The 5100 chipset supports single or dual Intel Xeon 64-bit Quad-Core/Dual-Core 5400/5300/5200/5100 Series processors with front side bus speeds of up to 1.333 GHz. The chipset consists of the 5100 Memory Controller Hub (MCH), Intel I/O Controller Hub (ICH9R) and the I/O subsystem. The 5100 Memory Controller Hub (MCH) The Intel 5100 MCH chip is designed for symmetric multiprocessing across two independent front side bus interfaces. Each front side bus uses a 64-bit wide, 1066/1333 MTS data bus capable of transferring data at 8.5/10.6 GB/s for a total bandwidth of 17/21.3 GB/s. The MCH supports a 36-bit wide address bus and up to six DDR2 667 MHz/533 MHz DIMM modules, providing a total memory capacity of up to 48 GB. The 5100 MCH also provides six x4 PCI-Express interfaces and one x4 DMI Interface to the ICH9R. Each PCI Express port on the MCH provides 4 GB/s bi- directional bandwidth if configured as a x8 port, or 2 GB/s bi-directional bandwidth if configured as a x4 port. The Ninth Generation I/O Controller Hub (ICH9) The I/O Controller ICH9R provides the data buffering and interface arbitration re- quired for the system to operate efficiently. It also provides the bandwidth needed for the system to maintain its peak performance. The Direct Media Interface (DMI) provides the connection between the MCH and the ICH9R. The ICH9R supports up to six PCI-Express x1 slots, six Serial ATA ports and eight USB 2.0 ports. In addition, the ICH9R offers the Intel Matrix Storage Technology which provides vari- ous RAID options for data protection and rapid data access. It also supports the next generation of client management through the use of PROActive technology in conjunction with Intel's next generation Gigabit Ethernet controllers. The Xeon Quad-Core/Dual-Core 5400/5300/5200/5100 Series Processor Features In addition, the Intel Xeon Quad-Core/Dual-Core 5400/5300/5200/5100 Series Processor-based platforms offer a wide range of RAS (Reliability, Availability, and Serviceability) features, including memory interface ECC, x4 Single Device Data Correction, parity protection, and out-of-band register access via SMbus. 1-9 X7DCA-L User's Manual 1-3 Special Features Recovery from AC Power Loss BIOS provides a setting for you to determine how the system will respond when AC power is lost and then restored to the system. You can choose for the system to remain powered off (in which case you must hit the power switch to turn it back on) or for it to automatically return to a power- on state. See the Power Lost Con- trol setting in the Advanced BIOS Setup section to change this setting. The default setting is Last State. 1-4 PC Health Monitoring This section describes the PC health monitoring features of the X7DCA-L. All have an onboard System Hardware Monitor chip that supports PC health monitoring. Onboard Voltage Monitoring An onboard voltage monitor will scan the following voltages continuously: CPU core voltage, Memory voltage, Chipset, +3.3V, +5V, +12V, -12V, +3.3V standby, +5V standby and VBAT. Once a voltage becomes unstable, a warning is given or an error message is sent to the screen. Users can adjust the voltage thresholds to define the sensitivity of the voltage monitor. Fan Status Monitor with Firmware Control The PC health monitor can check the RPM status of the cooling fans. The onboard CPU and chassis fans are controlled by Thermal Management via BIOS (under Hardware Monitoring in the Advanced Setting). Environmental Temperature Control The thermal control sensor monitors the CPU temperature in real time and will turn on the thermal control fan whenever the CPU temperature exceeds a user-defined threshold. The overheat circuitry runs independently from the CPU. Once it detects that the CPU temperature is too high, it will automatically turn on the thermal fan control to prevent any overheat damage to the CPU. The onboard chassis thermal circuitry can monitor the overall system temperature and alert users when the chas- sis temperature is too high. 1-10 Chapter 1: Introduction CPU Overheat LED and Control This feature is available when the user enables the CPU overheat warning function in the BIOS. This allows the user to define an overheat temperature. When the CPU temperature reaches the pre-defined overheat threshold, both the overheat fan and the warning LED are triggered. System Resource Alert This feature is available when used with Supero Doctor III in the Windows OS environment or used with Supero Doctor II in Linux. Supero Doctor is used to notify the user of certain system events. For example, if the system is running low on virtual memory and there is insufficient hard drive space for saving the data, you can be alerted of the potential problem. You can also configure Supero Doctor to provide you with warnings when the system temperature goes beyond a pre- defined range. 1-5 ACPI Features ACPI stands for Advanced Configuration and Power Interface. The ACPI specifica- tion defines a flexible and abstract hardware interface that provides a standard way to integrate power management features throughout a PC system, including its hardware, operating system and application software. This enables the system to automatically turn on and off peripherals such as CD-ROMs, network cards, hard disk drives and printers. This also includes consumer devices connected to the PC such as VCRs, TVs, telephones and stereos. In addition to enabling operating system-directed power management, ACPI provides a generic system event mechanism for Plug and Play and an operating system-independent interface for configuration control. ACPI leverages the Plug and Play BIOS data structures while providing a processor architecture-independent implementation that is compatible with Windows 2000, Windows XP and Windows 2003 