Block Diagram of the 5400 Chipset
Note: This is a general block diagram. Please see the previous Motherboard Features pages for details on the features of the motherboard.
1-2 Chipset Overview
Built upon the functionality and the capability of the 5400 chipset, the X7DWA-N motherboard provides the performance and feature set required for quad-core-processor- or dual-core-processor-based high-end workstations with configuration options optimized for complex system platforms. The 5400 chipset supports single or dual Intel Quad-Core/Dual-Core Xeon 5400/5300/5200/5100 Series processors with front side bus speeds of up to 1.6 GHz. The chipset consists of the 5400 Memory Controller Hub (MCH) for the host bridge and the 631xESB/632xESB I/O Controller Hub (Enterprise South Bridge 2-ESB2) for the I/O subsystem.
The Intel 5400 MCH (North Bridge)
The 5400 MCH (North Bridge) provides two FSB processing interfaces, four fully buffered (FBD) DIMM memory channels, PCI-Express x4 bus interfaces configurable to form x8 or x16 ports, an EB2 South Bridge Interface (ESI) and SMBus Interfaces for system management, and DIMM Serial Presence Detect (SPD). The PCI-Express x4 interfaces can be configured to form x8 or x16 ports that can operate up to Gen-2 speeds in x16 configuration for enhanced graphics applications.
The Intel 631xESB/632x ESB I/O Controller Hub-ESB2 (South Bridge)
The 631xESB/632xESB I/O Controller Hub (Enterprise South Bridge 2) integrates an Ultra ATA 100 Controller, six Serial ATA host controller ports, one EHCI host controller, six USB 2.0 ports, an LPC interface controller, and a flash BIOS interface controller. Additionally, the ESB 2 chip also contains a PCI interface controller, Azalia/'97 digital controller, integrated LAN controller, an ASF controller, and an ESI for communication with the MCH. The Intel ESB2 offers the data buffering and interface arbitration capabilities required for a high-end system to constantly operate efficiently and maintain peak performance.
Compliant with the ACPI platform, the ESB2 supports the Full-On, Stop-Grant, Suspend-to-RAM, Suspend-to-Disk, and Soft-Off power management states. Combined with the functionality offered by the onboard LAN controller, the ESB2 also supports alert systems for remote management.
With the 5400 chipset built in, the X7DWA-N offers a superb solution for intense computing and complex I/O environments, and is ideal for high-end server systems.
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 Control setting in the Advanced BIOS Setup section to change the setting. The default setting is Last State.
1-4 PC Health Monitoring
This section describes the PC health monitoring features of the X7DWA-N. All have an onboard System Hardware Monitor chip that supports PC health monitoring.
Onboard Voltage Monitors for the CPU Cores, Chipset Voltage, Memory Voltage, +1.8V, +3.3V, +5V, +12V, -12V, +3.3V Standby, +5V Standby and Vbat
An onboard voltage monitor will scan these voltages continuously. Once a voltage becomes unstable, a warning is given or an error message is sent to the screen.
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 increase fan speed whenever the CPU temperature reaches a user-defined threshold. The onboard chassis thermal circuitry can monitor the overall system temperature and alert users when the chassis temperature is too high.
CPU Fan Auto-Off in Sleep Mode
When the power is turned on, the CPU fan becomes active. It stops to operate when the system enters Standby mode. When in sleep mode, the CPU will not run at full power, thereby generating less heat.
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 specification defines a flexible and abstract hardware interface that provides a standard 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, Windows 2003, Windows 2003 Servers and Windows Vista.
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 CPU is in the S1 mode, the Power LED blinks every second. When in the S3 mode, the Power LED will blink every 5-second. When the user presses any key, the CPU will wake-up and the LED will automatically stop blinking and remain on.
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 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 power button for 4 seconds. This option can be set in the Advanced Setup 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 SoftOff state. Note that external modem ring-on can only be used with an ATX 2.01 (or above) compliant power supply.
Wake-On-LAN (WOL)
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 X7DWA-N can only accommodate 24-pin ATX power supplies. Although most power supplies generally meet the specifications required by the CPU, some are inadequate. You should use one that will supply at least 500W of power. In addition, the 12V 4-pin power and the 12V 8-pin are also required for adequate power supply to the system. 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 2.01 or above. It must also be SSI compliant (Refer to the web site at http://www.ssiforum.org/ for more information). 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 problems caused by power surges.
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). Each UART includes a 16-byte send/receive FIFO. 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 supports one PC-compatible printer port (SPP), Bi-directional Printer Port (BPP), Enhanced Parallel Port (EPP) or Extended Capabilities Port (ECP).
The Super I/O provides functions that comply with ACPI (Advanced Configuration and Power Interface), which includes support of legacy and ACPI power management through an SMI or SCI function pin. It also features auto power management to reduce power consumption.

