The Intel

Server Chassis SR2500 is a 2U server chassis that is designed to support the Intel

Server Board S5000PAL. The server board and the chassis have features that are designed to support the high-density server market. This chapter provides a high-level overview of the chassis features. Greater detail for each major chassis component or feature is provided in the following chapters.

The chassis differs from previous generation products in that the majority of cables have been removed from the system and in their place are a series of board-to-board interconnects. The benefits of using board-to-board interconnects are simplification of platform integration and improved airflow for more reliable cooling.

A second significant change from the previous generation is the introduction of the mid-plane circuit board. There are two options for the mid-plane circuit board: the first option provides

SAS RAID support. The second option is a passive SATA/SAS mid-plane that can be used with either the SATA only connectors from the server board, or SATA/SAS connectors from an addin card.

The complete system includes the use of several system boards which are used as internal interconnects and provide feature accessibility. The following provides a brief description for each.

• Bridge Board – PCB used to route signals from the server board to the mid-plane and control panel boards.

• Mid-plane – A PCB used to determine the desired hard drive interface for the system.

Two mid-plane options are available for this system: o Active SAS/SAS RAID – cable less solution with onboard SAS controller o Passive SATA – cabled to SATA ports on the server board or from add-in adapter.

• Backplane – Hot swap backplane capable of supporting both SATA and SAS hard drives.

• Riser Cards – PCI riser cards used to provide up to five add-in card slots to the system.

Available riser card options for this system include: o Low profile, two slot PCI Express* o Full height, three slot PCI-X* (passive) o Full height, three slot PCI-X (active) with onboard PXH PCI bridge chip o Full height, two PCI Express slots + one PCI-X slot

The chassis is offered with two system cooling options. The first option is a three fan solution providing sufficient airflow to maintain internal system thermal requirements when the external ambient temperature remains within specified limits. The second option is a 5+1 fan configuration. Refer to section 3.2 for details. Should a single fan failure occur, this option provides support for hot-swap fans and fan redundancy.

In addition to the system fan options, each power supply module installed provides two additional non-redundant fans which pull air from inside the chassis out the back.

The chassis provides support for a lockable front bezel which prevents unauthorized access to the system control buttons and hard drives. In addition, a chassis intrusion switch is provided allowing server management software to monitor removal of the top cover from the chassis.

1.10 Rack and Cabinet Mounting Options

The chassis was designed to support 19” wide by up to 30” deep server cabinets. The chassis supports three rack mount options: o A fixed mount relay rack / cabinet mount kit (Product order code - AXXBRACKETS ) which can be configured to mount the system into either a 2-post rack or 4-post cabinet o A tool-less full extracting slide rail kit (Product order code – AXXHERAIL) designed to support an optional cable management arm (Product order code – AXXRACKCARM). o A basic slide rail kit (Product order code – AXXBASICRAIL) designed to mount the chassis into a standard (19” by up to 30” deep) EIA-310D compatible server cabinet.

1.11 Front Bezel Features

The optional front bezel is made of molded plastic and uses a snap-on design. When installed, its design allows for maximum airflow to maintain system cooling requirements.

TP02100

Figure 10. Optional Front Bezel

Separate front bezels are available to support systems that use either a standard control panel or the Intel

Local Control Panel with LCD support.

When the standard control panel is used, light pipes on the backside of the front bezel allow the system status LEDs to be monitored with the front bezel in the closed position. The front bezel lock is provided to prevent unauthorized access to hard drives, peripheral devices and the control panel.

Revision – 1.00

The power sub-system of the chassis consists of an integrated Power Distribution Module

(PDM), a power module enclosure, and support for up to two 750 Watt power supply modules.

The power sub-system can be configured to support a single module in a 1+0 non-redundant configuration, or dual modules in a 1+1 redundant power configuration. In a 1+1 configuration, a single failed power module can be hot-swapped with the system running. Either configuration will support up to a maximum of 750 Watts of power.

This chapter provides technical details to the operation of the power supply module and power sub-system. For additional information refer to the Intel

Server Chassis SR2500 AC Power

Supply Specification and the Intel

Server Chassis SR2500 Power Distribution Module

Specification.

