Intel® Server System SR1550AL Product Overview

Revision – 1.3

Intel order number D31982-006

1. Product Overview

The Intel® Server Chassis SR1550 is a 1U server chassis that is designed to support the Intel® Server Board S5000PAL and Intel

Server Board S5000XAL. Together, the integrated products

make up the Intel

Server System SR1550AL. The server boards and chassis have feature sets designed to support the high-density server market. This chapter provides a high-level overview of the system features. Greater detail for each major system component or feature is provided in the following chapters.

The Intel

Server System SR1550AL represents a major departure from previous generation products. Most cables have been removed from the system and replaced by a series of boardto-board interconnects. Using board-to-board interconnects simplifies platform integration and improves airflow for more reliable cooling.

A second significant change from the previous generation of products is the introduction of the mid-plane system board. There are two options for this board: The first option is a cable-less “active” mid-plane which includes an onboard SAS controller providing SAS / SAS RAID support. The second option is a “passive” mid-plane which provides cabled point-to-point interconnects to support either the onboard SATA ports of the server board, or to a SATA or SAS PCI add-in card.

1.4 System Boards/Components

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

• Brid ge 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 Point-to-Point – cabled to SATA ports on the server board or from add-in

SATA or SAS adapter card.

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

• Riser Cards – PCI riser cards used to provide up to two add-in card slots to the system. Available riser card options for this system include:

• RAID Activation Keys – The system provides different RAID options depending on the mid-plane option selected. Two RAID Activation Keys are available for this system

o Hardware RAID Activation Key – Used on the Active SAS/SAS RAID Mid-plane

to enable hardware RAID support.

o Software SATA RAID 5 Activation Key – This RAID key plugs into a connector on

the server board. It is used to enable the software SATA RAID 5 functionality of the ESB2 SATA ports of the server board when cabled to the passive mid-plane.

1.5 Control Panel Options

The Intel® Server System SR1550AL can support three types of control panels: mini control panel, standard control panel, and an Intel

Local Control Panel with LCD support. Each control panel is pre-assembled and modular in design. The entire control panel slides into a predefined slot in the front of the chassis.

1.8 System Cooling

The cooling subsystem for this system consists of air baffles, a CPU air duct, and a tool-less fan module which houses five 56 mm dual rotor system fans. In addition, each power supply module includes a 56 mm dual rotor fan module which pulls air from inside the chassis and blows it out the back. Coupled with the onboard server management functionality of the server board, the cooling sub-system provides sufficient airflow to maintain internal system thermal requirements when the external ambient temperature remains within specified limits.

Note: The cooling sub-system for this system provides no fan redundancy. Should any of the system fans fail, the system should be shut down as soon as possible to have the failed fan replaced.

1.9 System Security

The system 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 system was designed to support 19” wide by up to 30” deep server cabinets. The chassis supports three rack mount options: A fixed mount relay rack / cabinet mount, a tool-less sliding rail kit, or a basic three-quarter extension sliding rail kit. The fixed mount relay rack / cabinet mount kit can be configured to support both 2-post racks and 4-post cabinets. The tool-less sliding rail kit or basic rail kit is used to mount the chassis into a standard (19” by up to 3 0” deep ) EIA-310D compatible server cabinet. An optional Cable Management Arm can be used with the tool-less sliding rail kit only.

1.11 Front Bezel Features

The optional front bezel options are made of molded plastic and use a snap-on design with a key lock. When installed, the design allows for maximum airflow.

2.1.1 DC Output Connection (card edge)

2.2 Single Power Supply Module Population

In single power module configurations, server management firmware requires that power supply module #1 be populated. The power module #1 slot is located closest to the baseboard away from the side edge of the chassis. See the diagram below. The non-operating slot must have the power supply blank installed.

Configuring a single power supply module in the #2 module slot will cause the server management firmware and BIOS to generate a system error during POST and to the System Event Log and will cause the System Status LED on the control panel to blink green, denoting a degraded system configuration.

2.3 Handle and Retention Mechanism

Each power supply module includes a handle allowing 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

so that it prevents inserting the module with the power cord plugged in. This will aid the hotswapping procedure.

2.4 Hot-swap Support

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 following method:

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

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

2.5 Output Cable Harness

The power distribution board connects to the system via a wire harness. The harness size, connectors, and pin outs are shown below. Listed or recognized component appliance wiring material (AVLV2), CN, Rated 105°C Min, 300Vdc Min shall be used for all output wiring.

The PS+PDB will be protected against over-temperature conditions caused by loss of fan cooling, excessive ambient temperature, or excessive loading. Two sensing points shall be placed at hot spots; one near the exterior face and one near the interior face of the module. In an OTP condition the PSU will shutdown. When the power supply temperature drops to within specified limits, the power supply shall restore power automatically, while the 5 VSB remains always on. The OTP circuit must have built in hysteresis such that the power supply will not oscillate on and off due to temperature recovering condition. The OTP trip level shall have a minimum of 4°C of ambient temperature hysteresis.

