1.5 Product Definition
The Schroff Shelf Manager ACB-VI 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 an external System Manager to join in management/tracking through the System
Manager Interface, which is typically implemented over Ethernet.
The Shelf management is based on the Pigeon Point Shelf management solution for
AdvancedTCA products.
The Shelf management software runs on the Pigeon Point

700
(
ShMM-700R
), a compact 204-pin SO-DIMM form-factor module, installed on the
ACB-VI carrier board.
The ACB-VI carrier board includes several on-board devices that enable different aspects of
Shelf management based on the ShMM-700R. These facilities include I²C-based hardware
monitoring/control and GPIO expander devices.
The ACB-VI also provides the Fan Controller for up to 9 Fans and individual Ethernet
connections to both Base Hubs (ShMC cross connect).
The Shelf Manager communicates inside the Shelf with IPM controllers over the Intelligent
Platform Management Bus (IPMB). The Shelf Manager also provides an IPMB interface for the
non-intelligent FRUs in a Schroff Shelf. The Shelf Manager communicates with the non-
intelligent FRUs over I²C busses and expose the sensors for these FRUs at IPMB address 0x20.
Shelf Manager with bused IPMB: 21990-401 (Product Number)
21990-404 (Catalog Number with packaging)
Shelf Manager with radial IPMB: 21990-402 (Product Number)
21990-405 (Catalog Number with packaging)
The new ACB-VI is plug-compatible with the ACB-V but the Shelf‘s FRU-data file
must be updated.
The ACB-V and ACB-VI shelf manager support converting a live shelf from
ACB-V to ACB-VI without losing manageabilty of the shelf. Please see
Schroff‘s firmware release notes for details.
