2.2 Intelligent Platform Management Bus (IPMB)
The Shelf uses an Intelligent Platform Management Bus (IPMB) for management
communications among all ATCA Boards, the Fan Trays and the Shelf Managers. The reliability
of the IPMB is improved by the addition of a second IPMB, with the two IPMBs referenced as
IPMB-A and IPMB-B.
IPMB-A and IPMB-B are routed to the ATCA slots in a bussed configuration. 
Figure 4: IPMB

2.3 Shelf SEEPROM
The Shelf SEEPROM is a repository of the shelf specific information, capabilities of the system
and other user configurable options.
The SEEPROM contains as example:
-
a list of which slots are connected together
how the update channels are routed
how many slots are in the system
what the maximum power is to each slot
the serial number of the Shelf
the backplane topology etc.
The Shelf Managers use this information to provide functions such as electronic keying,
controlling the power state of the system, etc.
The Shelf Managers cache the information that is stored in the SEEPROMs so that the
SEEPROM is only needed when the Shelf Managers are first inserted or when the Shelf is first
turned on.
The redundant SEEPROMs ensure that if one is corrupt or non-functional, the second can
provide the necessary information. The Shelf Manager selects what set of information is
correct and then synchronizes the two SEEPROMs from the internally cached copy of the
SEEPROM information.

5 Fan Tray
5.1 Introduction
The Fan Tray is an intelligent FRU controlled by the ShMCs via IPMB.
The interchangeable Fan Tray is equipped with 8 high speed / high air flow fans controlled as
a group by the IPM Controller in the Fan Tray.
The Fan Tray is locked into the Shelf with captive screws. A hot-swap push button is used to
provide hot-swap functionality.
The Fan Tray provides:
• A blue Hot Swap LED
• A red Fan Tray Alarm LED
• A green Fan Tray OK LED
• A Hot Swap push button
The Fan Tray is controlled via an on-board IPM controller. The Shelf Manager performs
management of the Fan Tray through the two independent bussed IPMB connections.
With optional on-blade shelf management, the circuit breaker status signals of the PEM and
the SEEPROM on the backplane are connected to the internal I²C bus on the Fan Trays. The
on-blade Shelf Manager has access to these components via the IPM controller of the Fan
Trays.
The speed of each individual fan is monitored. If any of the fan speeds drops below the
desired fan speed, a System Event Log (SEL) entry is logged by the Shelf Manager. The Shelf
Manager then generates alerts and sets alarm conditions as necessary.
The system is designed to run indefinitely with any single fan failure. When one fan fails, all
other fans are set to full speed.
Caution!
The fan tray is not redundant. Depending on the operation temperature and the load state
a fan tray swap must be carried out within a maximum of 30 seconds.

5.3 Fan Tray Connectors and Indicators
The front panel includes a green and red status LED and a blue hot-swap LED.
The Hot-Swap push button indicates to the Shelf Managers that the Fan Tray is about to be
removed. Its use is optional, but it is provided so that service personnel can be trained to look
for a blue LED to be illuminated on any active component before removing it from the system.
Once the operator pushes the Hot-Swap button, the Shelf Manager is informed of the
pending extraction. When the Shelf Manager feels it is “safe“ to remove the Fan Tray, the
blue Hot-Swap LED illuminates solid.

5.4 Fan Control
The Fan Tray‘s on-board IPM controller has 2 operation modes:
Shelf Manager Mode:
The Shelf Manager performs management of the Fan Tray through the two independent
bussed IPMB connections.
Autonomous Mode:
When the connection to the Shelf Manager is lost, or the Shelf Manger is absent, the fan
controller takes over the fan control after 65 seconds.
4 different control behaviours are user-selectable by a DIP-switch located at the fan tray‘s
rear side.
(1) Full speed
Fan level is set to maximum (15)
(2) Outlet temperature based control
The fan level depends on the reading of the NTC sensor above the card cage and the
selected curve
(3) Intake temperature based control
The fan level depends on the reading of the LM75 temperature on the fan tray PCB
and the selected curve
(4) Differential temperature based control
The fan controller adjusts the fan speed according to the difference between the
intake temperature and the outlet temperature. The intake temperature is determined by an LM75 temperature sensor on the an tray PCB, the outlet temperature by
an NTC sensors located above the card cage

