2.1Application

The Advanced Telecommunications Compute Architecture (AdvancedTCA) standards define open architecture modular computing components for carrier-grade, communications network infrastructure. The goals of the standards are to enable blade-based modular platforms to be:

•cost effective

•high-density

•high-availability

•scalable

These systems use a fabric I/O network for connecting multiple, independent processor boards, I/O nodes (e.g., line cards), and I/O devices (e.g., storage subsystem).

The MPCBL0001 SBC is designed per the AdvancedTCA Design Guide for High Availability, Switched Network Computing. Bulk storage for the system is connected through optional dual Fibre Channel interfaces. The MPCBL0001FXX SBC includes a Fibre Channel controller. The MPCBL0001NXX SBC does not have the Fibre Channel controller.

2.2Functional Description

This topic defines the architecture of the MPCBL0001 SBC through descriptions of functional blocks. Figure 1, “Block Diagram” on page 17 shows the functional blocks of the MPCBL0001 SBC. The MPCBL0001 SBC is a dual processor, hot-swappable SBC with backplane connections to dual Gigabit Ethernet star networks and dual Fibre Channel star arbitrated loops.

The SBC incorporates an Intelligent Platform Management Controller that monitors critical functions of the board, responds to commands from the shelf manager, and reports events.

Power is supplied to the MPCBL0001 SBC through two redundant -48 V power supply connections. Power for on-board hardware management circuitry is provided through a standby converter on the power mezzanine. This converter, along with all the other converters on the power mezzanine are fed by the diode OR'd -48 V supply from the backplane.

The SBC has provision for the addition of a PMC device and supports 32-bit and 64-bit transfers at 33 MHz and 66 MHz. The SBC also offers one USB and one service terminal interface. An overview of each block follows.

2.2.1Low Voltage Intel® Xeon™ Processor CPU-0 (U35), CPU-1 (U36)

The MPCBL0001 SBC supports up to two Low Voltage Intel® Xeon™ processors (see Figure 20, “Component Layout (#1)” on page 100 for locations). The Low Voltage Xeon processor incorporates Intel® NetBurst™ microarchitecture and a high-bandwidth Front-Side Bus, allowing performance levels that are significantly higher than previous generations of IA-32 family processors. The processors include the following features:

•2.0 GHz with a 400 MHz system bus

•512 Kbyte L2 cache

•Hyper-pipelined technology

•Advanced dynamic execution

•Execution trace cache

•Streaming SIMD (single instruction, multiple data) extensions 2

•Advanced transfer cache

•Enhanced floating point and multimedia engine

•Intel & OEM EEPROM and thermal sensor manageability features

•Supports single and dual processor configurations

•Throttling enabled for protection against high temperatures

The Low Voltage Xeon processor host bus utilizes a split-transaction, deferred-reply protocol. The host bus uses source-synchronous transfer of address and data to improve throughput at the 100 or 133 MHz bus frequency (depending on processor model). Addresses are transferred at 2X the bus frequency while data is transferred at 4X the bus frequency, resulting in peak data transfer rates up to 3.2 or 4.3 GBytes/s.

In addition to the NetBurst microarchitecture, the Low Voltage Intel Xeon processor includes a groundbreaking technology called Hyper-Threading Technology† (HT Technology). HT Technology improves processor performance for multithreaded applications or multitasking environments by supporting multiple software threads on each processor.

Low Voltage Intel Xeon processors require their package case temperatures to be operated below an absolute maximum specification. If the chassis ambient temperature exceeds a level whereby the processor thermal cooling subsystem can no longer maintain the specified case temperature, the processors will automatically enter a mode called Thermal Monitor to reduce their case temperatures. Thermal Monitor controls the processor temperature by modulating the internal processor core clocks, thereby reducing internal power dissipation, and does not require any interaction by the Operating System or Application. Once the case temperatures have reached a safe operating level, the processor will return to its non-modulated operating frequency. See the Low Voltage Intel Xeon processor datasheet, referenced in Appendix A, “Reference Documents”, for further details.