Installation
2-1 Static-Sensitive Devices
Electrostatic Discharge (ESD) can damage electronic components. To prevent damage to your system board, it is important to handle it very carefully. The following procedures 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.
2-2 Motherboard Installation
Note: Be sure to mount the motherboard into the chassis before you install the CPU onto the motherboard.
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 to these components when installing the motherboard to the chassis.
2-3 Processor and Heatsink Installation

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 hardware components. Make sure that you install the processor 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.
When purchasing an LGA 771 CPU or when receiving a motherboard with an 3. LGA 771 CPU pre-installed, make sure that the CPU plastic cap is in place and none of the CPU pins are bent; otherwise, contact the retailer immediately.
Refer to the MB Features Section for more details on CPU support.4.

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 Bank 1. (Refer to the Memory Configuration Table below for more details.)
- 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 X7DWA-N supports up to 64 GB fully buffered (FBD) ECC DDR2 800/667/533 in 8 DIMMs. Populating DIMM modules with a pair (or pairs) of memory modules of the same type and same size will result in interleaved memory. For best performance, please install (a) pair(s) of DIMM modules of the same type in both Branch 0 and Branch 1.
| Memory Configuration Table | ||||||||
| Branch0 Branch1 | ||||||||
| Number of DIMMs | Bank 1 (Channel 0) | Bank 2 (Channel 1) | Bank 3 (Channel 2) | Bank 4 (Channel 3) | ||||

High Definition Audio (HD Audio)
The X7DWA-N features a 7.1+2 Channel High Definition Audio (HDA) (JC1) codecs that provides 10DAC channels, simultaneously supporting 7.1 sound playback with 2 channels of independent stereo sound output (multiple streaming) through the front panel stereo out (for front L&R, rear L&R), center and subwoofer speakers. Use the advanced software included in the CD-ROM with your motherboard to enable this function. Sound is then output through the Line-In, Line-Out and MIC jacks (see the graphics at right). Enable this feature in the BIOS to use this feature.

Front Panel Audio Control
When front panel headphones are plugged in, the back panel audio output is disabled. This is done through the FP Audio header (JC2). If the front panel interface card is not connected to the front panel audio header, jumpers should be installed on the header (JC2) pin pairs: 1-2, 5-6, and 9-10. If these jumpers are not installed, the back panel line out connector will be disabled and microphone input Pin 1 will be left floating, which can lead to excessive back panel microphone noise and cross talk. See the table below for pin definitions.

2-7 Jumper Settings
Explanation of Jumpers
To modify the operation of the motherboard, jumpers can be used to choose between optional settings. Jumpers create shorts between two pins to change the function of connector. Pin 1 is identified with a square solder pad on the printed circuit board. See the motherboard layout pages for jumper locations.
Note: On two pin jumpers, "Closed" means the jumper is on and "Open" means the jumper is off the pins.

CMOS Clear
JBT1 is used to clear CMOS. Instead of pins, this "jumper" consists of contact pads to prevent accidental clearing of CMOS. To clear CMOS, use a metal object such as a small screwdriver to touch both pads at the same time to short the connection. Always remove the AC power cord from the system before clearing CMOS.
Note: For an ATX power supply, you must completely shut down the system, remove
the AC power cord and then short JBT1 to clear CMOS.

Watch Dog Enable/Disable
Watch Dog is a system monitor that can reboot the system when a software application hangs. Close pins 1-2 to reset the system if an application hangs. Close pins 2-3 to generate a non-maskable interrupt signal for the application that hangs. See the table on the right for jumper settings. Watch Dog must also be enabled in the BIOS.