2.2 Single Power Supply Module Population

In single power module configurations, server management firmware requires that the power supply module be populated in the bottom power module slot. The non-operating slot must have the power supply blank installed.

AF000023

Figure 14. Power Supply Blank

Configuring a single power supply module in the top location will cause the server management firmware and BIOS to generate a system error during POST and the error will be reported to the

System Event Log (SEL).

2.3 Handle and Retention Mechanism

Each power supply module includes a handle for module insertion to or removal from the module enclosure. Each module has a simple retention mechanism to hold the power module in place once it is inserted. This mechanism will withstand the specified platform mechanical shock and vibration requirements. The tab on the retention mechanism is colored Green to indicate it is a hot-swap touch point. The latch mechanism is designed to prevent insertion or removal of the module with the power cord plugged in. This will aid the hot-swapping procedure.

Hot-swapping a power supply module is the process of extracting and re-inserting a power supply module from an operating power system. During this process the output voltages shall remain within specified limits. Up to two power supply modules may be on a single AC line.

The power supply module can be hot-swapped by the method listed below.

Extraction: on removal, the power cord is unplugged first, and then the power module is removed. This can be done in standby mode or power-on mode.

Insertion: The module is inserted first, and then the power cord is plugged in. If powered off, the system and the power supply will power on into standby mode or power-on mode.

2.5 Airflow

Each power supply module incorporates two non-redundant 40mm fans for self cooling and partial system cooling. The fans will provide no less than 10 CFM airflow through the power supply when installed in the system and operating at maximum fan speed. The cooling air will enter the power module from the PDB side (pre-heated air from the system).

Cooling Subsystem Intel® Server System SR2500AL

Several components and configuration requirements make up the cooling sub-system of the chassis. These include the system fan module, the power supply fans, air baffles, CPU air duct, and drive bay population. All are necessary to provide and regulate the air flow and air pressure needed to maintain the system’s thermals when operating at or below maximum specified thermal limits. See Table 55. System Environmental Limits.

Two system fan assembly options are available for this chassis. The first option is a nonredundant three fan solution providing sufficient airflow to maintain internal system thermal requirements when the external ambient temperature remains within specified limits. The second option is a redundant fan solution. Three parallel sets of fans are arranged in series to provide redundant cooling in the event of a single fan failure. Each cooling option utilizes two fan types: a 60mm variable speed fan and an 80mm variable speed fan.

The chassis uses a variable fan speed control engine to provide adequate cooling for the system at various ambient temperature conditions, under various server workloads, and with the least amount of acoustic noise possible. The fans operate at the lowest speed for any given condition in order to minimize acoustics. The Baseboard Management Controller (BMC) integrated on the Intel

Server Board S5000PAL is used for the variable fan speed control function. The controller monitors selective component temperatures and the ambient temperature, as well as each fan’s RPM to determine the necessary airflow. The BMC sets the fan speeds to the appropriate RPM in order to maintain proper cooling. The BMC controller will also log errors into the System Event Log (SEL) when temperature sensors exceed their safe operating ranges, or if any of the fans fail to operate at safe airflow speeds. In the event of a fan failure, the BMC will boost the remaining fans to compensate for the lost air flow. A chassis with redundant fans can continue to operate in this degraded condition while the non-redundant chassis may not. If the cooling is not sufficient under a failed fan condition, the system will eventually shutdown to protect itself from thermal damage.

The system fan module has been designed for ease of use and has support for several management features that can be utilized by the server board management system.

• The fan module houses two different fan sizes. System fans 1 and 2 use an 80mm fan, while system fan 3 uses a 60mm fan.

• Each fan is designed for tool-less insertion to or removal from the fan module housing.

Note: The fans are NOT hot-swappable. The system must be turned off in order to replace a failed fan.

• Each fan within the module is capable of supporting multiple speeds. If the internal ambient temperature of the system exceeds the value programmed into the thermal sensor data record (SDR), the BMC firmware will increase the speed for all the fans within the fan module.

• Each fan connector within the module supplies a tachometer signal that allows the BMC to monitor the status of each fan. If one of the fans should fail, the remaining fans will increase their rotation and attempt to maintain the thermal requirements of the system.

• Each fan within the module is equipped with a failure LED. In the event of a fan failure, the failure LED on the failing fan can be illuminated by server management.

