controllers which manage and monitor the operation
and environment conditions of each field replaceable unit (FRU) in the shelf
 Shelf manager which implements a system management interface and contains shelf
management controller (ShMC) through which it communicates with other Intelligent
Platform Management Controllers (IPMCs)
 Intelligent platform management interface (IPMI) infrastructure that provides
communication, management, and control paths among the distributed controllers and
to the shelf manager. The IPMI infrastructure is fully compliant to the IPMI V.1.5 and
AdvancedTCA Specification.
The shelf manager consists of hardware (payload and shelf management controller) and
software.
For a detailed description refer to the ATCA-M100 Reference Guide. For a description of the HPI-
B software refer to the System Management Interface Based on HPI-B (Centellis 31kX /4100) User’s
Guide.
Due to high-availability software which utilizes redundant hardware components, a five-nines
(99.999%) system uptime is ensured. Shelf management software runs on two redundant shelf
manager boards. Software upgrade can be performed via a remote interface.
The shelf manager performs the following main tasks:
 Retrieving FRU inventory information
 Receiving events from sensors of the shelf
 Monitoring and controlling environmental conditions of the shelf
 Reporting of errors
 Executing corrective actions
 Managing interconnect resources in order to prevent damage of the blades due to hot
swap