3. Cooling Subsystem

Several components and configuration requirements make up the cooling sub-system. These include the system fan module, the power supply fans, power supply air duct, 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 60. System Environmental Limits.

The system has a non-redundant system cooling configuration consisting of five 40x40x56mm dual rotor system fans to provide sufficient airflow to maintain internal system thermal requirements when the external ambient temperature remains within specified limits. Should a single fan failure occur, the system should be shut down and the failed fan replaced as soon as possible.

In addition to the system fans, each power supply module installed provides an additional 56mm dual rotor fan which pulls air from inside the chassis and blows it out the back.

The system utilizes an integrated platform control mechanism to manage a variable fan speed control engine to provide adequate cooling for the system. (See Chapter 4 – Platform Control for more information.) In the event of a fan failure, the BMC will boost the remaining fans as a means to compensate for the lost air flow. If the cooling is not sufficient under a failed fan condition the system will eventually shutdown as a means to protect itself from thermal damage.

3.1 Fan Module

The system fan module houses five 40x40x56mm dual rotor system fans. The module has been designed for ease of use and has support for several management features that can be utilized by the baseboard management system. The system fan module and individual fans do not require tools for installation or removal.

Figure 16. Fan Module

Page 34

Intel® Server System SR1550AL Cooling Subsystem

Revision – 1.3

Intel order number D31982-006

The individual system fans are not hot-swappable and require the system to be turned off before being replaced. The chassis is classified as a “Service Access Only” device and caution should be exercised when replacing a system fan, as they do not have finger guards. However, provisions are built into the fan bracket to prevent service technicians from accidental contact with fan rotors. 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 two tachometer signals (one for each fan rotor) allowing for baseboard management to monitor the status of each fan rotor. 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 system fan has an associated fan fault LED which is located next to its respective fan cable connector on the mid-plane board. The fan fault LED is controlled by the BMC. If either fan rotor within a system fan fails, it will illuminate the fan fault LED and log the failure into the System Event Log.

3.2 Air Flow Support

To control airflow within the system, a power supply air duct and CPU air duct are used to isolate and direct airflow to three critical areas or zones: the power supply zone, the full height PCI zone, and the CPU/memory/low profile PCI zone.

3.2.1 Power Supply Zone

A molded plastic air duct / baffle is used to isolate the air flow of the main system board zones from the zone directly in front of the power supply modules. The power supply fans pull preheated air from the leftmost drive bays across the Power Distribution Board to cool its voltage regulators.

Figure 18. Power Supply Air Duct

3.2.2 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 FAN #5 of the fan module. Air is drawn from the drive bay area through the fan and pushed out of the system through ventilation holes at back of the chassis.

Page 36

Intel® Server System SR1550AL Cooling Subsystem

Revision – 1.3

Intel order number D31982-006

3.2.3 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. The air flow for this zone is generated by system fans FAN #1 - #4 of the fan module. 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.

A CPU air duct is used to direct air flow through the processor heat sinks for both single and dual processor configurations. For dual processor configurations, an air baffle attached to the underside of the air duct is removed.

Note: The air baffle should ONLY be removed when a 2

processor is installed. Operating a single processor configuration with the air baffle removed may result in the processor over heating and may cause the system to shutdown.

Figure 19. CPU Air Duct

Note: Once the air baffle is removed from the air duct, it cannot be re-attached.

5. System Board Interconnects

The system incorporates several design changes from the previous generation Intel 1U server chassis, resulting in improved cable routing or eliminating several cable interconnects altogether. System boards within the chassis include two types of mid-planes, a bridge board, a hard drive backplane, three types of PCI riser boards, and three types of control panels. 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.

5.1 Mid-Plane

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

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

Figure 21. Passive Mid-Plane Board

The system also supports an active SAS / SAS RAID mid-plane. This system board incorporates an LSI* LSISAS1068 SAS controller onto the board. See Chapter 6 for details describing SAS / SAS RAID support. The following diagram shows the location for each connector found on this board.

The system can be configured to support up to eight hot-swap 2.5” 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.

6.2.1 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 purpos e latc hing mechanism which is used to insert and extract drives from the chassis, and lock the tray assembly in place. Each drive tray supports two light pipes viewable from the front of the chassis. The light pipes provide a green drive activity indicator and amber drive fault indicator. The drive activity and fault LEDs are located on the backplane next to each drive connector.

6.3 Mid-Plane Options

New to this generation of high density server system 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 cabled passive mid-plane capable of supporting SATA ports from the server board or SAS/SATA 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.