3.3 Air Flow Support

To control airflow within the system, the chassis uses an air baffle and a CPU air duct to isolate and direct airflow to three critical zones: the power supply zone, the full height PCI riser zone, and the CPU/memory/low profile PCI riser zone.

3.3.1 Power Supply Zone

An air baffle is used to isolate the air flow of the main system board zones from the zone directly behind the power supply. As the power supply fans pull pre-heated air through the power supply from inside the chassis, the zone behind it must remain as cool as possible by drawing air from the leftmost drive bays only.

3.3.2 Full Height Riser Zone

The full height riser zone is the area between the power supply assembly and the full height riser card of the riser assembly. The air flow through this area is generated by system fan 3 of the fan module in a non-redundant fan configuration. In a redundant fan configuration, the air flow for this zone is provided by system fans 5 and 6. Air is drawn from the drive bay area through the fan and pushed out of the system through ventilation holes the back side of the chassis.

3.3.3 CPU / Memory / Low Profile PCI Zone

The CPU / memory / low profile PCI zone is the area between the low profile riser card of the riser assembly and the right chassis wall. In a non-redundant fan configuration, the air flow for this zone is generated by system fans 1 and 2 of the fan module. In a redundant fan configuration, the air flow for this zone is provided by system fans 1, 2, 3 and 4. Air is drawn from the drive bay area, through the fans, directed through the CPU air duct, and out through ventilation holes on both the back wall and rear side wall of the chassis.

The CPU air duct is used to direct air flow through the processor heat sinks for both single and dual processor configurations. For single processor configurations, a flexible air baffle is attached to the air duct as shown in the following diagram.

AF000048

Figure 19. CPU Air Duct with Air Baffle

Operating a single processor configuration without the air baffle installed will result in the processor over heating and may cause the system to shutdown.

3.4 Drive Bay Population

To maintain the proper air pressure within the system, all hard drive bays must be populated with either a hard drive, or drive blank.

System Board Interconnects

The chassis incorporates several design changes from the previous generation Intel 2U server chassis, resulting in improved cable routing. System boards within the chassis include the midplane, bridge board, hot-swap backplane, and control panel. This chapter describes the interconnect features of each, and defines the pin-outs for each of their connectors. Functional details of each system board are described in later chapters.

4.1 Mid-plane

The mid-plane is new to this generation of Intel high density server platforms. Its design and use, along with that of the bridgeboard and hot-swap backplane, improve cable routing within the system. The mid-plane is the key system board of the chassis. It serves as the primary interface between the server board, hot-swap backplane, and control panel. Two mid-planes are offered for this chassis: a passive SATA/SAS, and an active SAS/SAS RAID.

The passive midplane is a simple pass through from the backplane to the SATA connectors on the baseboard or SAS/SATA connectors on an add-in card.

The following diagram shows the location for each connector found on the passive mid-plane board.

4.2 Bridge Board

The chassis utilizes a bridge board to route signals from the server board to the mid-plane board. The bridge board carries signals for three USB ports, SSI front panel control signals, video, various I2C buses, fan control signals, and a PCIe* x4 bus for SAS controller function.

See Table 19. 120-pin Server Board-to-Mid-plane Bridge Board Connector Pin-out.

4.3 Hot-Swap SATA/SAS Backplane

The hot swap backplane provides support for both SAS and SATA hard drives. There are no hard drive cables that connect to the backplane. All hard drive control signals are routed from the mid-plane board which plugs directly into the backplane.

The IDE Optical drive assembly includes an interposer board which plugs into the back of the optical drive. The interposer board is a card-edge type card that eliminates the need for cable connections. As the drive assembly is inserted into the drive bay, the edge connector is blind mated to a slot connector on the backplane.

The interposer board has two connectors. The first connector is the industry standard 50-pin

IDE interface used by all slim-line optical devices. The second connector is the card edge used to connect directly to the hot-swap backplane board.

The USB floppy drive assembly includes a USB cable which plugs into the back of the USB floppy drive and is then routed to the backplane’s 4-pin USB connector J2A1 (See Table 35.

USB Floppy Drive Connector (J2A1).

