Shelf Manager ACB-VI
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 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.
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.

4 RS-232 Interfaces
The ACB-VI provides two RS-232 interfaces. The first serial port is implemented using the UART0, the second serial port is implemented using the UART1 on the ShMM-700R. The first serial interface provides a full set of RS-232 signals, including modem control. In a Schroff Shelf these signals are routed through the backplane connector to the SAP. The SAP provides two 8-pin RJ45 modular receptacles for the serial interfaces of both Shelf Managers. The second serial interface does not provide modem control signals. These signals are also routed to the backplane connector but not used in the Schroff ATCA Shelves.

Depending on the model of the Shelf, the RJ45 connector may have a different pinout of the serial console signals. Refer to the Shelf manual for detailed information.
5 Ethernet Interface
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.

6 Shelf Manager and Shelf Alarm Panel
Some Shelf Manager I/O function have been moved to a separate Board called a Shelf Alarm Panel (SAP). The SAP provides the RJ45 Serial Console connectors, Telco Alarm Interface, user definable LEDs and custom specific I/Os for the Shelf Manager. Only the active Shelf Manager has access to the SAP and can control the Alarms. The advantage of this approach is that the SAP is separated from the Shelf Manager and can be located at a position at the Chassis that is easy to reach and operate by service personnel.
The figure below shows the interconnection between the Shelf Managers and the SAP. Please note that the design of the SAP is Shelf dependent. Please see your Shelf User Manual for the actual SAP-implementation in your Shelf.
Please see chapter ,,Telco Alarms" for detailed information concerning the Telco Alarm interface and the user definable LEDs.

7 Master-Only I²C Bus
The ACB-VI carrier board has a number of onboard I²C devices connected to the local I²C bus. These devices are: · PCA9554: reads the hardware address at the backplane connector · PCA9555: monitors the presence signals from the PEMs, SAP, Air Filter, Fan Trays and the
presence of the input voltages and fuses. · ADT7490: monitor voltages, monitor/controls the Fan Trays · LM75: on-board temperature · SEEPROM: Shelf Manager FRU information · PCA9543: This 2-channel switch divides the I²C-bus 3 into 2 channels to:
- the SAP (Channel 0) - the PEMs (Channel 4)
The 'Active' signal of the ShMM-700R is used to enable the LTC4300, so that only the active Shelf Manager has access to the Shelf I²C-bus devices.

8.0.1 DC-DC Converter
The DC-DC converter on the ACB-VI provides the power for all on-board devices and all offboard I²C devices inside the Shelf. The 3.6 V local power is routed through two current limiting circuits to create two redundant voltages, I2C_PWR_A and I2C_PWR_B. I2C_PWR_A and I2C_PWR_B are routed to the backplane connector and used to power I²Cdevices on FRUs like the Fan Tray, PEM or SAP. If one of these voltages is short circuited in a chassis FRU or on the backplane, the short circuit current is limited to 700 - 900 mA so that the Shelf Manager and the FRUs are still fully operational.

9 Fan Control
The Shelf Manager provides fan control functionality through the ADT7490 fan controllers.
The fan speed is controlled by a PWM signal generated on the ADT7490 0x2E. The PWM output from the ADT7490 is buffered and enabled by the Carrier_Active signal so that only the active Shelf Manager controls the fan speed. The PWM signal is opto-isolated and routed to the backplane connector. For voltage-regulated Fans the Shelf Manager provides an integrator that converts the PWM signal into a DC-voltage of 0 V to 10 V, referenced to the ground level of the Fan Tray electronics (FAN_24V_RTN), which is also available on the backplane connector.
The tachometer signals from the Fans are routed through the backplane connector to the opto-isolated tachometer inputs of the 3 ADT7490.
Three digital inputs to the PCA9555 (I/O 1.0....I/O 1.2) are used to detect presence of the Fan Trays. The Fan Tray grounds the signal to indicate that it is installed.
The Shelf Manager's fan tachometer inputs and fan control outputs (DC, PWM) are optically isolated from primary voltages of the fans. The primary side of the opto couplers is powered by a 24 V voltage (FAN_24V) which is generated on the Fan Trays and routed together with the Fan Tray ground reference (FAN _24V_RTN) to the Shelf Manager.

10 Hardware Address
The PCA9554 on the ACB-VI reads the hardware address and parity bit from the backplane connector of the dedicated Shelf Manager slot. Geographic address pins (HA[0], HA7) at the Backplane connector determine bit 0 and bit 7, bit 1 to bit 6 are hardware-coded on the Shelf Manager PCB. The ShMM-700R software determines the hardware address by reading the input port register of the PCA9554 at address 0x23.

12 Redundancy Control
The Shelf Manager supports redundant operation with automatic switch-over 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.
12.0.1 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 notes.
13 Hot Swap Interface
The ACB-VI provides a Hot Swap interface allowing the ACB-VI to be replaced without powering down the Shelf. The interface is composed of three components:
· Hot Swap switch at injector/ejector handle
· Presence signal indicating that the ACB-VI is fully seated in its backplane connector
· Hot Swap LED
13.1 Hot Swap LED
The Shelf Manager provides a a blue Hot Swap LED. The LED indicates when it is safe to "remove" the Shelf Manager from a powered Shelf.

Shelf Manager ACB-VI
14 Telco Alarms
The Shelf Manager ACB-VI can manage a Telco Alarm Interface with the following components: · Telco Alarm connector · Telco Alarm LEDs · Telco Alarm Cutoff push button
In Schroff Shelves these components are located on a separate board called Shelf Alarm Panel (SAP). All three aspects of Telco interface are controlled by a PCA9555 located on the SAP. The PCA 9555 is connected to the Shelf Manager via an I²C connection. The Shelf management software running on the ShMM-700R is responsible for: · configuring the PCA9555 as inputs or outputs, as appropriate for the Telco interface
signals. · reading and writing GPIO port registers at appropriate times.
The PCA9555 generates an active low interrupt output when one of the inputs changes its value. That interrupt output is routed on the ACB-VI onto the shared interrupt line going to the INT# input of the ShMM-700R. Software running on the ShMM-700R is responsible for reacting to an input change when an interrupt is triggered by the PCA9555.
For more information see the Chapter ,,SAP" in the Shelf's User Manual.