An optional ITP700 port connection is included to facilitate debug and BIOS/software development efforts. This JTAG connection to the processors utilizes voltage-signaling levels that are specific to the Low Voltage Xeon processor family. These levels must not be exceeded or processor damage may occur. Please refer to Intel document ITP700 Debug Port Design Guide, order number 249679-005 for additional information on the ITP connector pin definitions.

used. Even though the BIOS automatically sets the DMA mode/type, the OS could downgrade the DMA transfer mode. Check the operating system documentation to see what DMA mode is used by default and whether it is possible to change to a higher performance DMA mode.

2.2.2.3Intel® 82870P2 64-bit PCI/PCI-X Controller Hub 2 (U14, U24)

The two P64H2 devices provide the system’s high-performance PCI bus support. See Figure 20, “Component Layout (#1)” on page 100 for their locations. Each P64H2 component supports two independent, 64-bit, PCI/PCI-X interfaces. 32-bit/33 MHz and 64-bit/66 MHz PCI bus modes are also supported. Each PCI bus interface features:

• PCI-X 1.0 Specification compliance

• PCI Specification 2.2 compliance

• PCI-PCI Bridge Rev 1.1 compliance

• PCI Hot Plug 1.0 compliance

• I/O APIC supporting up to 24 interrupts (16 external pins)

• PCI peer-to-peer write capability between PCI ports

• SMBus target for Out-of-Band access to all internal PCI registers

Each of the two P64H2 devices (U14, U24) included on the MPCBL0001 SBC provides the bridge to two independent PCI bus connections, as shown in Table 1, “P64H2 Interfaces” on page 21.

	The two high-speed communications interfaces (Gigabit Ethernet and Fibre Channel) are located in
	separate P64H2 devices to maximize data throughput. A single HI-2 hub link connection from the
	P64H2 to the MCH provides a >1 Gbyte/s bandwidth back to memory and the processor System
	Bus.

2.2.3Memory (J8, J9, J10, J11)

Four DDR 266 DIMM sockets make up the memory subsystem. See Figure 20, “Component Layout (#1)” on page 100 for their locations. The MCH defines two memory channels operating in parallel to logically create a 144-bit wide memory data path. ECC is generated and checked across 128 bits of data, allowing for significant improvement in error correction.

Due to this architecture, DDR DIMMs must be installed in matched pairs. Memory DIMM configurations ranging from 512 MBytes to 8 GBytes in 512 MByte increments are supported.

2.2.3.1Memory Ordering Rule for the MCH

Platforms based on the E7501 chipset require DDR DIMMs to be populated in matched pairs in a specific order. Start with the two DIMMs furthest from the MCH in a “fill-farthest” approach (see Figure 2). This requirement is based on the signal integrity requirements of the DDR interface.

2.2.4.2Real-Time Clock

The MPCBL0001 SBC real-time clock is integrated into the ICH3. It is derived from a 32.768 KHz crystal with the following specifications:

•Frequency tolerance @ 25 ºC: ±20ppm

•Frequency stability: maximum of -0.04ppm/( ºC)2

•Aging F/f (1st year @ 25 ºC): ±3ppm

•±20ppm from 0-55 ºC and aging 1ppm/year

The real-time clock is powered by a 0.22F SuperCap* capacitor when main power is not applied to the board. This capacitor powers the real-time clock for a minimum of two hours while external power is removed from the MPCBL0001 SBC.

See Section 3.13, “Watchdog Timers (WDTs)” on page 64 for information about the real-time clock timers.

2.2.4.3Timer0 Capabilities

Timer0, integrated inside the ICH3, is an 8254 compatible timer. This timer is set up to generate a periodic waveform that creates the edge for the timer0 interrupt. The interrupt is received by the ICH3 APIC and communicated to the CPU(s).

MPCBL0001 provides a high-precision 14.318 MHz crystal clock source as the reference for the timer0 counters. To improve timing accuracy, the crystal used is a low-PPM, high-stability component with the following specifications:

•Frequency tolerance (25º C): ±10ppm

•Temperature characteristics (-10º C to +60º C): ±5ppm

•Aging: ±1ppm per year max

This timer does not operate when board power is removed.

