2. Installation

The AT8901 has been designed for easy installation. However, the following standard precau­tions, installation procedures, and general information must be observed to ensure proper in­stallation and to preclude damage to the board, other system components, or injury to
personnel.

2.1 Safety Requirements

The following safety precautions must be observed when installing or operating the AT8901.
Kontron assumes no responsibility for any damage resulting from failure to comply with these
requirements.

Warning!

Due care should be exercised when handling the board due to the fact that the
heat sink can get very hot. Do not touch the heat sink when installing or
removing the board.

In addition, the board should not be placed on any surface or in any form of stor­age container until such time as the board and heat sink have cooled down to
room temperature.

Note ...

Certain ATCA boards require bus master and/or rear I/O capability. If you are
in doubt whether such features are required for the board you intend to install,
please check your specific board and/or system documentation to make sure
that your system is provided with an appropriate free slot in which to insert the
board.

ESD Equipment!

This ATCA board contains electrostatically sensitive devices. Please observe
the necessary precautions to avoid damage to your board:

• Discharge your clothing before touching the assembly. Tools must be dis­charged before use.

• 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, electro-

magnetic, magnetic, or radioactive fields.

2.2 AT8901 Initial Installation Procedures

The following procedures are applicable only for the initial installation of the AT8901 in a sys­tem. Procedures for standard removal and hot swap operations are found in their respective
chapters.

To perform an initial installation of the AT8901 in a system proceed as follows:

1. Ensure that the safety requirements indicated in section 2.1. are observed.

Warning!

Failure to comply with the instruction below may cause damage to the
board or result in improper system operation.

2. Ensure that the board is properly configured for operation in accordance with application
requirements before installing. For information regarding the configuration of the AT8901
refer to Chapter 4. For the installation of AT8901 specific peripheral devices and rear I/O
devices refer to the appropriate chapters.

Warning!

Care must be taken when applying the procedures below to ensure that
neither the AT8901 nor other system boards are physically damaged by
the application of these procedures.

3. To install the AT8901 perform the following:

1. Carefully insert the board into the slot designated by the application requirements for
the board until it makes contact with the backplane connectors.

Warning!

DO NOT push the board into the backplane connectors. Use the ejector
handles to seat the board into the backplane connectors.

2. Using the ejector handle, engage the board with the backplane. When the ejector han­dle is locked, the board is engaged.

3. Fasten the front panel retaining screws.

4. Connect all external interfacing cables to the board as required.

5. Ensure that the board and all required interfacing cables are properly secured.

AT8901 Installation

2.3 Standard Removal Procedures

To remove the board proceed as follows:

1. Ensure that the safety requirements indicated in section 2.1. are observed.

Warning!

Care must be taken when applying the procedures below to ensure that
neither the AT8901 nor system boards are physically damaged by the
application of these procedures.

2. Disconnect any interfacing cables that may be connected to the board.

3. Unscrew the front panel retaining screws.

4. Wait until the blue LED is fully ON, this mean that the hot swap sequence is ready for board removal.

5. Disengage the board from the backplane by using both board ejection handles

6. After disengaging the board from the backplane, pull the board out of the slot.

2.4 AMC Installation

To install an AMC proceed as follows:

1. Remove the AMC filler panel.

2. Carefully engage the AMC into the card guide. Push the AMC until it fully mate with its con-

nector. Secure the AMC handle to the locking position.

3. In normal condition, the blue LED shall turn ON as soon as the AMC is fully inserted. It will

turn OFF at the end of the hot swap sequence.

2.5 Software Installation

The AT8901 comes as a pre-installed system with all necessary OS, Filesystem, drivers and
applications factory-installed with default configurations.

Updating the Software with new Operating System or applications or new versions is provided
by a dedicated update mechanism, which is described in Chapter 4.

2.6 CLI Quick Start

This section gives instructions for (initially) accessing the CLI (Command Line Interface) of the
AT8901 Base Fabric using either the Serial Console or the Fast Ethernet management inter­face (serviceport) on the front plate.

Serial Console CLI can be accessed directly with the appropriate cabling. A console menu al­lows to enter the Base Fabric console or to perform a system reset. Fast Ethernet access is
done by establishing a telnet connection (see below).

Page 2 - 4 AT8901 User Guide

AT8901 Installation

In order to use the Fast Ethernet management port for CLI telnet access, an IP address must
be assigned. This implies that at least the first CLI access has to be done by Serial Console in
order to configure the serviceport IP settings. The corresponding procedure is described in the
following. User input is printed in bold letters.

