9.2 Introduction
The Shelf Manager is a 78mmX280mm board that fits into a dedicated Shelf Manager slot in
an ATCA Shelf.
The Shelf Manager has two main responsibilities:
1. Manage/track the FRU population and common infrastructure of a Shelf,
especially the power, cooling and interconnect resources and their usage.
2. Enable the overall system manager to join in that management/tracking
through the System Manager Interface, which is typically implemented over
Ethernet.
The Shelf management based on the Pigeon Point Shelf management solution for
AdvancedTCA products.
The Shelf management software executes on the pigeon point Shelf Management
Mezzanine 700 (ShMM-700), a compact SO-DIMM form-factor module, installed on
the carrier board.
The carrier board includes several onboard devices that enable different aspects of Shelf
management based on the ShMM-700. These facilities include I2C-based hardware
monitoring/control and GPIO expander devices.
To maximize availability, the ATCA Shelves are designed to work with two redundant Shelf
Managers.