2.2.4.4Gigabit Ethernet (U13)

The MPCBL0001 SBC implements two Gigabit Ethernet interfaces, each of which is routed to the fabric/switch slot through the backplane (J23, see page 85). There are no direct, external Ethernet ports included on the SBC board. Each Ethernet connection utilizes an 82546 Dual Gigabit Ethernet Controller, allowing support for 1000Mbits/s, 100Mbits/s and 10Mbits/s data rates.

The 82546 controller is optimized for designs using the PCI and the emerging PCI-X bus interface extension. The MPCBL0001 SBC has a 133 MHz PCI-X bus connection. The integrated physical layer circuitry (PHY) provides an IEEE 802.3 Ethernet Interface for 1000Base-T, 100Base-TX, and 10Base-T applications.

Features include:

•32/64-bit 33/66 MHz, PCI Rev 2.2 compliant interface

2.2.4.5Fibre Channel* (U23) - Optional

The QLogic* ISP2312 dual Fibre Channel controller is used for access to high-speed storage subsystems. It is routed through backplane connector P23.

See Figure 20, “Component Layout (#1)” on page 100 for its location.

This controller supports PCI and PCI-X bus interfaces. Burst mode master DMA transfers are utilized for efficient usage of bus bandwidth during data transfers, and 8, 16, and 32-bit accesses are supported as a PCI target. The controller appears as two independent Fibre Channel ports. A PCI function is assigned to each port in the device’s PCI configuration space. Functions 0 and 1 are used to configure FC ports 1 and 2, respectively.

ISP2312 features include:

•32/64-bit 33/66 MHz, PCI Rev 2.2 compliant interface.

•Host interface compliant with the PCI-X addendum, Rev 1.0a, from 50 to 133 MHz.

•Supports 64-bit addressing (addresses >32 bit initiate use of DAC address cycle).

•Efficient PCI bus master operation, supported by optimized internal DMA controller.

•Support for JTAG boundary scan.

•Supports IP as well as other protocols; however there are currently no plans to validate protocols other than SCSI_FCP.

Each Fibre Channel interface of the ISP2312 includes its own internal 16-bit RISC processor and external 7.5 ns synchronous SRAM memory for instruction code and data. Parity protection is provided on accesses to this memory. The SBC utilizes two 256 KByte (128Kx18) SRAMs, one for each port, for the ISP2312 memory requirements.

An external 256 x 16 non-volatile EEPROM is used to store system configuration parameters and PCI subsystem and subsystem vendor IDs. The first 128 bytes are used for function 0 parameters and the second 128 bytes are used for function 1.

2.2.5PMC Connector (J25, J26, J27)

The MPCBL0001 SBC supports one 64-bit, 66 MHz PMC slot. The PMC slot is connected to the second of two P64H2 hub controllers via PMC Connectors J25-J27. The PMC slot has an opening in the front panel of the SBC that exposes the I/O connectors of the add-in PMC card. PMC cards can only be added to or removed from this slot when the board is outside the system chassis. See Figure 20, “Component Layout (#1)” on page 100 for its location.

The PCI bus specification provides the means for backward compatibility with slower PMC cards (32-bit or 33 MHz) through the use of the M66EN pin. A PMC card that does not support 66 MHz operation grounds the M66EN pin when installed to inform the SBC hardware to provide a 33 MHz clock to this interface. Support for 32-bit only PMC cards is accomplished through the use of the REQ64#/ACK64# PCI bus protocol.

The PMC slot provided by the SBC connects the PCI VI/O voltage pins to +3.3 V. This requires use of PMC plug-in cards that support +3.3 V I/O signal levels. Only PMC plug-in cards designated “+3.3 V only” or “universal” voltage I/O are supported. The PMC plug-in location provides a key pin to prevent insertion of cards that do not meet this requirement. Note that +5 V power is still supplied to the PMC pins designated for +5 V connections. The PMC is allotted 1.5 A of current.

