Chipset Voltage (+1.5V),+1.8V, +3.3V, +5V, +12V, −12V, +3.3V
Standby, +5V standby, HT 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.
Users can adjust the voltage thresholds to defi ne 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 2 (TM2) 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-defi ned
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.

CPU Fan Auto-Off in Sleep Mode
The CPU fan activates when the power is turned on. It continues to operate when
the system enters Standby mode. When in sleep mode, the CPU will not run at
full power, thereby generating less heat.
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 defi ne an overheat temperature. When the
temperature exceeds a user pre-defi ned threshold, both overheat fan and 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 insuffi cient hard drive space for saving the
data, you can be alerted of the potential problem. You can also confi gure Supero
Doctor to provide you with warnings when the system temperature goes beyond
a pre-defi ned range.
1-5 ACPI Features
ACPI stands for Advanced Confi guration and Power Interface. The ACPI specifi -
cation defi nes a fl exible 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 confi guration control. ACPI leverages the Plug
and Play BIOS data structures while providing a processor architecture-independent
implementation that is compatible with both Windows 2000 and Windows NT 5.0.
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.
1-12
Chapter 1: Introduction
Main Switch Override Mechanism
When a 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 power supply provides
power to keep the required circuitry in the system alive. In case the system mal-
functions 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 Boot Features Section under Advanced
Setup in the BIOS.
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 defi ned as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, updates and asset-
tracking can occur after hours and on weekends so that daily LAN traffi c 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.
1-6 Power Supply
Supermicro's proprietary power connectors are used in the X7DBT/X7DBT-INF/
X7DGT/X7DGT-INF. Please refer to Section 2-5 Connecting Cables on Page 2-14
for more information.

2-1 Static-Sensitive Devices
Electric-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 suffi cient 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 specifi ed by the manu-
facturer. Do not install the onboard battery upside down to avoid possible explo-
sion.
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.

When handling the processor package, avoid placing
direct pressure on the label area of the fan.
(*Notes: 1. Always connect the power cord last and always remove it before adding,
removing or changing any hardware components. Make sure that you install the
processor into the CPU socket before you install the CPU heatsink.
2. Intel's boxed Xeon CPU package contains the CPU fan and heatsink assembly.
If you buy a CPU separately, make sure that you use only Intel-certifi ed multi-di-
rectional heatsink and fan.
3. Make sure to install the motherboard into the chassis before you install the CPU
heatsink and fan.)
4. When purchasing an LGA 771 CPU or when receiving a motherboard with an 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.

Mounting the Motherboard in the Chassis
All motherboards have standard mounting holes to fi t different types of chas-
sis. 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 to the chassis.)

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)
1. 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, then DIMM #2A and so on. For optimal
performance, please install four modules of the same type and same speed
in Branch 0 and Branch 1 at a time (up to 8 modules maximum). (*See the
Memory Installation Table Below.)
2. 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.
3. 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 X7DBT/X7DBT-INF/X7DGT/X7DGT-INF supports up to 32 GB fully buffered
(FBD) ECC DDR2 533/667 in 8 DIMMs. Populating DIMM modules with pairs
of memory modules of the same size and same type will result in Interleaved
Memory which will increase memory performance.
*Note 1: Due to OS limitations, some operating systems may not show more than
4 GB of memory.

(*Notes: i. DIMM slot# specified: DIMM slot to be populated; “---“: DIMM
slot not to be populated. ii. Both FBD 533 MHz and 667MHz DIMMs are
supported; however, you need to use the memory modules of the same
speed and of the same type on a motherboard. iii. Interleaved memory is
supported when pairs of DIMM modules are installed. To optimize memory
performance, please populate pairs of memory modules in both Branch 0
and Branch 1. iv. For memory to work properly, you need to follow the
restrictions listed above. )