6.3.1 Passive Mid-Plane

The passive mid-plane option is used when the system configuration requires the use of an add-in SATA or SAS controller or the on-board SATA ports from the server board are used. The drive control signals are cabled to the passive mid-plane.

The mid-plane plugs directly into the hot swap backplane using two edge connectors, routing the hard drive signals to the appropriate hard drive connectors on the backplane. 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.

Figure 28. Passive Mid-Plane Board

6.3.2 Active Mid-plane with Intel® 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 eight SAS drives in this system. 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.

6.3.2.2 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.

6.3.2.3 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.

6.3.2.4 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.

6.3.2.5 Optional Hardware RAID Support

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.

6.3.2.5.1 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.

6.3.2.5.2 Intel RAID Cache support

To further enable support for hardware RAID, the active mid-plane provides a 244-pin miniDIMM connector (J8C1), supporting a single registered ECC non-parity DDR2-400 MHz MiniDIMM 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.

6.3.2.5.3 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.

6.4.2.2 Hard Drive Activity and Fault LED’s

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.

Table 38. Hard Drive LED Function Definitions

STATUS LED DEFINITION

GREEN ON HDD Activity AMBER ON HDD Fault

The activity LED functionality is controlled directly by the hard drives. This causes the LED to function differently between SAS and SATA drives. The expected operation is outlined below.

2. The amber status takes precedence over the green status. When the amber LED is on or blinking, the green LED is off.

3. 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.

7.2.2.1 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 30-35 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.

7.2.3 System Identification LED

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.

7.3 External Mini Control Panel Connectors

The mini control panel has one external USB port.

9.1.2.1 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 30-35 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.

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.

9.2 Intel® Local Control Panel Interconnects

The Intel® Local Control Panel module includes the Intel® Local Control Panel interface board and a USB interface board. Connectors on the Intel

Local Control Panel interface board and USB interface board are cabled to matching connectors on the hot-swap backplane. This section will define the pin-out for each connector and header found on both the Intel

Local

Control Panel interface board and interposer board.

• Signals from the card edge connector are routed to the Intel

Local Control Panel interface board through matching 50-pin connectors on the interposer board and the Intel

Local 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 Intel

Local Control Panel interface board through matching 10-pin connectors on the interposer board and the Intel

Local Control Panel interface board. The 10-pin connectors are attached using a

small 10-pin round cable.

• A 4-pin NMI/Temp Sensor Header (cables between the Intel

Local Control Panel

interface board and the USB interface board).

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

10. PCI Riser Cards and Assembly

The Intel® Server Boards S5000PAL and S5000XAL provide two PCI riser slots, one supporting a low profile add-in card riser, and the other used for full height add-in card risers. The riser cards for these slots are not interchangeable due to their orientation on the board and connector differences. The low profile riser slot is only capable of supporting a riser using PCI Express* cards. The full height riser slot is capable of supporting risers that follow either the PCI-X* or PCI Express specifications.

The riser assembly for the server chassis is tool-less. Stand-offs 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 blue extraction levers to assist with riser assembly removal from the riser slots.

Appendix A: Integration and Usage Tips Intel® Server System SR1550AL

Revision – 1.3

Intel order number D31982-006

Appendix A: Integration and Usage Tips

This appendix provides a list of useful information that is unique to the SR1550 server chassis and should be kept in mind while integrating and configuring your system.

o You must run the FRUSDR utility to load the proper Sensor Data Records for this system 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 from the following web site: http://support.intel.com/support/motherboards/server

o To ensure proper cooling of your server, all air ducts must be in place. In addition, all drive

bays must be populated with either a drive or a drive blank.

o Processor fans are not supported and are not needed in this server chassis. o Make sure all system boards, peripherals, and cables are detached from the backplane

before removing the backplane from the system. Failure to detach components from the backplane before removal may result in component damage.

o The cooling sub-system for this system provides no fan redundancy. Should any of the

system fans fail, the system should be shut down as soon as possible to have the failed fan replaced.

In order to prevent data loss due to power interruptions of any duration, it is recommended

that a Uninterruptible Power Source (UPS) be used anytime unstable line power may exist.

o The air baffle should ONLY be removed when a 2

processor is installed. Operating a single processor configuration with the air baffle removed may result in the processor over heating and may cause the system to shutdown. Once the air baffle is removed from the air duct, it cannot be re-attached.

o When AC power is first applied to the system and 5V-STBY is present, the BMC controller

on the server board requires 30-35 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.

o Only Dual-Core Intel

Xeon® processors 5000 sequence, that support system bus speeds of

667 MHz, 1066 MHz, and1333 MHz are supported on this server system.

Intel® Server System SR1550AL Appendix B: POST Code Diagnostic LED Decoder

Revision – 1.3

Intel order number D31982-006

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.