2.2.6Firmware Hub (U30, U33)

The MPCBL0001 SBC supports two 8Mbit (1 MByte) BIOS flash ROMs:

•Primary BIOS flash ROM (FWH0)

•Recovery BIOS flash ROM (FWH1)

The flash is allocated for BIOS and Firmware usage.

The SBC boots from the primary flash ROM under normal circumstances. During the boot process, if the BIOS (or IPMC) determines that the contents of the primary flash ROM are corrupted, a hardware mechanism is available to change the flash device select logic to the recovery flash ROM. See Section 2.2.6.3, “Flash ROM Backup Mechanism” on page 26 for more information.

Each flash component has a separately write-protected boot block that prevents erasure when the device is upgraded.

Contents

Flash ROM BIOS updates can be performed by an end user or a network administrator over the LAN. The system should complete booting to an OS, MS-DOS* or logon to Linux* as root user. The system should have a local copy of the flash program and the BIOS data files or have the capability to copy the flash program and BIOS data files onto a local drive via the network. The flash program has a command line interface to specify the path and the file name of the BIOS data files. After completing the BIOS ROM update the user should shutdown and reset the system to let the new BIOS ROM take effect. See Section 7.7, “BIOS Updates” on page 112 for more information.

2.2.6.1FWH 0 (Main BIOS)

BIOS execute code off this flash and perform checksum validation of its operational code. This checksum occurs in the boot block of the BIOS. The BIOS image is also stored in FWH0. When user performs BIOS update, the BIOS image will be stored in FWH 0 only. FWH0 will also store the factory default CMOS settings user configured CMOS settings.

1.When user "Load optimal defaults" from the BIOS setup screen, it restores the factory default by copying the "Factory Default" settings from FWH0 to ICH3 (CMOS).

2.When user "Save custom defaults" from the BIOS setup screen, the changes will be made to the CMOS settings on ICH3 and then copied from ICH3 to FWH0.

3.When user "Load custom defaults" from the BIOS setup screen, the "custom" CMOS settings are copied from FWH0 to ICH3.

2.2.6.2FWH 1 (Backup/Recovery BIOS)

FWH 1 stores the recovery BIOS. In the event of checksum failure on the Main BIOS operational code, BIOS will request BMC to switch FWH, so that the board will be able to boot up from FWH1 for recovery.

User is able to boot up the board from FWH1 by executing an OEM IPMI command as well (see Section 3.7.1, “Reset BIOS Flash Type” on page 49).

2.2.6.3Flash ROM Backup Mechanism

The on-board Intelligent Platform Management Controller (IPMC) manages which of the two BIOS flash ROMs is used during the boot process. The IPMC monitors the boot progress and can change the flash ROM selection and reset the processor.

The default state of this control configures the primary Firmware Hub (FWH) ROM device ID to be the boot device; the secondary FWH is assigned the next ID. The secondary FWH responds to the address range just below the primary FWH ROM in high memory.

The Intelligent Platform Management Controller sets the ID for both FWH devices. Boot accesses are directed to the FWH with ID = 0; unconnected ID pins are pulled low by the FWH device. In this way the IPMC may select which flash ROM is used for the boot process.

Refer to Section 3.7.1, “Reset BIOS Flash Type” on page 49 for a description of how to do this manually.

2.2.7Onboard Power Supplies

The main power supply rails on the MPCBL0001 SBC are powered from dual-redundant -48 V power supply inputs from the backplane power connector (P10). There are also dual redundant, limited current, make-last-break-first (MLBF) power connections. See Figure 20, “Component Layout (#1)” on page 100 for their location.

2.2.7.1Power Feed Fuses

As required by the PICMG 3.0 Specification, the MPCBL0001 SBC provides fuses on each of the -48V power feeds and on the RTN connections as well. The fuses on the return feeds are critical to prevent overcurrent situations if an ORing diode in the return path fails and there is a voltage potential difference between the A and B return paths.