Note: The optional internal USB floppy drive accessory kit (product order code –

AXXUSBFLOPPY) includes a slim-line USB floppy drive, a USB cable, and mounting hardware to install the drive into either the slim-line drive bay or one of the hard drive bays.

5.2 Hard Drive Bays

The chassis can be configured to support up to 6 1 hot-swap 3.5” x1” SAS or SATA hard disk drives. Hard drives are mounted to hot-swap drive trays for easy insertion to or extraction from the drive bay.

5.2.1 Hot-swap Drive Trays

Each hard drive must be mounted to a hot-swap drive tray, making insertion and extraction of the drive from the chassis very simple. Each drive tray has its own dual purpose latching mechanism which is used to both insert/extract drives from the chassis and lock the tray in place. Each drive tray supports a light pipe providing a drive status indicator, located on the backplane, to be viewable from the front of the chassis.

Peripheral and Hard Drive Sub-System Intel® Server System SR2500AL

New to this generation of high density server platform is the concept of the mid-plane. The midplane is the interconnect between the server board and both the hot-swap backplane and control panel. It is also used to determine which hard drive technology is to be supported. Two different Mid-plane options are available for this platform 1) a passive mid-plane capable of supporting SATA ports from the server board or SAS using ports from an add-in card; 2) an active SAS / SAS RAID mid-plane. This section will describe the hard drive interface support of each of the mid-plane boards.

The passive mid-plane is used as an interconnect, routing drive control signals from either the on-board SATA ports of the baseboard or SAS/SATA ports from an add-in card to the hot-swap backplane. The hard drive controller signals are cabled to the mid-plane which then routes the signals to the hot-swap backplane through two edge connectors that plug directly into it. See

Table 22. Mid-plane-to-Backplane Card Edge Connector #1 Pin-out and Table 23. Mid-plane-to-

Backplane Card Edge Connector #2 Pin-out.

SAS /SAS RAID Support

The active mid-plane is used to provide SAS / SAS RAID support. It has integrated on to it an

Intel IOP80333 IO processor and an LSI* LSLSAS1068 3Gb/s SAS controller. Together they provide support for up to six SAS drives in this chassis. By default, this mid-plane option provides software RAID levels 0, 1, and 10 utilizing Intel

Embedded RAID Technology II. With the installation of optional RAID enablement devices, the mid-plane can support hardware RAID levels 0, 1, 5, 10, and 50. The mid-plane attaches to the hot-swap backplane by two card edge connectors which eliminates the need for any hard drive cables. The following sub-sections describe the board level SAS / SAS RAID functionality.

5.4.2.2 x4 PCIe* Card Edge Interfaces

Two x4 PCIe* card edges are used to connect the active mid-plane to the hot-swap backplane.

See Table 22. Mid-plane-to-Backplane Card Edge Connector #1 Pin-out and Table 23. Midplane-to-Backplane Card Edge Connector #2 Pin-out for details. The use of card edge connectors to the back plane eliminates all hard drive cabling.

5.4.2.3 IOP80333 IO processor

The Intel 80333 IO processor is a multi-function device that integrates the Intel Xscale

core with intelligent peripherals and two PCIe* to PCI-X* bridges. It will be connected to the server board ’s x4 PCIe lane and serve as bridge for PCI-X 133MHz secondary bus. The IOP80333 also includes fully functional RAID support.

5.4.2.4 LSI* LSISAS1068 SAS Controller

The LSI* LSISAS1068 controller resides on the Channel A PCI-X bus of the IOP80333 supporting transfer rates of up to 3GB/s. It includes an Address Translation Unit (ATU) supporting transactions between PCI address space and 80333 address space. Address translation for the ATU is controlled through programmable registers accessible from both the

PCI interface and the Intel Xscale

core. The LSISAS1068 controller includes its own Flash

ROM and NVSRAM to support SAS only software RAID. Software RAID Levels supported include 0, 1, and 10.

5.4.2.5

The active mid-plane supports options to provide full hardware RAID support. Options required to enable hardware RAID support include an Intel

RAID Activation Key (product order code -

AXXRAK18E) and installation of a Mini-DIMM for Intel RAID Cache support. To protect from data loss during an unexpected power loss event, an Intel

RAID Smart Battery Backup module

(AXXRSBBU3) is also supported. Hardware RAID levels supported include 0, 1, 5, 10, and 50.