1. Connect to serial port on AT8901 front plate using the adapter described in Chapter 3, sec-

tion 3.1.

Port settings are:

• 9600 bps

• 8 bit, no parity, 1 stop bit (8N1)

• no flow control

2. Ensure that the board is powered up.

3. Wait for boot process to complete, i.e. until the console selection menu appears.

ShMC Cross-connection

The Hub Board provides two dedicated 10/100BASE-T connections to the shelf managers ac­cording to PICMG 3.0 rev. 2 (redundancy shelf manager cross-connection). Port 0/20 is con­nected to SMCA, 0/24 to SMCB.

AMC GbE Support Channels

Each AMC bay has one GbE connection to the base interface switch (AMC Channel 0). On
Channel 1, AMC bay B1 has an additional link to the backplane update channel buffered by a
cross-point switch. The update channel connects to the base switch of the redundant Hub
Board.

In applications with a PrAMC used as a system controller in the ATCA Hub Board, the system
controller redundancy ensures that a fault in a base switch of one Hub Board does not cut the
connection to the redundant Hub Board (see block diagram below). The connections between
AMC B1 and the backplane are buffered by a cross-point switch that is controlled by the IPMC.

Interconnects to RTM

AMC Bay B1 has eight generic interconnects to the RTM Zone 3 (channels 13 to 20), B2 has
four interconnects (channels 17 to 20). The second SATA/FC port of each AMC Bay (channel

3) is also connected to the RTM.

For further details, please refer to section 3.6., RTM Interface.

AMC GbE Support Channels

The first GbE port of each AMC Bay (channel 0) is connected to the base switch, the second
one (channel 1) of AMC Bay 1 is also connected to the neighbouring Hub Board via Zone 2
Update Channel.

See also section 3.2.

AMC SATA/FC Channels

The first SATA port (channel 2) connects both AMC Bays together. A possible application is a
PrAMC in one Bay and a storage AMC in the other. The second SATA port (channel 3) of each
AMC Bay is connected to the RTM.

3.4 IPMI

The Hub Board supports an intelligent hardware management system, based on the Intelligent
Platform Management Interface (IPMI) Specification 1.5. The hardware management system
provides the ability to manage the power, cooling and interconnect needs of intelligent devices,
to monitor events and to log events to a central repository.

The main building blocks of the IPMI architecture of the AT8901 are:

• IPMC Intelligent Platform Management Controller

• FUM Firmware Update Manager

• CPLD Complex Programmable Logical Device

For further details please refer PICMG 3.0 standard Rev. 2.0.

IPMC

The IPM controller is a 16-bit microcontroller for IPMI applications and it is compliant to IPMI
version 1.5 specification. The microcontroller has large on chip memory of 512 Kbyte Flash and
40 Kbyte SRAM. The microcontroller provides six I2C interfaces to have access to the dedicat­ed ShMCs, the AMCs, the fabric mezzanine module, the RTM and the on board peripheral de­vices such as SEEPROM and temperature sensor. The microcontroller also provides three
serial interfaces that are connected to the CPLD.

An LPC interface using the KCS protocol for communication between IPMC and PPC is imple­mented. IPMC operation is supervised by the FUM.

Page 3 - 11 AT8901 User Guide

AT8901 Hardware Description

FUM

The Firmware Update Manager (FUM) is a microcontroller with embedded 16 Kbyte data flash
ROM and 1 Kbyte RAM.

The FUM is responsible for field upgrades, rollbacks and watchdog functions of the IPM con­troller. Four SPI compatible memory devices are connected to the FUM which build up two IPMI
firmware banks with 512 Kbyte each. One bank contains a copy of the current IPMC code. The
other bank can be written without affecting IPMC operation. Once the bank is updated, the FUM
writes its content into the IPMC. IPMC control signals are all buffered in the CPLD so that board
operation is not affected during update. In the case of a fault during the update process, the
FUM can configure the IPMC with the old firmware that is kept in the other bank. The FUM is
also the watchdog timer for the IPMC. There are several control signals to supervise the IPM
controller.