2.2.7.2ORing Diodes and Circuit Breaker Protection

The two -48 V power connectors are OR’d together. A current limiting FET switch is connected between the OR’d -48 V and the primary DC-DC converters. The FET switch provides three functions:

•A mechanism to electrically connect/disconnect the SBC to/from the two -48 V inputs.

•A soft-on function.

•An over-current circuit breaker feature.

2.2.7.3-48 V to +12 V Converter

This converter provides DC isolation between the -48 V and -48 V return connections and all of the derived DC power on the MPCBL0001 SBC. Its output is connected to the SBC’s +12 V power rail. The converter supplies a maximum of 9 A of current. The converter is enabled/disabled by the onboard IPMC.

2.2.7.4-48 V to +5 V/+3.3 V Converter

This converter provides DC isolation between the -48 V and -48 V return connections and all of the derived DC power on the MPCBL0001 SBC. Its output is connected to the SBC’s +5 V and 3.3 V power rails. The converter supplies a maximum of 9 A of +5 V current and 9 A of +3.3 V current. The converter is enabled/disabled by the onboard IPMC.

2.2.7.5Processor Voltage Regulator Module (VRM)

The Voltage Regulator Module (VRM) provides core power to the two Low Voltage Xeon processors. The input to the VRM is connected to the +12 V power rail.

See Figure 20, “Component Layout (#1)” on page 100 for its location.

The VRM controller is designed to support multiple processor core voltages selected by the voltage identification (VID) pins on the processor. Logic provided on the SBC ensures that the VRM is not enabled if the two processors request different VID codes. In addition, the VRM is disabled until all other voltage converters indicate “power good.” The voltage regulator module is designed to support up to two 43 W (TDP - Thermal Design Power) processors.

Note: The +5 VSB power rail only needs to supply at least 4.0 V to properly power any circuitry that uses the +5 VSB rail when the payload power (i.e., processors, ethernet controller, etc.) is not turned on. Any alerts from the +5 VSB sensor when the system is not in the M4, M5, or M6 states should be ignored.

2.2.7.6IPMB Standby Power

This converter provides DC isolation between the -48 V and -48 V return connections and all of the derived DC power on the MPCBL0001. Its output is connected to the IPMB and standby +5 V power rail of the SBC. The converter supplies a maximum of 1.5 A of +5 V current. A +3.3 V management voltage is derived from the IPMB power by means of a linear regulator circuit and is used to power most of the IPMC functions. Standby power is derived from the -48 V rails and is always available on the SBC unless the overall system power rail (-48 V) is shut down.

Hardware Management Overview

3

The Intelligent Platform Management Controller (IPMC) is an Intel-designed baseboard management controller device manufactured by Philips Semiconductor* for Intel.

The high-level architecture of the baseboard management for MPCBL0001 is represented in the block diagram below.

	Memory

The main processors communicate with the IPMC using the Keyboard Controller Style (KCS) interface. Two KCS interfaces are available for the BIOS to communicate to the IPMC. BIOS uses SMS interface for normal communication and SMM interface when executing code under systems management mode (SMM). The base address of the LPC interface for SMS is 0xCA2 and 0xCA4 for SMM operation. Besides that, the BIOS is able to communicate with the IPMC for POST error logging purposes, fault resilient purposes, and critical interrupts via the KCS interface.

The memory subsystem of the IPMC consists of a flash memory to hold the IPMC operation code, firmware update code, system event log (SEL), and a sensor data record (SDR) repository. RAM is used for data and occasionally as a storage area for code when flash programming is under execution. The field replacement unit (FRU) inventory information is stored in the nonvolatile memory on ADM1026. The flash memory can store up to 64 KBytes of SEL events and SDR information, while the ADM1026 can store up to 512 bytes of FRU information. Having the SEL and logging functions managed by the IPMC helps ensure that ‘post-mortem’ logging information is available even if the system processor becomes disabled.