Notes
Chapter 3 Troubleshooting
3-1 Troubleshooting Procedures
Use the following procedures to troubleshoot your system. If you have followed all of the procedures below and still need assistance, refer to the 'Technical Support Procedures' and/or 'Returning Merchandise for Service' section(s) in this chapter.
Note: Always disconnect the power cord before adding, changing or installing any hardware components.
Before Power On
- Make sure that there are no short circuits between the motherboard and chassis.
- Disconnect all ribbon/wire cables from the motherboard, including those for the keyboard and mouse.
- Remove all add-on cards.
- Install one CPU (making sure it is fully seated) and connect the chassis speaker and the power LED to the motherboard. (Check all jumper settings as well.)
No Power
- Make sure that there are no short circuits between the motherboard and chassis..
- Make sure that all jumpers are set to their default positions.
- Check that the 115V/230V switch on the power supply is properly set.
- Turn the power switch on and off to test the system.
- The battery on your motherboard may be old. Check to make sure that it still supplies \~3VDC. If it does not, replace it with a new one.
No Video
- If the power is on but you have no video, remove all the add-on cards and cables.
- Use the speaker to determine if any beep codes exist. Refer to Appendix B for details on beep codes.
- Remove all memory modules and turn on the system. (If the alarm is on, check the specs of the memory, reset the memory or try a different one.)
Losing the System's Setup Configuration
- Make that you are using a high quality power supply. A poor quality power supply may cause the system to lose the CMOS setup information. Refer to Section 1-6 for details on recommended power supplies.
- The battery on your motherboard may be old. Check to verify that it still supplies \~3VDC. If it does not, replace it with a new one.
- If the above steps do not fix the Setup Configuration problem, contact your vendor for repairs.
Note
If you are a system integrator, VAR or OEM, a POST diagnostics card is recommended. For I/O port 80h codes, refer to App. B.
Memory Errors
- Make sure the DIMM modules are properly and fully installed.
- Check if different speeds of DIMMs have been installed, and make sure that the BIOS setup is configured for the fastest speed of RAM used. It is recommended to use the same RAM speed for all DIMMs in the system.
- Make sure you are using the correct type of DDR2 FBD (Fully Buffered) ECC 800/667/533 SDRAM (recommended by the manufacturer). Also make sure that the type of memory used is supported by the CPU installed on the motherboard. Refer to Page 2-6 for more information.
- Check for bad DIMM modules or slots by swapping a single module between four slots and noting the results.
- Make sure all memory modules are fully seated in their slots. As an interleaved memory scheme is used, you must install two modules at a time, beginning with 1A, then 1B, and so on (see Page 2-6).
- Check the position of the 115V/230V switch on the power supply.
3-2 Technical Support Procedures
Before contacting Technical Support, please take the following steps. Also, Note that as a motherboard manufacturer, Super Micro does not sell directly to end-users, so it is best to first check with your distributor or reseller for troubleshooting services. They should know of any possible problem(s) with the specific system configuration that was sold to you.
-
Please go through the 'Troubleshooting Procedures' and 'Frequently Asked Question' (FAQ) sections in this chapter or see the FAQs on our web site (http://www.supermicro.com/support/faqs/) before contacting Technical Support.
-
BIOS upgrades can be downloaded from our web site at (http://www.supermicro.com/support/bios/)
Note: Not all BIOS can be flashed; it depends on the modifications to the boot block code.
-
If you still cannot resolve the problem, include the following information when contacting Super Micro for technical support:
-
Motherboard model and PCB revision number
- BIOS release date/version (this can be seen on the initial display when your system fi rst boots up)
- System configuration
An example of a Technical Support form is on our web site at (http://www.supermicro.com/support/contact.cfm).
- Distributors: For immediate assistance, please have your account number ready when placing a call to our technical support department. We can be reached by e-mail at support@supermicro.com or by fax at: (408) 503-8000, option 2.
3-3 Frequently Asked Questions
Question: What are the various types of memory that my motherboard can support?
Answer: The X7DWA-N has eight 240-pin DIMM slots that support DDR2 FBD ECC 800/667/533 SDRAM modules. It is strongly recommended that you do not mix memory modules of different speeds and sizes.
Question: How do I update my BIOS?
Answer: It is recommended that you do not upgrade your BIOS if you are not experiencing any problems with your system. Updated BIOS files are located on our web site at http://www.supermicro.com/support/bios/. Please check our BIOS warning message and the information on how to update your BIOS on our web site. Select your motherboard model and download the BIOS file to your computer. Also, check the current BIOS revision and make sure that it is newer than your BIOS before downloading. You can choose from the zip file and the .exe file. If you choose the zip BIOS file, please unzip the BIOS file onto a bootable USB device. Run the batch file using the format flash.bat filename.rom from your bootable USB device to flash the BIOS. Then, your system will automatically reboot. If you choose the .exe file, please run the .exe file under Windows to create the BIOS flash floppy disk. Insert the floppy disk into the system you wish to flash the BIOS. Then, bootup the system to the floppy disk. The BIOS utility will automatically flash the BIOS without
any prompts. Please note that this process may take a few minutes to complete. Do not be concerned if the screen is paused for a few minutes.