CPLD

The CPLD is responsible for connecting the PPC to the IPMC and FUM and for handling the
serial interfaces of PPC, IPMC and FUM to the RS232 connector on the front panel. The host
interface between PowerPC and CPLD, realized by PPC’s External Bus Interface (EBC), is
used as CPLD-Register-Interface and as communication interface to IPM controller. The EBC
is configured as a demultiplexed 8 Bit Address/Data interface. For accesses to the IPMC Con­troller, an EBC to LPC (Low Pin Count)-Bridge is included as protocol interface. The LPC inter­face is for communication between IPMC and PPC over KCS protocol. An additional LPC-IF is
connected to the Fabric mezzanine.

The CPLD controls the LEDs for the whole board via shift registers. It handles the signals to
monitor the AMCs, fabric mezzanine module and the RTM and handles the signals for the line
drivers for the synchronization clocks and the AMC GbE support channels.

An internal multiplexer controls the serial interfaces from the PPC, the FUM and the IPMC. It
is possible to connect each device to the other or to the RS232 connector on the front panel.

3.5 Synchronization Clock

The Synchronization Clock Interface provides three differential pairs per AMC for clock distri­bution from the AMCs to the Hub Board and vice versa to enable applications that require the
exchange of synchronous timing information among modules and consequently multiple
boards in a shelf. This allows modules to source clock(s) to the system in the case where it
provides a network interface function, or conversely to receive timing information from another
carrier board or module within the system. The three synchronization clock signals are CLK1,
CLK2, and CLK3, each supported by a differential pair. CLK1 and CLK2 are driven by the
AMCs to the backplane and CLK3 will be received from the backplane. AMC1 and 2 cannot
transmit or receive simultaneously signals to or from the backplane. Either the CLK signals of
AMC1 are valid or the CLK signals of AMC2. The Hub Board cannot receive any synchroniza­tion clocks from other carrier boards, it is only used for distribution. The three differential clock
signals are buffered by three differential line drivers that are controlled by the IPMC and CPLD
respectively.

For further details please refer AMC specification AMC0.RC1.1.

Page 3 - 12 AT8901 User Guide

AT8901 Hardware Description

3.6 RTM Interface

The use of an RTM is optional. I/O signals from the Base Board are routed to Zone 3 where a
connector mates with the RTM. The RTM connection is compliant to the PICMG 3.0 standard.

For the connection between the Hub Board and the RTM two daughter card connectors with
40 differential pairs are used.

Each AMC Bay has eight (B1) or four (B2) pairs of generic interconnects to the RTM Zone 3
(AMC_B1_P13 to AMC_B1_P20 and AMC_B2_P17 to AMC_B2_P20). One SATA/FC inter­face for mass storage from each AMC Slot is implemented (STOR0 and STOR1). Also an I2C
IPMI connection is implemeted for an intelligent RTM.

The Zone 3 connector has the following pin assignment:

3.7.2 Power Distribution

The 48 Volts are supplied by the backplane via two independent rails, primary (A) and second­ary (B). The rails are mixed using power Schottky rectifiers. A 7A fuse protects each -48V line
and a 10A fuse protects each RTN line. A hot swap controller enables the 48V power to the
board.

A quarter brick DC/DC converter transforms the 48 Volts to secondary 12 Volts, which are dis­tributed on the board. The converter allows a maximum of 14A output current.

Two different management voltages (3.3V and 5V) and five payload voltages (3.3V, 2.5V, 1.8V,

1.25V and 1.2V) are generated by point of load converters. These are either switches or linear
regulators.

Page 3 - 15 AT8901 User Guide

AT8901 Hardware Description

The management (or suspend) power is present once the board is connected to the backplane.
It supplies the IPMI part which in turn controls the payload power. The various payload voltages
are sequenced. The initial power up sequence is as follows (20ms delay between steps):

1. 3.3V, 1.8V and fabric mezzanine

2. 2.5V, 1.25V and 1.2V

The Power Down Sequence is performed in reversed order with a 1ms delay.

3.7.3 Power Supply AMCs

Each AMC has its own power supply. The 12V payload power is generated by a hot swap con­troller and for the 3V3 management power a current limit switch is used. The maximum power
dissipation for an AMC is 60W. Both AMCs together must not consume more than 75W.

For further details please refer the AMC Specification.

3.7.4 Power Supply RTM

The RTM has its own power supply. The 12V payload power is generated by a hot swap con­troller and for the management power a current limit switch is used. The maximum power dis­sipation for an RTM is 10W.

For further details please refer the PICMG 3.0 standard.

