Safety Instructions
Before You Begin
Before handling the board, read the instructions and safety guidelines on the following pages to prevent
damage to the product and to ensure your own personal safety. Refer to the "Advisories" section in the
Preface for advisory conventions used in this user's guide, including the distinction between Warnings,
Cautions, Important Notes, and Notes.
• Always use caution when handling/operating the computer. Only qualified, experienced,
authorized electronics service personnel should access the interior of the computer. The power
supplies produce high voltages and energy hazards, which can cause bodily harm.
• Use extreme caution when installing or removing components. Refer to the installation
instructions in this user's guide for precautions and procedures. If you have any questions, please
contact Kontron Technical Support
WARNING
High voltages are present inside the chassis when the unit's power cord is plugged
into an electrical outlet. Turn off system power, turn off the power supply, and then
disconnect the power cord from its source before removing the chassis cover. Turning
off the system power switch does not remove power to components.

Safety Instructions
v AM4301 User's Guide
Preventing Electrostatic Discharge
Static electricity can harm system boards. Perform service at an ESD workstation and follow proper ESD
procedure to reduce the risk of damage to components. Kontron strongly encourages you to follow proper
ESD procedure, which can include wrist straps and smocks, when servicing equipment.
Take the following steps to prevent damage from electrostatic discharge (ESD):
• When unpacking a static-sensitive component from its shipping carton, do not remove the
component's antistatic packing material until you are ready to install the component in a
computer. Just before unwrapping the antistatic packaging, be sure you are at an ESD workstation
or grounded. This will discharge any static electricity that may have built up in your body.
• When transporting a sensitive component, first place it in an antistatic container or packaging.
• Handle all sensitive components at an ESD workstation. If possible, use antistatic floor pads and
workbench pads.
• Handle components and boards with care. Don't touch the components or contacts on a board.
Hold a board by its edges or by its metal mounting bracket.
• Do not handle or store system boards near strong electrostatic, electromagnetic, magnetic, or
radioactive fields.

2.2 Ethernet Interfaces
2.2.1 Intel 82571EB LAN with copper interface
The ATCA AMC interface is implemented with two Intel dual-port Gigabit Ethernet controllers. Each
controller supports two 10/100/1000 Base-T.
The LAN features high performance with TCP/IP and UDP/IP checksum offloading for IPv4 and IPv6,
packet filtering, and jumbo frame up to 16K. See www.intel.com for additional details on this
controller.
2.3 Redundant MMC Flash & FWUM
The MMC microcontroller runs a firmware from its internal 256KB flash. It is programmed by another
microcontroller named FWUM (FirmWare Update Manager). The FWUM keeps the last two copies of
the MMC firmware in dedicated flash memories. It act as a watchdog to the MMC and can rollback a
firmware update in the MMC in case of problems.
The FWUM itself is a microcontroller with internal flash to store MMC firmware image. Functions of
this microntroller are kept to a minimum. The FWUM firmware is field updatable.

2.4 Hardware Management Overview
The AMC Carrier communicates with the Module Management Controller (MMC) using the IPMB_L
channel.
The memory subsystem of the MMC consists of an integrated flash memory to hold the MMC
operation code and integrated RAM for data. The field replacement unit (FRU) inventory
information is stored in the nonvolatile memory on an EEPROM connected via a local I2C interface
to the MMC microcontroller. It is possible to store up to 4 KBytes within the FRU inventory
information. Event generation over IPMB-L bus to reach the AMC Carrier that forward it to the ShMc
ensure that 'post-mortem' logging information is available even if the power of the AMC is
disabled.
The onboard DC voltages and temperature are monitored by the MMC microcontroller device. The
MMC will send an event to the Carrier AMC if any of the thresholds are exceeded.
To increase the reliability of the AM4301 SBC management subsystem, an external watchdog
supervisor only for the MMC is implemented. The MMC must strobe the external watchdog at two-
second intervals to ensure continuity of operation of the board's management subsystem. If the
MMC ceases to strobe the watchdog supervisor, the watchdog isolates the MMC from the IPMBs and
resets the MMC. The watchdog supervisor does not reset the payload power and the restart of the
MMC will not affect the payload and will restore the previous Module Hot Swap state. The watchdog
timeout expires after six seconds if strobes are not generated. The external watchdog supervisor is
not configurable and must not be confused with the IPMI v1.5 watchdog timer commands.
This external watchdog of the MMC is implemented in a second microcontroller. This microcontroller
is responsible to monitor the MMC and to manage MMC fail safe firmware upgrade process. The name
of this second microcontroller is the Firmware Upgrade Manager (FWUM). The FWUM can handle two
Firmware code that are stored in two external SEPROM memories. If a failure occurs during firmware
upgrade, the FWUM will automatically rollback to the redundant MMC firmware image.
2.4.1 Sensor Data Record (SDR)
Every sensor on the baseboard is associated with a Sensor Data Record (SDR). Sensor Data Records
contain information about the sensors identification such as sensor type, sensor name, sensor unit.
SDR also contain the configuration of a specific sensor such as threshold/hystheresis, event
generation capabilities that specifies sensor behaviour. Some fields of the sensor SDR are
configurable through IPMI v1.5 command and are set to built-in initial value. Finally one field wich
is the sensor owner must reflect the module addresses that allow the AMC Carrier to identify the
owner of the SDR when it is scanned from the module management controller and merged within
the AMC Carrier Device SDR repository.

From IPMI prespective, the AM4301 management controller is set up as a satellite management
controller (SMC). It does support sensor devices, and use the IPMI static sensor population feature
of IPMI v1.5 to merge the hot swaped AMC sensor with the carrier board sensors population. The
usual way the AMC Carrier is informed about an AMC insertion is through the AMC Module Hot Swap
sensor and a radial presence line on the AMC connector. All SDRs can be queried using Device SDR
commands to the firmware. Module sensors that have been implemented are listed below.

2.4.2.2 Module Hot Swap
The hot-swap event message conveys the current state of the module, the previous state, and a
cause of the state change as can be determined by the MMC. Refer to AMC.0 R1.0 Specifications for
further details on the module hot-swap state.
2.4.3 Field Replaceable Unit (FRU) Information
The FRU Information provides inventory data about the boards where the FRU Information Device is
located. The part number or version number can be read through software.
FRU information in the AM4301 includes data describing the AM4301 board as per AMC.0 R1.0
specification requirements. This information is retrieved by the Carrier AMC, enabling reporting of
board-specific information through an standardized mechanism.
Following are the definitions for the multirecord implemented by the firmware as part of Module
data.
2.4.4 E-Keying
E-Keying has been defined in the AMC.0 R1.0 Specification to prevent module damage, prevent
misoperation, and verify bay connection compatibility. The FRU data contains the AMC point-to-
point connectivity record as described in Section 3.9.2 of the AMC.0 R1.0 specification.
The Set/Get AMC Port State IPMI commands defined by the AMC.0 specification are used for either
granting or rejecting the E-keys.
2.4.5 MMC Firmware Code
MMC firmware code is organized into boot code and operational code, both of which are stored in a
flash module. Upon an MMC reset, the MMC executes the boot code and performs the following:
1 Self test to verify the status of its hardware and memory.
2 Performs a checksum of the operational code.
3 Communicates with the Firmware Upgrade Manager (FWUM) in order to inform the MMC watchdog that the
actual MMC firmware is suitable for execution.
Upon successful verification of the operational code checksum, the firmware will jump to the
operational code.