Servers. Slow Blinking LED for Suspend-State Indicator When the CPU goes into a suspend state, the chassis power LED will start blinking to indicate that the CPU is in suspend mode. When the user presses any key, the CPU will wake-up and the LED will automatically stop blinking and remain on. 1-11 X7DCA-L User's Manual Main Switch Override Mechanism When an ATX power supply is used, the power button can function as a system suspend button to make the system enter a SoftOff state. The monitor will be suspended and the hard drive will spin down. Pressing the power button again will cause the whole system to wake-up. During the SoftOff state, the ATX power supply provides power to keep the required circuitry in the system alive. In case the system malfunctions and you want to turn off the power, just press and hold the power button for 4 seconds. This option can be set in the Power section of the BIOS Setup routine. External Modem Ring-On Wake-up events can be triggered by a device such as the external modem ringing when the system is in the Standby or Off state. The external modem ring-on can only be used with an ATX 2.01 (or above) compliant power supply. Wake-On-LAN is defined as the ability of a management application to remotely power up a computer that is powered off. Remote PC setup, up-dates and asset tracking can occur after hours and on weekends so that daily LAN traffic is kept to a minimum and users are not interrupted. The motherboard has a 3-pin header (WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has WOL capability. In addition, an onboard LAN controller can also support WOL without any connection to the WOL header. The 3-pin WOL header is to be used with a LAN add-on card only. Note: Wake-On-LAN requires an ATX 2.01 (or above) compliant power supply. 1-6 Power Supply As with all computer products, a stable power source is necessary for proper and reliable operation. It is even more important for processors that have high CPU clock rates. The X7DCA-L can only accommodate 24-pin ATX power supply. Although most power supplies generally meet the specifications required by the motherboard, some are inadequate. You should use one that will supply at least 400W of power. In addition, the 12V 8-pin is also required for adequate power supply to the CPU. Also your power supply must supply 1.5A for the Ethernet ports. It is strongly recommended that you use a high quality power supply that meets ATX power supply Specification 2.02 or above. It must also be SSI compliant (info at ssiforum.org/). Additionally, in areas where noisy power transmission is present, you may choose to install a line filter to shield the computer from noise. It is recommended that you also install a power surge protector to help avoid prob- lems caused by power surges. 1-12 Chapter 1: Introduction 1-7 Super I/O The disk drive adapter functions of the Super I/O chip include a floppy disk drive controller that is compatible with industry standard 82077/765, a data separator, write pre-compensation circuitry, decode logic, data rate selection, a clock generator, drive interface control logic and interrupt and DMA logic. The wide range of functions integrated onto the Super I/O greatly reduces the number of components required for interfacing with floppy disk drives. The Super I/O supports 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s. It also provides two high-speed, 16550 compatible serial communication ports (UARTs). Both UARTs provide legacy speed with baud rate of up to 115.2 Kbps as well as an advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support higher speed modems. The Super I/O provides functions that comply with ACPI (Advanced Configuration and Power Interface), which includes support of legacy and ACPI power manage- ment through an SMI or SCI function pin. It also features auto power management to reduce power consumption. 1-13 X7DCA-L User's Manual Notes 1-14 Chapter 2: Installation Chapter 2 Installation 2-1 Static-Sensitive Devices Electro-Static-Discharge (ESD) can damage electronic com ponents. To prevent damage to your system board, it is important to handle it very carefully. The following measures are generally sufficient to protect your equipment from ESD. Precautions • Use a grounded wrist strap designed to prevent static discharge. • Touch a grounded metal object before removing the board from the antistatic bag. • Handle the board by its edges only; do not touch its components, peripheral chips, memory modules or gold contacts. • When handling chips or modules, avoid touching their pins. • Put the motherboard and peripherals back into their antistatic bags when not in use. • For grounding purposes, make sure your computer chassis provides excellent conductivity between the power supply, the case, the mounting fasteners and the motherboard. • Use only the correct type of onboard CMOS battery as specified by the manufacturer. Do not install the onboard battery upside down to avoid possible explosion. Unpacking The motherboard is shipped in antistatic packaging to avoid static damage. When unpacking the board, make sure the person handling it is static protected. 2-1 2-2 Processor and Heatsink Installation Warning: When handling the processor package, avoid placing direct pressure on the label area of the fan. Notes: Always connect the power cord last and always remove it before adding, 1. removing or changing any components. Make sure that you install the pro- cessor into the CPU socket before you install the CPU heatsink. Intel's boxed Xeon CPU package contains the CPU fan and heatsink assem- 2. bly. If you buy a CPU separately, make sure that you use only Intel-certified multi-directional heatsink and fan. Make sure to install the motherboard into the chassis before you install the 3.