3.7.5 Power Transients

The board provides continuous operation in the presence of transients shown in the following
table of the PICMG 3.0 standard:

AT8901 Hardware Description

3.7.6 Optional Chassis to Logic Ground Connection

According to NEBS requirement R9-14 of GR-1089-CORE issue 3, the AT8901 provides a con­nection between chassis and logic ground. It is made up of a screw that connects the PCB to
the bottom sheet.

If chassis and logic ground shall be isolated, the screw with its washer can be removed. It is
located near the jumper header J11 and is labelled "GND TO CHASSIS".

3.8 Reset

The reset chain is based on seven elements. The first element in the chain is the voltage supply
monitor, followed by the CPLD, FUM, IPMC, Payload voltage, PPC and Base Interface.

The reset switch will perform a reset on the CPU when pressed for less than 1 second and a
complete board reset (including IPMI) when pressed for more than 2 seconds.

3.9 Jumpers

Five jumpers in the upper right corner allow debug settings (J11). The IPMI override jumpers
enable bypassing communication with the ShMC for bench operation. The JTAG jumpers con­figure the boundary scan path. JTAG operation requires the use of an RTM.

Warning!

Operation with any of these jumpers set is not supported by the standard appli­cation software.

4.3 Bootloader

On the AT8901 Hub Board, the bootloader ‘u-boot‘ (universal bootloader) is used. The boot­loader initializes the main components of the board like CPU, SDRAM, serial lines etc. for op­eration. After this, kernel and application are started from flash.

Page 4 - 7 AT8901 User Guide

AT8901 Software Description

4.3.1 Power On Self Test

4.3.1.1 Test Routines

Upon power on or system reset, the bootloader performs a set of Power On Self Tests (POST)
to check the integrity of specific components. Components where a POST is available are:

• SDRAM

• PPC405 serial line

• PPC405 I2C

• PPC405 FE

In the case that a POST fails, a POST error code is written into the postcode high byte register
of the onboard CPLD. The boot process is not stopped as there are good chances the board
can boot even in case of POST errors. The postcode high byte register is also accessible by
the IPMC which can report error codes to a separate management instance. Thus more com­prehensive diagnostic tests could be started.

The following table shows a list of available POST routines including POST error codes.

Table 4-1: POST routines and error codes

Device Test POST Error Code

SDRAM Data bus - walking 1 test PCW_DLINE

SDRAM Address bus - walking 1 test PCW_ALINE

PPC405 FE Phy access PCW_ETH1

PPC405 FE Phy loopback test using special Ethernet test frame PCW_ETH2

KCS KCS READY signal test KCSCTL

4.3.1.2 Boot Steps

In addition to the Power On Self Tests described above, the bootloader logs the board startup
sequence in the postcode low byte register. A postcode value is written each time a step in the
start sequence has been completed successfully. The postcode stored is also accessible by
the IPMC. In the case that an error occurs during execution of a step, the boot sequence is
stopped because a fatal error has occurred with great likelihood. In this case, a management
instance can read the last postcode written via the IPMC and thus determine where the fatal
error has occurred.

AT8901 Software Description

4.4 IPMI Firmware

The PPC communicates with the Intelligent Platform Management Controller (IPMC) using the
Keyboard Controller Style (KCS) interface. The bootloader is able to communicate with the IP­MC, e.g. for POST error logging purposes and fault resilient purposes.

The memory subsystem of the IPMC consists of an integrated flash memory to hold the IPMC
operation code and integrated RAM for data. The field replaceable unit (FRU) inventory infor­mation is stored in the nonvolatile memory on an EEPROM connected via a local I2C interface
to the IPMC microcontroller. It is possible to store up to 4 Kbytes within the FRU inventory in­formation. Communication over IPMB bus to the ShMC ensures that ‘post-mortem’ logging in­formation is available even if the main processor becomes disabled.

The IPMC provides six I2C bus connections. Two are used as the redundant IPMB bus con­nections to the backplane, one is used for IPMB-L bus with AMC modules, one for the connec­tion to a managed RTM, one for the Base Board and Mezzanine Sensors and one is for local
EEPROM storage.

If an IPMB bus fault or IPMC failure occurs, IPMB isolators are used to switch and isolate the
backplane/system IPMB bus from the faulted Hub Board. If possible, the IPMC activates the
redundant IPMB bus to re-establish system management communication to report the fault.