6 Power
Hazardous voltage!
Before working ensure that the power is removed from the power connection 
cables.
The shelf supports low power and high power DC-Power Entry Modules (PEMs) with or
without redundant inputs.
The pluggable DC Power Entry Module (PEM) is located at the rear bottom side of the Shelf.
The PEM provides power terminals for 100 A power feeds. Each power feed consists of a 
–48 VDC cable and its corresponding RTN cable.
The power filtering consists of filtered power terminals and a discrete line-filter for each
power branch.The input voltage range for the Shelf is from -40 VDC to -75 VDC.
Overcurrent protection is provided by 100 A circuit breakers in the -48 VDC input lines.
Power distribution within the PEM is divided into 4 power branches.
The System can be powered using a regular telecommunication power supply of -48/-60 VDC
with a VDC return. The specified voltage range is from -40 VDC to-75 VDC. The Shelf supports
redundant power inputs but the two inputs should be independently powered.

The documentation is available for registered users at www.schroff.biz
Shelf Manager with bused IPMB: 21990-401 (Product Number)
21990-404 (Catalog Number with packaging)
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:
• Manage/track the FRU population and common infrastructure of a Shelf, especially the
power, cooling and interconnect resources and their usage.
• 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 Shelf Management Mezzanine 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 nonintelligent FRUs over I²C busses and expose the sensors for these FRUs at IPMB address 0x20.

8.2 Bused IPMB Interface
The ShMM-700R provides two IPMBs. The IPMB-A and IPMB-B from the ShMM-700R are
routed to the Backplane connector through I2c buffers. The ATCA Backplane buses the two
IPMBs to the ATCA boards.
The Active# signal of the ShMM-700R is used to switch on/off the pull-up resistors of the
IPMBs.

8.3 Ethernet Interfaces
The front panel ETH0 Ethernet connector is intended for service use only or for debugging
purposes in laboratory environment. The computer which is connected to this interface must
be located nearby the shelf manager with an Ethernet cable that is not longer than 10 m.
The front panel Ethernet connector MUST NOT be connected to a Telecommunication
Network Circuit that leaves the building.
The ETH0 interface of the shelf manager can manually be switched between the front panel
RJ45 connector (“Front”-position of the rocker-switches) and the backplane connector going
to the hub board base interface (“Back”-position of the rocker-switches).
The ATCA specification requires a base channel interface between the shelf manager and the
Hub board. The ETH0 rocker-switches MUST be in “Back”-position in normal operation of the
shelf manager in an ATCA-shelf.

8.8 Redundancy Control
The Shelf Manager supports redundant operation with automatic switchover using
redundant Shelf Managers. In a configuration where two Shelf Manager are present, one acts
as the active Shelf Manager and the other as a standby. The Shelf Managers monitor each
other and either can trigger a switchover if necessary.
8.8.1 Hardware Redundancy Interface
The two Shelf Manager communicate over the TCP/IP based Software Redundancy Interface
(SRI) which is implemented via a pair of USB links between the ShMM-700Rs. The active
instance posts incremental state updates to the backup via this interface. As a result, the
backup can quickly step into the active role if necessary.
The Hardware Redundancy Interface (HRI) between the two Shelf Manager instances enables
the exchange of hardware level ShMM-700R state information, including the following:
• Presence: each Shelf Manager instance knows whether the other instance is present in
the shelf.
• Health: each instance knows whether the other instance considers itself „healthy“.
• Switchover: the backup instance can force a switchover if necessary.
The ACB-VI Hardware Redundancy Interface supports the upgrade from ACB-V to ACB-VI in
an ATCA System without interruption. For details see the firmware release note.

8.9 Command Line Interface (CLI)
The Command Line Interface (CLI) connects to and communicates with the IPM-devices of the
Shelf, the boards, and the Shelf Manager.
The CLI is an IPMI-based library of commands, service personnel or system administrators can
access the CLI through Telnet, SSH, or the Shelf Managers serial port on the SAP.
With the CLI, users can access information about the current system status including sensor
values, threshold settings etc.
Users can also access and modify Shelf- and Shelf Manager configurations, perform actions
on a FRU a.e. set fan speeds etc.
The default user account is “root“ and there is no password.
The default IP address of the primary Shelf Manager is 192.168.0.2
To access all sensor data you have to connect to the active Shelf Manager!
