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 Sh elf M anagement M ezzanine
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.