The motherboard must be shipped with the PnP cap properly installed to protect the CPU socket pins. Shipment without the PnP cap properly installed will cause damage to the socket pins. X7DCA-L User's Manual Installing the Heatsink CEK Heatsink Installation CEK Passive Heatsink 1. Do not apply any thermal grease to the heatsink or the CPU die; the required amount has already been applied. 2. Place the heatsink on top of the CPU so that the four mounting holes are Screw#1 Screw#2 aligned with those on the retention mechanism. 3. Screw in two diagonal screws (ie the #1 and the #2 screws) until just snug (-do not fully tighten the screws to avoid possible damage to the CPU.) 4. Finish the installation by fully tightening all four screws. Screw#2 To Un-install the Heatsink Warning: We do not recommend that the CPU or the heatsink be removed. However, if you do need to uninstall the heatsink, please ! follow the instructions on the next page to uninstall the heatsink to prevent damage done to the CPU or the CPU socket. 2-4 Screw#1

Chapter 2: Installation 1. Unscrew and remove the heatsink screws from the motherboard in the sequence as shown in the picture on the right. 2. Hold the heatsink as shown in the pic- ture on the right and gently wriggle the heatsink to loosen it from the CPU. (Do not use excessive force when wriggling the heatsink!!) 3. Once the heatsink is loosened, remove the heatsink from the CPU socket. 4. Clean the surface of the CPU and the heatsink to get rid of the old thermal grease. Reapply the proper amount of thermal grease on the surface be- fore you re-install the CPU and the heatsink. Mounting the Motherboard in the Chassis

All motherboards have standard mounting holes to fit different types of chassis. Make sure that the locations of all the mounting holes for both motherboard and chassis match. Make sure that the metal standoffs click in or are screwed in tightly. Then, use a screwdriver to secure the motherboard onto the motherboard tray. Note: some components are very close to the mounting holes. Please take precautionary measures to prevent damage done to these components when you install the motherboard into the chassis. Caution: To avoid damaging the motherboard and its components, please do not use a force greater than 8 lb/inch on each mounting screw during motherboard installation. 2-5 X7DCA-L User's Manual 2-3 Installing DIMMs Note: Check the Supermicro web site for recommended memory modules. CAUTION Exercise extreme care when installing or removing DIMM modules to prevent any possible damage. Also note that the memory is interleaved to improve performance (see step 1). DIMM Installation (See Figure 2-2) Insert the desired number of DIMMs into the memory slots, starting with DIMM • #1A. The memory scheme is interleaved, so you must install two modules at a time, beginning with DIMM 1A, DIMM 1B, then DIMM 2A, DIMM 2B, and DIMM 3A, DIMM 3B. Insert each DIMM module vertically into its slot. Pay attention to the notch along • the bottom of the module to prevent inserting the DIMM module incorrectly. Gently press down on the DIMM module until it snaps into place in the slot. • Repeat for all modules (see step 1 above). Memory Support The X7DCA-L supports up to 48 GB Buffered (Registered) ECC DDR2 667/533 in 6 DIMMs. Populating memory slots of the same bank with a pair of memory modules of the same size and same type will result in two-way Interleaved Memory which will improve memory performance. Notes: 1: Due to OS limitations, some operating systems may not show more than 4 GB of memory. 2: Due to memory allocation to system devices, memory remaining avail- able for operational use will be reduced when 4 GB of RAM is used. The reduction in memory availability is disproportional. (Refer to the following Memory Availability Table for details. For Microsoft Windows users: Microsoft implemented a design change in Windows XP with Service Pack 2 (SP2) and Windows Vista. This change is specific to the Physical Address Extension (PAE) mode behavior which improves driver compatibility.