Contents

The IPMC provides six I2C bus connections. Two are used as the redundant IPMB bus connections to the backplane while another one is used for communication with the ADM1026. The remaining buses are unused. 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 SBC board. Where possible, the IPMC activates the redundant IPMB bus to re-establish system management communication to report the fault.

The onboard DC voltages are monitored by the ADM1026 device, manufactured by Analog Devices. The IPMC queries the ADM1026 over a local system management I2C bus. The ADM1026 includes voltage threshold settings that can be configured to generate an interrupt to the IPMC if any of the thresholds are exceeded.

To increase the reliability of the MPCBL0001 SBC, a watchdog timer is implemented, whereby it strobes an external watchdog timer at two-second intervals to ensure continuity of operation of the board’s management subsystem. If the IPMC ceases to strobe the watchdog timer, the watchdog timer isolates the IPMC from the IPMBs and resets the IPMC. The watchdog timer expires after six seconds if strobes are not generated, and it resets the IPMC. Detailed information on the watchdog timer configuration can be queried using standard IPMI v1.5 watchdog timer commands. The watchdog timer does not reset the payload power.

3.1Sensor Data Record (SDR)

Sensor Data Records contain information about the type and number of sensors in the baseboard, sensor threshold support, event generation capabilities, and the types of sensor readings handled by system management firmware.

The MPCBL0001 management controller is set up as a satellite management controller (SMC). It does support sensor devices, whose population is static by nature. SDRs can be queried using Device SDR commands to the firmware. Refer to Section B, “List of Supported Commands (IPMI v1.5 and PICMG 3.0)” on page 189 for the list of supported IPMI commands for SDRs. Hardware sensors that have been implemented are listed below.

NOTE: The PROCHOT signal is a discrete signal but it is treated as a threshold sensor so that it can have a Sensor Type of Temperature. IPMI does not have a discrete sensor type for temperatures. The advantage of the PROCHOT sensor acting as a temperature sensor is that the CMM can recognize events from this sensor as temperature events and adjust fan speed accordingly.

3.2System Event Log (SEL)

The SEL is the collection of events that are generated by the IPMC. Event logs are stored in nonvolatile memory. This resides on the board and allows better tracking of error conditions on the baseboard when it is moved from chassis to chassis. Having the SEL and logging functions managed by the IPMC helps ensure that post-mortem logging information is available should a failure occur that disables the systems processor(s). In the MPCBL0001, flash memory for IPMI firmware can store up to 3276 SEL entries. Management software running on the host processor is responsible for ensuring that SEL storage has sufficient space for SEL logging. Events are normally forwarded to shelf manager and logged to SEL on the board. If SEL storage on the board is full, new events are forwarded to the Shelf Manager but are not logged in to SEL on the board.

A set of IPMI commands (see Table 108, “IPMI 1.5 Supported Commands” on page 189) allows the SEL to be read and cleared and allows events to be added to the SEL. The IPMI commands used for adding events to the SEL are Platform Event Message, Add SEL entry, and Partial Add Entry. Table 3, “SEL Events Supported by the MPCBL0001 SBC” on page 33 lists supported SEL events. Event Messages can be sent to the IPMC via the IPMB. This provides the mechanism for satellite controllers to detect events and log them into the SEL.

3.2.1Temperature and Voltage Sensors

Temperature and voltage readings are monitored by ADM1026. They are critical sensors that ensure the MPCBL0001 is operating at its predefined threshold limits. The sensors are categorized as follows:

•Lower Non-Critical

•Lower Critical

•Upper Non-Critical

•Upper Critical

If the lower critical or upper critical threshold is exceeded, it raises a major alarm. If the lower noncritical or upper non-critical threshold is exceeded, it raises a minor alarm.

Only critical thresholds which are exceeded turn the Health LED solid red. However, for any events above, IPMC forwards the events to the shelf manager to log it into shelf manager’s SEL.

3.2.2Processor Events

The processor asserts IERR as the result of an internal error. A thermal trip error indicates the processor junction temperature has reached a level where permanent silicon damage may occur. Upon THERMTRIP assertion, the IPMC powers down the boards.

