AT8901M Hardware Description RS232 Management Interface One RS232 interface (UART0) of the PowerPC 405 GPr is connected to the front panel RJ45 connector, the other one (UART1) is used as programming interface for IPMI. Table 3-4: Serial Port (RJ45) Pin Assignment Signal Pin RTS 1 DTR 2 TXD 3 GND 4 GND 5 RXD 6 DSR 7 CTS 8 1 8 External connection is established with a straight through Ethernet cable and a RJ45 (female) to SubD (female) adapter if required.
AT8901M 3.2 Hardware Description Base Switch The base switch is a Broadcom BCM56500 (full featured version) or BCM56300 (lite featured version) 24 port GbE multilayer switch that can operate in 10/100/1000 Mbps. It integrates advanced Layer 3 switching features for IPv4 and IPv6 routing. The BCM56500 also includes enhanced QoS support and jumbo packet line rate switching. The PPC controls the switch over a 32bit/66MHz PCI Interface.
AT8901M Hardware Description Base Interface Uplink The Hub Board supports four base interface uplinks to the front panel. The switch is connected to the RJ45 connectors with integrated status LEDs on the front panel via a 10/100/1000BASET quad PHY and two 10/100/1000BASE-T dual magnetics. GbE channels 0/1 to 0/4 of the switch map to uplink channels 1 to 4.
AT8901M Hardware Description 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).
AT8901M 3.3 Hardware Description AMC Bays Two AMC bays for standard or custom AMCs mid-size and single width are implemented with B+ connectors, which are compliant to the AMC.0 R1.0 specification. Following AMC Geographic Addresses are implemented: Table 3-9: AMC Bay Address AMC AMC Bay ID GA [2..0] IPMB-L Address 1 B1 UGU 7Ah 2 B2 UUG 7Ch The state of each GA signal is represented by G (grounded), U (unconnected) or P (pulled up to management power).

AT8901M Hardware Description 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.
AT8901M 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.
AT8901M 3.6 Hardware Description 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).

AT8901M 3.7.3 Hardware Description 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.
AT8901M 3.8 Hardware Description 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 and finally the Fabric 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).

AT8901M 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.

AT8901M 4.4 Software Description 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.
AT8901M 4.4.1 Software Description 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.

AT8901M 4.4.5 Software Description LEDs For LED positions on the front plate refer to Chapter 3, section 3.1.11., Display Elements. 4.4.5.1 Hot Swap LED (Blue LED) The AT8901M Hub Board supports a blue Hot Swap LED mounted on the front panel. This LED indicates when it is safe to remove the Hub from the chassis. The on-board IPMC drives this LED to indicate the hot swap state.
AT8901M 4.4.5.3 Software Description Health LED (ATCA LED2) Green LED Table 4-7: Health LED state LED state Description ON None of the health sensors is asserted Blinking At least one health sensor is asserted 4.4.5.4 Customer Definable LED (ATCA LED 3) This is an amber LED which can be used by a customer application. This LED can be controlled by PICMG 3.0 defined LED commands. 4.4.6 Hot Swap Process The AT8901M Hub Board has the ability to be hot-swapped in and out of a chassis.
AT8901M 4.5 Software Description Firmware Administration A running AT8901M 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 AT8901M firmware. The flash holding the software is divided into twelve partitions.
AT8901M 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.
AT8901M Software Description A new startup configuration has been added to the list combining the software image A and configuration file 1. 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 initrd A The ‘show’ command can also be used to display available versions of initrd and configurations or all of them.
AT8901M Software Description 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 AT8901M consists of one software package initrd, which includes kernel and application software). The package is a tar archive 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.
AT8901M Software Description 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 AT8901M software is possible.