The onboard DC voltage, current, and temperature sensors are monitored by the IPMC micro­controller continuously. The IPMC will log an event into the ShMC’s System Event Log (SEL)
if any of the thresholds are exceeded.

To increase the reliability of the Hub board management subsystem, an external watchdog su­pervisor for the IPMC is implemented. The IPMC strobes the external watchdog at two-second
intervals to ensure continuity of operation of the board’s management subsystem. If the IPMC
ceases to strobe the watchdog supervisor for more than six seconds, the watchdog isolates the
IPMC from the IPMBs and resets the IPMC. The watchdog supervisor does not reset the pay­load power and the restart of the IPMC will not affect the payload and will restore the previous
Hot Swap state and power level negociated with the ShMC. 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 IPMC is implemented in a second microcontroller. This Firmware
Upgrade Manager (FUM) is responsible for monitoring the IPMC and for managing the IPMC
fail safe firmware upgrade process. The FUM keeps two IPMC Firmware code images in two
external SEEPROM memories. If a failure occurs during firmware upgrade, the FUM will auto­matically rollback to the last known working IPMC firmware image.

Page 4 - 10 AT8901 User Guide

AT8901 Software Description

4.4.1 Sensor Data Record (SDR)

Every sensor on the Base Board is associated with a Sensor Data Record (SDR). Sensor Data
Records contain information about the sensor’s identification such as sensor type, sensor
name, sensor unit. SDR also contain the configuration of a specific sensor such as thresh­old/hystheresis and event generation capabilities that specifies sensor behaviour. Some field
of the sensor SDR are configurable through IPMI v1.5 commands and are set to built-in initial
value. The AT8902 management controller supports sensor devices and uses the IPMI dynam­ic sensor population feature of IPMI v1.5 to merge the AMC hot swap sensor with the AT8902
sensors population. AMC hot swap events indicated by this sensor are passed to the ShMC.
Additionally, the IPMC updates the sensor population change indicator timestamp accessible
through the Get Device SDR Info command to remain compliant to IPMI v1.5.

All SDRs can be queried using Device SDR commands. Base Board sensors that have been
implemented are listed below.

4.4.1.1 IPMB Link Sensor

The AT8901 provides two IPMB links to increase communication reliability to the shelf manager
and other IPM devices on the IPMB. These IPMB links work together for increased throughput
where both busses are actively used for communication at any time. A request might be re­ceived over IPMB Bus A, and the response is sent over IPMB Bus B. Any requests that time
out are retried on the redundant IPMB bus. In the event of any link state change, the events are
written to the AT8901 SEL. The IPMC monitors the bus for any link failure and isolates itself
from the bus if it detects that it is causing errors on the bus. Events are sent to signal the failure
of a bus or, conversely, the recovery of a bus.

4.4.1.2 FRU Hot Swap

The hot swap event message conveys the current state of the FRU, the previous state, and a
cause of the state change as can be determined by the IPMC. Refer to PICMG 3.0 Specifica­tions for further details on the hot swap state.

4.4.1.3 Fabric Presence Sensor

The FPS indicates if an optional Extension Fabric Mezzanine is present.

4.4.1.4 CPU Status

The CPU Status is set if the PPC experiences a machine check error.

4.4.1.5 POSTCODE

The IPMC has access to the POSTCODE registers in the CPLD. Refer to chapter 4.3.1.2 (Boot
Steps).

4.4.1.6 Health Error

The Health Error is asserted if one of the sensors in Table 4-3: (AT8901 sensors) matches the
Health LED/Sensor condition.

AT8901 Software Description

4.4.2 Field Replaceable Unit (FRU) Information

4.4.2.1 Base Board FRU Information

This FRU information contains the IPMI defined Board and Product Information areas that hold
the part number and serial number of the board and the Multirecord Information Area that con­tains the PICMG defined Point to Point Information records.

The Internal Use Area is preallocated to 384 bytes and is free for customer use.

This FRU information responds to FRU ID #0, which is the ID for the IPMC.

4.4.2.2 Mezzanine FRU Information

The FRU information of any optional Mezzanine Extension responds to FRU ID #3 and is
manged by the IPMC. This FRU information contains the IPMI defined Board and Product In­formation Areas and contains the part number and serial number of the mezzanine.