3.2.3DIMM Memory Events

The MCH (E7501) instructs the ICH3 to report memory parity errors via SMI#. The SMI handler extracts the error information (address) from the DRAM error registers in the MCH and logs it into the SEL. The KCS interface performs error reporting to IPMC. BIOS sends a platform event message with the appropriate data to the IPMC, which logs the event to SEL and forwards the event to the Shelf Manager. Correctable memory errors generate an SMI and are logged into SEL. Normally, a board with non-correctable errors is likely to hang as the multi-bit error may cause the CPU to execute corrupted instructions. If the CPU executes corrupted instructions before executing the code to log the event, then this event will not be logged in the SEL.

3.2.4System Firmware Progress (POST Error)

The BIOS is able to log both POST and critical events to the IPMC error log. (Refer to Table 89, “BIOS Error Messages” on page 138.)

3.2.5Critical Interrupts

In general, the system BIOS is capable of generating requests on the KCS interface to communicate with the IPMC for error logging, fault resilience, critical interrupts and reading/ writing inventory CPUs and RAM information to the IPMC. Two LPC interfaces are available for the BIOS to communicate to the IPMC. The BIOS uses the SMS interface for normal communication with the IPMC and the SMM interface when executing code under SMM mode.

PCI errors implemented in the MPCBL0001 are handled as follows:

1.The MCH(E7501) sends a parity error/system error (PERR/SERR) message over the hub interface to the ICH3 notifying it that an error occurred.

2.The ICH3 generates an SMI# interrupt when it receives a PERR/SERR message.

3.The SMI handler checks the error status registers of CPU/MCH until it identifies the source and type of the error.

4.The handler sends a message to the IPMC via the KCS interface, causing it to log the error in the IPMC’s event log. IPMC then forwards the event to Shelf Manager to log it into Shelf Manager SEL.

3.2.6System ACPI Power State

MPCBL0001 is targeted to support ACPI functionality, with support for the sleep states S0, S4 & S5. On assertion of ICH3_SLP_S5# and ICH3_SLP_S3# GPIOs, IPMC sends out a hot-swap event message to the shelf manager requesting deactivation. On successful reception of a deactivation message from the shelf manager, the FRU enters M1 power state and remains in this state.

Under conditions where an ACPI enabled operating system is in S4/S5 sleep state, the chipset could deassert ICH3_SLP_S5# and ICH3_SLP_S3# GPIOs requiring the IPMC to attempt AdvancedTCA power state transition to M4 state (through M2, M3).

ACPI capabilities of an operating system are communicated by BIOS to the IPMC at initialization. An OEM style IPMI command is sent by BIOS for this purpose. This command (SetACPIConfig ; NetFn: 30h, command: 83h) is sent by BIOS every time an operating system is initialized. The IPMC firmware defaults to no ACPI until this command is received with proper data in the request to indicate the OS is either ACPI enabled or disabled. For obvious reasons, this command is only executable over SMS channel.

3.2.7IPMB Link Sensor

The MPCBL0001 provides two IPMB links to increase communication reliability to the shelf manager and other IPM devices on the IPMB bus. These IPMB links work together for increased throughput where both busses are actively used for communication at any point. 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 changes, the events are written to the MPCBL0001 SEL. 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 signify the failure of a bus or, conversely, the recovery of a bus.

3.2.8FRU 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.

3.2.9CPU Failure Detection

A CPU failure during runtime or POST will have better error handling: a SEL event notification will be generated if either one of the CPUs fails to power up, and the Health LED will turn red.

1.An FRB3 timer (30 seconds) was implemented to detect the failure of the CPUs to boot. This also now implements offset 04h in the CPU 0 Status sensor. When asserted, it will generate an event and set the Health LED to red.

2.The SMI line is now checked for a long (10 second) assertion that indicates a severe hardware failure around the CPUs during runtime. As a result, a new discrete sensor has been added (SMI Timeout) that will assert when the SMI line stays asserted too long.

Refer to Table 9 for the SEL events associated with FRB3 timer timeout and SMI Timeout assertion.