Warning: Do not shut down or reset the system while updating BIOS to prevent possible system boot failure!
Question: What's on the CD that came with my motherboard?
Answer: The supplied compact disc has quite a few drivers and programs that will greatly enhance your system. We recommend that you review the CD and install the applications you need. Applications on the CD include chipset drivers for the Windows OS, security and audio drivers.
3-4 Returning Merchandise for Service
A receipt or copy of your invoice marked with the date of purchase is required before any warranty service will be rendered. You can obtain service by calling your vendor for a Returned Merchandise Authorization (RMA) number. When returning to the manufacturer, the RMA number should be prominently displayed on the outside of the shipping carton, and mailed prepaid or hand-carried. Shipping and handling charges will be applied for all orders that must be mailed when service is complete.
For faster service, you can also request a RMA authorization online (http://www.supermicro.com/support/rma/).
This warranty only covers normal consumer use and does not cover damage incurred in shipping or from failure due to the alternation, misuse, abuse or improper maintenance of products.
During the warranty period, contact your distributor first for any product problems.
Chapter 4
BIOS
4-1 Introduction
This chapter describes the Phoenix BIOS™ Setup utility for the X7DWA-N. The Phoenix ROM BIOS is stored in a flash chip and can be easily upgraded using a fi oppy 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 http://www.supermicro.com for any changes to the BIOS that may not be reflected in this manual.
System BIOS
BIOS is the Basic Input Output System used in all IBM ^ PC, XT ^TM , AT ^ , and PS/2 ^ compatible computers. The Phoenix BIOS utility stores the system parameters, types of disk drives, video displays, etc. in the CMOS. CMOS memory requires very little electrical power. When the computer is turned off, a backup batt provides 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
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
Starting the Setup Utility
Normally, the only visible POST (Power On Self Test) routine is the memory test. As the memory is being tested, press the

CPU Temperature/System Temperature

Note: The following item display current temperature readings for the CPU and the system. These items are displayed for your reference only.
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).
Medium – The processor is running warmer. This is a ‘precautionary’ level and generally 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.
High – The processor is running hot. This is a ‘caution’ level since the CPU’s ‘Temperature Tolerance’ has been reached (or has been exceeded) and may activate an overheat alarm. The system may shut down if it continues for a long period to prevent damage to the CPU.
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.
System Temperature
Fan1-Fan8 Speeds: If the feature of Auto Fan Control is enabled, the BIOS will automatically display the status of the fans indicated in this item.
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 3-pin if your chassis uses 3-pin fans. Select 4-pin if your chassis uses 4-pin fans. Select "Disable" to disable the fan speed control function and allow the onboard fans to constantly run at full speed (12V). The Options are: 1. Disable (Full Speed), 2. 3-pin (Server), and 3. 3-pin (Workstation).
Voltage Monitoring
The following items will be monitored and displayed:
VcoreA/VcoreB
+12V/-12V
+5Vsb/+5VDD
+3.3V
P1V5/CPU_VTT/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 Doctor, 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.

The Supero Doctor III program is a Web-based management tool that supports remote management capability. It includes Remote and Local Management tools. The local management is called the SD III Client. The Supero Doctor III program included on the CDROM that came with your motherboard allows you to monitor the environment and operations of your system. Supero Doctor III displays crucial system information such as CPU temperature, system voltages and fan status. See the Figure below for a display of the Supero Doctor III interface.
Note 1: The default user name and password are ADMIN.
Note 2: 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 Doctor, 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.