4.4.3 E-Keying

E-Keying has been defined in the PICMG 3.0 Specification to prevent board damage, prevent
misoperation, and verify fabric compatibility. The FRU data contains the board point-to-point
connectivity record as described in Section 3.7.2.3 of the PICMG 3.0 specification.

When the board enters M3 power state, the shelf manager reads in the board point-to-point
connectivity record from FRU and determines whether the board can enable the Gigabit Eth­ernet ports to the back plane. Set/Get Port State IPMI commands defined by the PICMG 3.0
specification are used for either granting or rejecting the E-keys.

Additional E-Keying is prodived for connectivity between the AMC carrier and the AMC bays
as described the in Section 3.9 and 3.7 of the AMC.0 RC.1.1 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.

4.4.4 IPMC Firmware Code

IPMC firmware code is organized into boot code and operational code, both of which are stored
in a flash module. Upon an IPMC reset, the IPMC executes the boot code and performs the
following:

1. Self test to verify the status of its hardware and memory.

2. Calculates a checksum of the operational code.

3. Communicates with the Firmware Upgrade Manager (FUM) in order to inform the IPMC watchdog that the current IPMC firmware is suitable for execution.

Upon successful verification of the operational code checksum, the firmware will jump to the
operational code.

4.4.5.2 Out-Of-Service (OOS) LED (ATCA LED1)

The AT8901 supports a red Out of Service LED mounted on the front panel. The position of this
LED is near the top handle besides the blue Hot Swap led. The on-board FWUM or the IPMC
can drive this LED to indicate the service state of the IPMC. The OEM application can also drive
this LED using the PICMG LED control APIs. The following states are possible:

Table 4-5: OOS LED state

LED state Description

ON Out of service condition, the IPMC is hold in reset

OFF Normal/Idle board is in service, unless blue led is on

Blink (50/50) The FUM is programming the IPMC due to a firmware update or a rollback

Short blink Power denied condition detected:

Payload has been left in M3 state for more than 30 secs or SetPowerLevel
‘0‘ has been received while in M2 or M3 state

Other application defined LED usage may be implemented.

The AT8901 AMC.0 carrier also implements the OOS LED “Short blink” mode for its Advanced­MC mates on detection of “power denied” conditions.

LED state Description

Short blink Power denied condition detected:

AMC current draw requirements exceed carrier power budget or SetPower­Level ‘0‘ has been received while in M2 or M3 state

As per AMC.0, if the AMC current draw requirements exceed AMC.0 carrier power budget, the
AT8901 will keep the AMC in M1 state with the blue Hot Swap LED in the ON state.

4.4.6 Hot Swap Process

The AT8901 Hub Board has the ability to be hot-swapped in and out of a chassis. The onboard
IPMC manages the power-up and power-down transitions.

In addition to captive retaining screws, the Hub Board has two ejector mechanisms to provide
a positive cam action; this ensures the blade is properly seated. The bottom ejector handle also
has a switch that is connected to the IPMC to determine if the board has been properly inserted.

When the lower ejector handle is disengaged from the faceplate, the hot swap switch will assert
a signal to the IPMC, and the IPMC will move from the M4 state to the M5 state. At the M5 state,
the IPMC will ask the ShMC for permission to move to the M6 state. The Hot Swap LED will
indicate this state with a short blink. Once permission is received from the ShMC or higher-level
software, the board will move to the M6 state.

The ShMC or higher level software can reject the request to move to the M6 state. If this occurs,
the Hot Swap LED returns to a solid off condition, indicating that the Hub Board has returned
to M4 state.

If the Hub Board reaches the M6 state, either through an extraction request through the lower
ejector handle or a direct command from higher-level software. The Hot Swap LED continues
to flash during this preparation time, just like it does in M5 state. When payload power is suc­cessfully turned off, the Hot Swap LED remains lit, indicating it is safe to remove the Hub board
from the chassis.

AT8901 Software Description

4.5 Firmware Administration

A running AT8901 system requires – after the bootloader has passed control to the kernel –
the kernel itself, the root file system (initrd), the FASTPATH switching application and a config­uration file for base and fabric switch. These software components, together with the IPMC im­age, make up the AT8901 firmware.