3.2.10Port 80h POST Codes

When there is an FRB3 failure, the event message sent from the CPU Status sensor with sensor type code 07 provides the last Port 80 code byte written by the BIOS. This information is contained in Data Byte 3 of the event message.

Example:

To decode Port 80 data from SEL event when a board is booted without memory, refer to the following method.

SEL EVENT - ID:0DD8(Tue Jan 25 18:45:20 2005) Gen:8E Type:07 No:50 Dir:6F D1:64 D2:6F

D3:E1

The values shown in bold above convey the following information:

•The sensor type is 07. This refers to the processor.

•Event data 1, bit 0-3 is 4. This refers to an FRB3/processor startup or initialization failure (the CPU did not start).

•Event data 3 is E1. This refers to the last Port 80h POST codes before the board hangs.

Refer to the tables in Section 9.2 for descriptions of the Port 80h POST codes.

Note: At any time when a board hangs, you may also use an OEM IPMI command to query the Port 80 POST codes. For the command syntax, refer to Section 3.7.7, “Get Port80 Data” on page 52.

3.3Field 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 MPCBL0001 includes data describing the MPCBL0001 board as per PICMG 3.0 Specification requirements. Additional multirecords will be added for the BIOS to write CPU information, BIOS version number, and PMC information to FRU data correctly. This information is retrieved by shelf manager (ShMC), enabling reporting of board-specific information through an out-of-band mechanism.

Following are the definitions for the multirecord implemented by the firmware as part of FRU data.

3.4E-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.

Upon management power-on, the firmware sets the Fibre Channel ports to front panel by default. 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 Fibre Channel 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.

If user Fibre Channel selection is to the front, the firmware maintains the Fibre Channel ports to the front panel regardless of the shelf manager’s granting or rejecting of E-keys for the board.

Table 12 on page 46, describes the:

•Connections to base and fabric interfaces on the MPCBL0001 board for E-keying purposes.

•Link descriptor list for the two Gigabit Ethernet channels connected to the base interface and the two Fibre Channels on the fabric interface.

3.5IPMC 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.Sets up the internal real-time operating system (RTOS).

3.Performs a checksum of the operational code.

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

46	Technical Product Specification
	Order #273817

Intel NetStructure® MPCBL0001 High Performance Single Board Computer

Contents

When the firmware is commanded to enter firmware (FW) update mode, the operational code uses a special branch, Software Interrupt, to jump to the FW update code in the boot block. Once in FW update mode, the update code is copied into RAM, then the firmware jumps to the code in RAM to execute. The FW update code cannot execute out of flash while the flash is being updated.

3.6IPMC Firmware Upgrade Procedure

MPCBL0001 firmware is upgraded using either of two methods, the KCS interface or the IPMB (RMCP) interface.

3.6.1IPMC Firmware Upgrade Using KCS Interface

The KCS interface is the communication mechanism between the host processor on the MPCBL0001 and the IPMC controller. A firmware update utility is available. It takes a hex file to be updated as input from the command line. It can also verify that updates are completed successfully by reading back data written to the flash memory. Typically, it takes the utility around two minutes to complete the update over the KCS interface. After the firmware update is

completed, the controller goes through a reset and boots up with the new firmware. The host processor is not reset when going through a firmware update, so the operating system and applications running on the host processor are not interrupted.

Please refer to the latest IPMC firmware release notes for the upgrade procedure. The upgrade procedure, utility, and upgraded firmware are part of the IPMC firmware release package, which can be downloaded from the Intel web site at http://www.intel.com/design/network/products/cbp/ atca/index.htm.

IPMI Specification v1.5 defines Remote Management Control Protocol (RMCP). Version 1.5 adds features for layering commands through virtual networks like Ethernet.

The IPMC firmware that needs to be upgraded is loaded to client utility software on the RMCP client. The RMCP client uses the RMCP protocol carrying embedded IPMI messages to send to the RMCP Server running in the CMM. The RMCP server decodes the RMCP package and forwards the IPMI messages to the SBC.