5.4.2.5.1 Intel® RAID Activation Key

The Intel

RAID Activation Key enables the full intelligent SAS Hardware RAID solution engineered around the Intel

80333 I/O Processor @ 500MHz. The activation key plugs directly in to a connector (J1A10) on the mid-plane board. With no RAID activation key installed, only

SAS Software RAID levels 0, 1, and 10 are supported.

5.4.2.5.2 Intel RAID Cache support

To further enable support for hardware RAID, the active mid-plane provides a 244-pin mini-

DIMM connector (J8C1), supporting a single registered ECC non-parity DDR2-400 MHz Mini-

DIMM to provide Intel RAID cache. Mini-DIMM capacities supported range from 128MB to 1GB.

Note: See the Intel

Server Board S5000PAL Tested Memory List for a list of Intel validated mini-DIMMs.

5.4.2.5.3 Intel

RAID Smart Battery Backup Module

With an Intel

RAID Smart Battery Backup module installed, data loss is prevented when data is still present in the RAID Cache Module and power is unexpectedly lost. Depending on the cache module capacity used, the battery backup unit can provide 48 to 72 hours of battery backup power to allow data stored in the RAID cache to be processed. A 2x10 connector (J9A2) is used to attach the battery backup unit to the mid-plane. See Table 24. Active Mid-plane SAS RAID

Battery Backup Connector Pin-out for details.

5.5.2.1 Enclosure Management Controller

The backplane utilizes the features of the Vitesse* VSC410 to implement several enclosure management functions. The chip provides in-band SAF-TE and SES management and utilizes the four I

C interfaces listed below.

1. I2C bus 0 is connected to an EEPROM which stores configuration and FRU data

2. I2C bus 1 is connected to an LM75 temperature sensor

3. I2C bus 2 is connected to an IPMB bus from the server board.

4. I2C bus 3 is connected to the LSISAS1068 SAS controller.

5.5.2.2 Hard Drive Activity and Fault LEDs

The backplanes support an activity/fault LED for each of the hard drive connectors. The LED will illuminate green for activity or amber for a drive fault. The green activity LED is driven by the

SAS/SATA hard disk drive directly. The amber fault LED is driven by the VSC410* management controller whenever a fault condition is detected. When the drive is used in a

RAID configuration, the RAID controller will have control over the fault LED and it may exhibit different behavior.

3. Also off when the system is powered off (S4/S5) or in a sleep state (S1).

4. The power LED sleep indication is maintained on standby by the chipset. If the system is powered down without going through BIOS, the LED state in effect at the time of power off will be restored when the system is powered on until the BIOS clears it. If the system is not powered down normally, it is possible that the

Power LED will be blinking at the same time that the system status LED is off due to a failure or configuration change that prevents the BIOS from running.

The current limiting resistors for the power LED, the system fault LED, and the NIC LEDs are located on the server board.

6.2.2.1 System Status LED – BMC Initialization

When AC power is first applied to the system and 5V-STBY is present, the BMC controller on the server board requires 15-20 seconds to initialize. During this time, the system status LED will blink, alternating between amber and green, and the power button functionality of the control panel is disabled, preventing the server from powering up. Once BMC initialization has completed, the status LED will stop blinking and the power button functionality is restored and can be used to turn on the Server.

6.2.3 Drive Activity LED

The drive activity LED on the front panel indicates drive activity from the onboard hard disk controllers. The Intel

Server Board S5000PAL also provides a header giving access to this

LED for add-in controllers.

6.2.4 System Identification LED

The blue system identification LED is used to help identify a system for servicing. This is especially useful when the system is installed when in a high density rack or cabinet that is populated with several similar systems.

The blue system ID LED can be illuminated using either of two mechanisms.

- By pressing the system ID button on the system control panel, the ID LED will display a solid blue color until the button is pressed again.

- By issuing the appropriate hex IPMI chassis identify value, the ID LED will either blink blue for 15 seconds and turn off or will blink indefinitely until the appropriate hex IPMI chassis identify value is issued to turn it off.