The flash holding the software is divided into twelve partitions. There are partitions to store two
bootloader, three kernel and three initrd images. Two partitions are reserved for the bootloader
environments, one partition is used to hold up to nine images of the switching application (de­pending on the size of the images) and one partition is used to hold up to 99 configuration set­ting files. The partition scheme of the flash is shown below:

Table 4-7: FLASH Partition Scheme (64MB)

Partition Size MTD

U-Boot Loader primary image (write protected) 256KB 11

U-Boot Loader secondary image, updatable (optional) 256KB 10

The kernel and initrd partitions labelled with ‘F’ contain factory default images which are known
to work properly on the AT8901. The factory default images cannot be updated using the CLI
commands described below.

AT8901 Software Description

The firmware update procedure is designed to provide a failsafe capability to update IPMC, ker­nel, initrd, application and configuration settings separately. Each combination of these com­ponents can be used as a startup configuration, though they must be compatible to each other.
Please always follow Kontron documentation for all your upgrades. Software versions provided
with an official release are known to work together.

In the following, the CLI commands to setup, change and activate startup configuration and the
CLI commands necessary to perform firmware upgrades are described. The CLI commands
described below are executed in the privileged mode of the CLI hierarchy, which is entered by
executing the ‘enable’ command. Please refer to the “AT8901/2/3 CLI Reference Manual“ for
more information regarding the CLI commands and the way to use them.

4.5.1 Startup Configurations

A startup configuration is a combination of a kernel, initrd, application image and configuration
files for base and fabric switch. The IPMC image is not part of the configuration and is updated
separately. Several configurations (up to 99) can be defined but only one is active at a time. To
display the currently available startup configurations, the CLI command ‘show’ is used.

(Base Fabric) #show startupconfig startup
ACT NR KERNEL SYSTEM APPLICATION BASE-CONFIG EXT-CONFIG

--- -- ------------ ------------ ------------- --------------- --------------­ F F BETA 6.09 F BETA 6.09 F BETA 6.09 F factory F factory
*A 01 A BETA 6.09 A BETA 6.09 02 BETA 6.09 01 standard 01 standard

(Base Fabric) #

In this example, two startup configurations are available. Startup configuration 01 is the cur­rently active configuration which is indicated by the ‘*’ in the first column. This configuration
consists of:

• Kernel BETA 6.09 which is located in kernel partition A

• Initrd BETA 6.09 which is located in initrd partition A.

• Application BETA 6.09 which is stored in slot 02 of the application partition.

• Base and fabric configuration files which are stored in slot 01 of the configuration parti­tion.

The user can define other startup configurations and combine images and configuration files
as needed. To set up a new startup configuration, it is necessary to change into the CLI’s con­figuration mode using the ‘configure’ command. In this mode, the ‘startupslot’ command is used
as shown in the following example:

(Base Fabric) (Config)#startupslot 3 config 1 application 2 initrd F kernel F

Successfully set startup slot 3
You may mark it active now and reboot to use the new configuration.

(Base Fabric) (Config)#exit

(Base Fabric) #

*A 01 A BETA 6.09 A BETA 6.09 02 BETA 6.09 01 standard 01 standard
03 F BETA 6.09 F BETA 6.09 02 BETA 6.09 01 standard 01 standard

A new startup configuration has been added to the list combining the software images given in
the previous command.

Warning!

It is not recommended to combine images from different releases.

The startup configuration created before can be deleted by entering exactly the same com­mand string preceeded by ‘no’:

(Base Fabric) (Config)#no startupslot 3 config 1 application 2 initrd F kernel F

The ‘show’ command can also be used to display available versions of kernel, initrd, applica­tions and configurations or all of them. The syntax is:

show startupconfig startup|kernel|initrd|application|config|all

The configuration mode is also used to activate one of the available startup configurations. The
syntax is:

startupslot 3 activate [once]

This command would activate the startup configuration 3 upon next system reset. The optional
parameter ‘once’ would start configuration 3 only once after the next system reset and start the
previously active configuration 1 on following resets. This is used to implement the failsafe up­grade procedure described below.

4.5.2 Updating Firmware

The firmware - except bootloader and IPMC image - is updated using the CLI. To get a reliable
and failsafe update procedure, the following precautions must be fulfilled:

• Three independent partitions each for kernel and root file system where one holds the
factory default system, one holds system A kernel and root file system and one holds sys­tem B kernel and root file system. The active system is either system A or system B, the
factory default serves as a backup in case an upgrade of either system A or B fails. See
the flash partition scheme shown above for more detail.

