9.2 Introduction
The Schroff Shelf Manager ACB-V is a 78 mm x 280 mm board that fits into a dedicated Shelf
Manager slot in a Schroff 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 Sys-
tem 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

500
(
ShMM-500
), a compact SO-DIMM form-factor module, installed on the ACB-V carrier
board.
The ACB-V carrier board includes several on-board devices that enable different aspects of
Shelf management based on the ShMM-500. These facilities include I²C-based hardware
monitoring/control and GPIO expander devices.
The ACB-V provides the Fan Controller for up to 9 Fans and individual Ethernet connections
to both Base Hubs (ShMC cross connect).
The Shelf Manager also provides an IPMB interface for the non-intelligent FRUs in a Schroff
Shelf. The Shelf Manager communicate with the non-intelligent FRUs over I²C busses and
expose the sensors for these FRUs at IPMB address 0x20.
To maximize availability, the Schroff ATCA Shelves are designed to work with two redundant
Schroff ShMM-ACB-V Shelf Managers.