Local Control Panel Interconnects

The Intel

Local Control Panel module includes the control panel interface board and an interposer board. Connectors on the control panel interface board are cabled to matching connectors on the interposer board. When the pre-assembled control panel module is installed into the chassis, a card edge connector on the interposer card is blind mated with a slot edge connector on the backplane. This section will define the pin-out for each connector and header found on both the control panel interface board and interposer board.

• A 64-pin card edge connector on the interposer board is used to route signals to/from the backplane to the control panel interface board. The backplane is used as a conduit for communication to the server board.

•

Signals from the card edge connector are routed to control panel interface board through matching 50-pin connectors on the interposer board and control panel interface board.

The 50-pin connectors are attached using a small 50-pin flat cable.

• USB signals from the card edge connector are routed to the control panel interface board through matching 10-pin connectors on the interposer board and control panel interface board. The 10-pin connectors are attached using a small 10-pin round cable.

• A 4-pin IPMI header (not used).

• A 4-pin NMI/Temp Sensor header.

The following tables provide the pin-outs for each connector.

Intel® Server System SR2500AL

The chassis supports different riser card options depending on the add-in card configuration desired. The riser assembly for the chassis is tool-less. Stand-offs on the bracket allow the riser cards to slide onto the assembly where a latching mechanism than holds each riser in place.

Holding down the latch releases the risers for easy removal.

When re-inserting the riser assembly into the chassis, tabs on the back of the assembly should be aligned with slots on the back edge of the chassis. The tabs fit into the slots securing the riser assembly to the chassis when the top cover is in place.

The riser assembly provides two extraction levers to assist with riser assembly removal from the riser slots.

8.1 Riser Card Options

The Intel

Server Board S5000PAL has two riser slots capable of supporting riser cards for both

1U and 2U system configurations. Because of board placement resulting in different pin orientations, and expanded technology support associated with the full-height riser, the riser slots are not the same and require different riser cards.

The low profile riser slot (J5B1) utilizes a 98-pin connector. It is capable of supporting up to two low profile PCIe* add-in cards. The x8 PCIe bus can support bus speeds of up to 20Gb/S. The following table provides the supported bus throughput for the given riser card used and the number of add-in cards installed.

Low Profile Riser 1 add-in card 2 add-in cards

2U X4 X4

Note: There are no population rules for installing a single low profile add-in card in the 2U low profile riser card; a single add in card can be installed in either PCI Express* slot. While each slot can accommodate a x8 card, each slot will only support x4 bus speeds.

The full height riser slot (J4F1) implements Intel

Adaptive Slot Technology. This 280-pin connector is capable of supporting riser cards that meet either the PCI-X* or PCI Express* technology specifications. The following tables show the maximum bus speed supported with different add-in card populations.

2U – 3 add-in card slots Up to 100MHz in top PCI slot

2 add-in cards

Up to 100MHz using top and middle slots

3 add-in cards

66MHz

Note: For the 2U PCI-X* (passive) riser card, add-in cards should be installed starting with the top slot first, followed by the middle, and then the bottom. Any add-in card populated in the bottom PCI slot will cause the bus to operate at 66MHz.

Note: Each PCI slot on the 2U PCI-X* (active) riser card operates on an independent PCI bus.

Using an add-in card that operates below 133MHz will not affect the bus speed of the other PCI slots.

Platform control optimizes system performance and acoustics levels through:

Performance Management

Performance Throttling

Thermal Monitoring

Fan Speed Control

Acoustics Management

The system components used to implement platform control include:

Baseboard Management Controller functions of the ESB-2

Platform Sensors

Variable Speed System Fans

System BIOS

BMC Firmware

Sensor Data Records as loaded by the FRUSDR Utility

FBDIMM type

Intel order number D31980-004

Revision – 1.00

11.2 FBDIMM Open Loop Throughput Throttling

Memory throttling is a feature of the Intel

5000 Series Chipsets to prevent FBDIMM memory from overheating. If the performance of the installed FB-DIMMs approaches their supported thermal limit for a given platform, the system BIOS will initiate memory throttling which manages memory performance by limiting bandwidth to the DIMMs, therefore capping the power consumption and preventing the DIMMs from overheating. Memory throttling can be minimized by operating your platform in “Performance Mode” (default) which changes the system Fan

Control profile to run the system fans at higher speeds. Running the platform in “Acoustics

Mode” will cause the system fans to run slower to meet the acoustic limits for the given platform.