The Phoenix ROM BIOS is stored in a flash chip and can be easily upgraded using a floppy disk-based program. Note: Due to periodic changes to the BIOS, some settings may have been added or deleted and might not yet be recorded in this manual. Please refer to the Manual Download area of the Supermicro web site < supermicro.com> for any changes to the BIOS that may not be reflected in this manual. System BIOS The BIOS is the Basic Input Output System used in all IBM® PC, XTTM, AT®, and PS/2® compatible computers. The Phoenix BIOS stores the system parameters, types of disk drives, video displays, etc. in the CMOS. The CMOS memory requires very little electrical power. When the computer is turned off, a backup battery pro- vides power to the CMOS Logic, enabling it to retain system parameters. When the computer is powered on, the computer is configured with the values stored in the CMOS Logic by the system BIOS, which gains control at boot up. How To Change the Configuration Data The CMOS information that determines the system parameters may be changed by entering the BIOS Setup utility. This Setup utility can be accessed by pressing the <Delete> key at the appropriate time during system boot. From the main menu, you can access the other setup screens, such as the Security and Power menus. Beginning with Section 4-3, detailed descriptions are given for each parameter setting in the Setup utility.

Refer to the the next item, CPU Temperature for more information regarding PECI, DTS and other thermal features of this motherboard. Warning: Any temperature that exceeds the CPU threshold temperature predefined by the CPU manufacturer may result in CPU overheat or system instability. When the CPU temperature reaches this predefined threshold, the CPU and system cooling fans will run at full speed. The options are: The Default Alarm Setting: Select this setting if you want the CPU overheat alarm (including the LED and the buzzer) to be triggered when the CPU temperature reaches about +5 PECI counts above the threshold temperature as predefined by the CPU manufacturer to give the CPU and system fans additional time needed for CPU and system cooling. The Early Alarm Setting: Select this setting if you want the CPU overheat alarm (including the LED and the buzzer) to be triggered as soon as the CPU temperature reaches the CPU overheat threshold as predefined by the CPU manufacturer. CPU1 Temperature/CPU2 Temperature The CPU Temperature feature will display the CPU temperature status as detected by the BIOS: Low – This level is considered as the ‘normal’ operating state. The CPU temperature is well below the CPU ‘Temperature Tolerance’. The motherboard fans and CPU will run normally as configured in the BIOS (Fan Speed Control). User intervention: No action required. Medium – The processor is running warmer. This is a ‘precautionary’ level and gen- erally means that there may be factors contributing to this condition, but the CPU is still within its normal operating state and below the CPU ‘Temperature Tolerance’. The motherboard fans and CPU will run normally as configured in the BIOS. The fans may adjust to a faster speed depending on the Fan Speed Control settings. User intervention: No action is required. However, consider checking the CPU fans and the chassis ventilation for blockage. High – The processor is running hot. This is a ‘caution’ level since the CPU’s ‘Tem- perature Tolerance’ has been reached (or has been exceeded) and may activate an overheat alarm: 4-18 The Default Alarm – the Overheat LED and system buzzer will activate if the High condition continues for some time after it is reached. The CPU fan will run at full speed to bring the CPU temperature down. If the CPU temperature still increases even with the CPU fan running at full speed, the system buzzer will activate and the Overheat LED will turn on. The Early Alarm – the Overheat LED and system buzzer will be activated exactly when the High level is reached. The CPU fan will run at full speed to bring the CPU temperature down. Note: In both the alarms above, please take immediate action as shown below. See CPU Overheat Alarm to modify the above alarm settings. User intervention: If the system buzzer and Overheat LED has activated, take action immediately by checking the system fans, chassis ventilation and room temperature to correct any problems. Note: the system may shut down if it con- tinues for a long period to prevent damage to the CPU. Notes: The CPU thermal technology that reports absolute temperatures (Celsius/Fahrenheit) has been upgraded to a more advanced feature by Intel in its newer processors. The basic concept is each CPU is embedded by unique temperature information that the motherboard can read. This ‘Temperature Threshold’ or ‘Temperature Tolerance’ has been assigned at the factory and is the baseline on which the motherboard takes action during different CPU temperature conditions (i.e., by increasing CPU Fan speed, triggering the Overheat Alarm, etc). Since CPUs can have different ‘Temperature Tolerances’, the installed CPU can now send information to the motherboard what its ‘Temperature Tolerance’ is, and not the other way around. This results in better CPU thermal management. Supermicro has leveraged this feature by assigning a temperature status to certain thermal conditions in the processor (Low, Medium and High). This makes it easier for the user to understand the CPU’s temperature status, rather than by just simply seeing a temperature reading (i.e., 25oC). The information provided above is for your reference only. For more infor- mation on thermal management, please refer to Intel’s Web site at Intel.com. System Temperature1 This feature displays the system's absolute temperature reading (i.e., 29oC). Fan1-Fan6: If the feature of Auto Fan Control is enabled, the BIOS will automatically display the status of the fans indicated in this item. Chapter 4: BIOS 4-19 X7DCA-L User's Manual Fan Speed Control Modes This feature allows the user to decide how the system controls the speeds of the onboard fans. The CPU temperature and the fan speed are correlative. When the CPU on-die temperature increases, the fan speed will also increase, and vice versa. Select Workstation if your system is used as a Workstation. Select Server if your system is used as a Server. Select “Disable” to disable the fan speed control function and allow the onboard fans to constantly run at the full speed (12V). The Options are: 1. Disabled (Full Speed @12V), 2. 4-pin (Quiet), 3. 4-pin (Super Quiet), 4. Optimized Server w/4-pin, and 5. Optimized Workstation w/4-pin. Voltage Monitoring The following items will be monitored and displayed: VcoreA/VcoreB, 12V, 1.8V, 5V, 3.3V, 3.3Vsb, Vbat Note: In the Windows OS environment, the Supero Doctor III settings take precedence over the BIOS settings. When first installed, Supero Doctor III adopts the temperature threshold settings previously set in the BIOS. Any subsequent changes to these thresholds must be made within Supero Doc- tor, since the SD III settings override the BIOS settings. For the Windows OS to adopt the BIOS temperature threshold settings, please change the SDIII settings to be the same as those set in the BIOS. 4-20 4-5 Security Choose Security from the Phoenix BIOS Setup Utility main menu with the arrow keys.

Check to see if fixed disk is attached properly. Run Setup. Find out if the fixed-disk type is correctly identified. Stuck key Stuck key on keyboard. Keyboard error Keyboard not working. Keyboard Controller Failed Keyboard controller failed test. May require replacing keyboard controller. Keyboard locked - Unlock key switch Unlock the system to proceed. Monitor type does not match CMOS - Run SETUP Monitor type not correctly identified in Setup Shadow Ram Failed at offset: nnnn Shadow RAM failed at offset nnnn of the 64k block at which the error was de- tected. System RAM Failed at offset: nnnn System RAM failed at offset nnnn of in the 64k block at which the error was de- tected. A-1 X7DCA-L User's Manual Extended RAM Failed at offset: nnnn Extended memory not working or not configured properly at offset nnnn. System battery is dead - Replace and run SETUP The CMOS clock battery indicator shows the battery is dead. Replace the battery and run Setup to reconfigure the system. System CMOS checksum bad - Default configuration used System CMOS has been corrupted or modified incorrectly, perhaps by an applica- tion program that changes data stored in CMOS. The BIOS installed Default Setup Values. If you do not want these values, enter Setup and enter your own values. If the error persists, check the system battery or contact your dealer. System timer error The timer test failed. Requires repair of system board. Real time clock error Real-Time Clock fails BIOS hardware test. May require board repair. Check date and time settings BIOS found date or time out of range and reset the Real-Time Clock. May require setting legal date (1991-2099). Previous boot incomplete - Default configuration used Previous POST did not complete successfully. POST loads default values and offers to run Setup. If the failure was caused by incorrect values and they are not corrected, the next boot will likely fail. On systems with control of wait states, improper Setup settings can also terminate POST and cause this error on the next boot. Run Setup and verify that the waitstate configuration is correct. This error is cleared the next time the system is booted. Memory Size found by POST differed from CMOS Memory size found by POST differed from CMOS. A-2