Page 4 - 19 AT8901 User Guide

AT8901 Software Description

• One Time Boot capability: After having updated the inactive kernel and root file system,
the new system has to be started by rebooting the board. In the case that the update has
installed an inoperable system which would cause the board to hang when booting, the
next board reset must restart the previous known good version of kernel and root file sys­tem. This is achieved by programming the bootloader environment appropriately.

• Redundant bootloader environment sectors: When the system is updated, the bootloader
environment must be changed to be able to start the updated version. The bootloader
environment sector is stored twice in flash, one active version and one backup version in
case the active version is deleted during update due to power loss or similar errors. In
this case, the redundant environment would cause the bootloader to start the previous
known good version of kernel and root file system.

A software update of the Hub Board is done by performing the following steps:

1. Download kernel, initrd and application images into the appropriate slots of the flash mem­ory. Ensure that the currently active images are not overwritten.

2. Select a configuration for base and fabric switch for the new software release. This can be done by choosing the factory default or by storing the running system configuration into flash.

3. Create a startup configuration by combining the slots with the update images and the con­figuration slots for base and fabric switch.

4. Activate the selected startup configuration for One Time Boot.

5. Restart the board.

6. Activate the new startup configuration permanently

A software release for the AT8901 consists of three software packages for kernel, initrd and
application software. The packages are tar archives containing an image of the software and a
MD5 checksum file for consistency check. The name of the package file is arbitrary but the file
names in the archive must not be altered.

When performing a firmware update, the software packages are loaded from a remote TFTP
server in the first step. This is done by means of the frontpanel FE port of the Hub board. To
load a software package via TFTP into a specified slot, the CLI command ‘download’ is used:

(Base Fabric) #download kernel tftp://192.168.50.5/kernel.pkg B

Downloading image, this may take a while...
Successfully transferred kernel image tftp://192.168.50.5/kernel.pkg to slot 2
You may mark it active now and reboot to use the new kernel image.

(Base Fabric) #

Page 4 - 20 AT8901 User Guide

AT8901 Software Description

This downloads the specified kernel package file via TFTP and writes the kernel image into the
kernel partition of the specified slot (B). The MD5 checksum of the kernel image is checked be­fore writing it into flash. The same procedure can be done with initrd and application packages.
It is important not to overwrite the slots containing the currently active software, otherwise the
One Time Boot mechanism does not make sense.

After the software images have been downloaded into flash, the configuration slots for base
and fabric switch must be selected. In case that no appropriate configuration for base and/or
fabric switch are available, the factory default configuration for base and fabric switch should
be used for the startup configuration of the new software release. Alternatively, the running
configuration settings of base and fabric switch can be stored on flash using the following CLI
command:

(Base Fabric) #copy system:running-config nvram:startup-config slot 3

This operation may take a few minutes.
Management interfaces will not be available during this time.

Are you sure you want to save? (y/n) y

Configuration Saved!

(Base Fabric) #

Instead of storing the configuration for ‘both’ base and fabric switch, ‘base-only’ or ‘ext-only’
might be given as parameters.

Finally, a startup configuration containing the slots of the new software release and the config­uration slots must be selected or a new startup configuration must be created as described
above. After this step has been completed, the startup configuration is activated only for the
next boot and the board is rebooted. This is done with the ‘startupslot’ CLI command in the con­figure mode:

(Base Fabric) (Config)#startupslot 3 activate once

This command enables the startup configuration 3 only for the next system restart. In the case
that the board hangs due to a corrupted software image, this will be detected and the board is
automatically rebooted with the previous known good startup configuration. This way, a failsafe
upgrade of the AT8901 software is possible.

To restart the board with the new startup configuration, the CLI command ‘reload’ is used:

(Base Fabric) (Config)#reload

If the new startup configuration is considered functional after the reboot, it must be activated
permanently, or else the one that is still active will be used again:

(Base Fabric) (Config)#startupslot 3 activate

AT8901 Software Description

4.5.3 Updating IPMI

Updating the IPMI firmware is different from updating the other software parts as updating is
done directly when invoking the download command. In the case that the update procedure
fails or the update image is corrupted, the IPMC will be able to restart all the same by means
of its rollback functionality. The IPMI software package file is stored in the result/ppc405/firm­ware path of the release directory tree. To update the IPMI firmware, the CLI command ‘down­load’ is used:

(Base Fabric) #download ipmifw tftp://192.168.50.5/ipmi.pkg

Flashing a new IPMI firmware will disable the IPMI Controller for some minutes.