System BIOS utilizes a Memory Reference Code (MRC) throttling algorithm to maximize memory bandwidth for a given configuration when memory throttling is initialized. The MRC code relies on Serial Presence Detect (SPD) data read from the installed DIMMs as well as system level data as set through BIOS Setup Options and the FRUSDR Utility.

11.3 Fan Speed Control

System fan speed is controlled by the Baseboard Management Controller (BMC) functions of the ESB-2 chip. During normal system operation, the BMC will retrieve information from BIOS and monitor several platform thermal sensors to determine the required fan speeds.

In order to provide the proper fan speed control for a given system configuration, the BMC must have the appropriate platform data programmed. Platform configuration data is programmed using the FRUSDR Utility during the system integration process and by System BIOS during run time.

Revision – 1.00

Intel order number D31980-004

Platform Control Intel® Server System SR2500AL

The Field Replaceable Unit & Sensor Data Record Update Utility (FRUSDR utility) is a program used to write platform specific configuration data to NVRAM on the server board. It allows the

User to select which supported chassis (Intel or Non-Intel) and platform chassis configuration is being used. Based on the input provided, the FRUSDR writes sensor data specific to the configuration to NVRAM for the BMC controller to read each time the system is powered on.

11.3.2 Fan Speed Control from BMC and BIOS Inputs

Using the data programmed to NVRAM by the FRUSDR utility, the BMC is configured to monitor and control the appropriate platform sensors and system fans each time the system is powered on. After power-on, the BMC uses additional data provided to it by System BIOS to determine how the system fans should be controlled.

The BIOS provides data to the BMC telling it which fan profile the platform is setup for,

Acoustics Mode or Performance Mode. The BIOS uses the parameters retrieved from the thermal sensor data records (SDR), the fan profile setting from BIOS Setup, and the altitude setting from BIOS Setup to configure the system for memory throttling and fan speed control. If the BIOS fails to get the Thermal SDRs, then it will use the Memory Reference Code (MRC) default settings for the memory throttling settings.

The <F2> BIOS Setup Utility provides options to set the fan profile or operating mode the platform will operate under. Each operating mode has a predefined profile for which specific platform targets are configured, which in turn determines how the system fans operate to meet those targets. Platform profile targets are determined by which type of platform is selected when running the FRUSDR utility and by BIOS settings configured using the <F2> BIOS Setup Utility.

11.3.2.1 Configuring the Fan Profile Using the BIOS Setup Utility

The BIOS uses options set in the <F2> BIOS Setup Utility to determine what fan profile the system should operate under. These options include “SET FAN PROFILE” and “ALTITUDE”.

The “SET FAN PROFILE” option can be set to either the “Performance” mode (Default), or

“Acoustics” mode. See the following sections for detail describing the difference between each mode. Changing the fan profile to Acoustics mode may affect system performance.

The “ALTITUDE” option is used to determine appropriate memory performance settings based on the different cooling capability at different altitudes. At high altitude, memory performance must be reduced to compensate for thinner air. Be advised, selecting an Altitude option to a setting that does not meet the operating altitude of the server may limit the system fans ability to provide adequate cooling to the memory. If the air flow is not sufficient to meet the needs of the server even after throttling has occurred, the system may shut down due to excessive platform thermals.

By default, the Altitude option is set to 301Meters – 900 Meters which is believed to cover the majority of the operating altitudes for these server platforms.

The following Diagrams show which BIOS Setup Utility menu is used to configure the desired

Fan Profile.

300 M or less (<= 980ft): Provides the best performance option for servers operating at or near sea level.

301 M – 900 M (980ft - 2950ft): Provides the best performance option for servers operating at moderate altitudes above sea level.

Higher than 900 M (>2950ft): Provides the best performance option for servers operating at high elevations above sea level.

Comments

Performance mode favors using fans over throttling memory bandwidth to cool the system.

Note: Fan speed control for non-Intel chassis, as configured after running the FRUSDR utility and selecting the Non-Intel Chassis option, is limited to only the CPU fans. The BMC only requires the processor thermal sensor data ito determine how fast to operate these fans. The remaining system fans will operate at 100% operating limits due to unknown variables associated with the given chassis and its fans. Therefore, regardless of whether the system is configured for Performance Mode or Acoustics Mode, the System fans will always run at 100% operating levels providing for maximum airflow. In this scenario the Performance and Acoustic mode settings only affects the allowable performance of the memory (higher BW for the

Performance mode).

11.3.2.2 Performance Mode (Default)

With the platform running in Performance mode (default), several platform control algorithm variables are set to enhance the platform’s capability of operating at maximum performance targets for the given system. In doing so, the platform is programmed with higher fan speeds at lower external temperatures. This will result in a louder acoustic level than is targeted for the given platform, but the increased airflow of this operating mode will greatly reduce possible memory throttling from occurring and will reduce dynamic fan speed changes based on processor utilization.

With the platform running in Acoustics mode, several platform control algorithm variables are set to ensure acoustic targets are not exceeded for specified Intel platforms. In this mode, the

Appendix A: Chassis Integration and Usage Tips

This appendix provides a list of useful information that is unique to the Intel

Server Chassis

SR2500 and should be kept in mind while integrating and configuring your system. o In a single power supply configuration, the power supply must be placed in the lower slot. A power supply blank must be installed in the upper slot in order to maintain proper airflow in the system. o Do not mix DIMMs of different heights. For tall DIMMS the DIMM baffle must be removed from the Processor Air Duct for proper fitment. The baffle must be installed for shorter

DIMMS to ensure proper airflow and DIMM cooling. o You must run the FRUSDR utility to load the proper Sensor Data Records for this chassis on to the server board. Failure to do so may result in possible false errors being reported to the

System Event Log. It is best to download the latest FRUSDR Utility for your particular server board using the Intel

Server Deployment Toolkit or from the following web site: http://support.intel.com/support/motherboards/server o To ensure proper cooling of your server, all air baffles and air ducts must be in place. In addition, all drive bays must be populated with either a drive or a drive blank and both power supply slots must be populated by either a power supply or a power supply blank. o Processor fans are not supported and are not needed in the Intel

Server Chassis SR2500. o The Mid-plane board must be removed from the system before removal of the Backplane. o In order to remove or replace the Mid-plane board, the fan cage must first be removed. o There are three indentations in the top of the chassis. These are for the Intel Safety Label, the Windows Certification Label, and a Customer Defined Label.

Intel® Server System SR2500AL Appendix B: POST Code Diagnostic LED Decoder

Appendix B: POST Code Diagnostic LED Decoder

During the system boot process, BIOS executes a number of platform configuration processes, each of which is assigned a specific hex POST code number. As each configuration routine is started, BIOS will display the given POST code to the POST Code Diagnostic LEDs found on the back edge of the server board. To assist in troubleshooting a system hang during the POST process, the Diagnostic LEDs can be used to identify the last POST process to be executed.

Each POST code will be represented by a combination of colors from the four LEDs. The LEDs are capable of displaying three colors: green, red, and amber. The POST codes are divided into two nibbles, an upper nibble and a lower nibble. Each bit in the upper nibble is represented by a red LED and each bit in the lower nibble is represented by a green LED. If both bits are set in the upper and lower nibbles then both red and green LEDs are lit, resulting in an amber color. If both bits are clear, then the LED is off.

In the below example, BIOS sends a value of ACh to the diagnostic LED decoder. The LEDs are decoded as follows:

• red bits = 1010b = Ah

• green bits = 1100b = Ch

Since the red bits correspond to the upper nibble and the green bits correspond to the lower nibble, the two are concatenated to be ACh.

POST Progress Code Description

System halted because a fatal error related to the memory was detected.

The system has detected a corrupted BIOS in the flash part, and is rolling back to the last good BIOS.

The BMC may generate beep codes upon detection of failure conditions. Beep codes are sounded each time the problem is discovered, such as on each power-up attempt, but are not sounded continuously. Codes that are common across all Intel

server boards and systems that use the Intel

5000 Series Chipsets are listed in Table 59. Each digit in the code is represented by a sequence of beeps whose count is equal to the digit.
