1.3 Special Features
Recovery from AC Power Loss
The Basic I/O System (BIOS) provides a setting that determines 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 o (in which case you must press the power switch to turn it back on), or
for it to automatically return to the power-on state. See the Advanced BIOS Setup section
for this setting. The default setting is Last State.

19
Chapter 1: Introduction
1.4 System Health Monitoring
Onboard Voltage Monitors
An onboard voltage monitor will scan the voltages of the onboard chipset, memory, CPU,
and battery continuously. Once a voltage becomes unstable, a warning is given, or an error
message is sent to the screen. The user can adjust the voltage thresholds to dene the
sensitivity of the voltage monitor.
Fan Status Monitor with Firmware Control
The system health monitor embedded in the BMC chip can check the RPM status of the
cooling fans. The CPU and chassis fans are controlled via lPMI.
Environmental Temperature Control
System Health sensors monitor temperatures and voltage settings of onboard processors
and the system in real time via the IPMI interface. Whenever the temperature of the CPU or
the system exceeds a user-dened threshold, system/CPU cooling fans will be turned on to
prevent the CPU or the system from overheating.
Note: To avoid possible system overheating, be sure to provide adequate airow to
your system.
System Resource Alert
This feature is available when used with SuperDoctor 5 ® in the Windows OS or in the Linux
environment. SuperDoctor is used to notify the user of certain system events. For example,
you can congure SuperDoctor to provide you with warnings when the system temperature,
CPU temperatures, voltages and fan speeds go beyond a predened range.
1.5 ACPI Features
The Advanced Conguration and Power Interface (ACPI) specication denes a exible and
abstract hardware interface that provides a standard way to integrate power management
features throughout a computer system, including its hardware, operating system and
application software. This enables the system to automatically turn on and o peripherals
such as CD-ROMs, network cards, hard disk drives and printers.
In addition to enabling operating system-directed power management, ACPI also provides a
generic system event mechanism for Plug and Play, and an operating system-independent
interface for conguration control. ACPI leverages the Plug and Play BIOS data structures,
while providing a processor architecture-independent implementation that is compatible with
appropriate Windows operating systems. For detailed information regarding OS support, refer
to the Supermicro website.

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 where
noisy power transmission is present.
The X12SDV-4C/8C/14C/16C/20C-SPT8F motherboard accommodates a 24-pin ATX power
supply. Although most power supplies generally meet the specications required by the CPU,
some are inadequate. In addition, one 12 V 8-pin power connection is also required to ensure
adequate power supply to the system.
Warning: To avoid damaging the power supply or the motherboard, be sure to use a
power supply that contains a 24-pin and an 8-pin power connector. Be sure to con-
nect the power supplies to the 24-pin power connector (JPWR1), and the 8-pin power
connector (JPV1) on the motherboard. Failure in doing so may void the manufacturer
warranty on your power supply and motherboard.
Note: The X12SDV-4C/8C/14C/16C/20C-SPT8F motherboard alternatively supports
an 8-pin 12 V DC input power supply for embedded applications. The 12 V DC input
is limited to a 36 A design. It provides up to 432 W power input to the motherboard.
Keep onboard power use within the power limits specied above. Over current DC
power use may cause damage to the motherboard.
It is strongly recommended that you use a high quality power supply that meets ATX power
supply Specication 2.02 or above.
1.7 Serial Port
The X12SDV-4C/8C/14C/16C/20C-SPT8F motherboard supports one serial communication
connection. COM1 can be used for input/output. The UART provides legacy speeds with a
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 high-speed serial communication devices.

2.1 Static-Sensitive Devices
Electrostatic Discharge (ESD) can damage electronic com ponents. To avoid damaging your
system board, it is important to handle it very carefully. The following measures are generally
sucient 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 motherboard 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 that your computer chassis provides excellent conduc-
tivity between the power supply, the case, the mounting fasteners and the motherboard.
• Use only the correct type of onboard CMOS battery. 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 motherboard, make sure that the person handling it is static protected.

2.2 Motherboard Installation
All motherboards have standard mounting holes to t dierent types of chassis. Make sure
that the locations of all the mounting holes for both the motherboard and the chassis match.
Although a chassis may have both plastic and metal mounting fasteners, metal ones are highly
recommended because they ground the motherboard to the chassis. Make sure that the metal
standos click in or are screwed in tightly.
Location of Mounting Holes
Note 1: To avoid damaging the motherboard and its components, do not use a
force greater than 8 lbf-in on each mounting screw during motherboard installation.
Note 2: Some components are very close to the mounting holes. Take precautionary
measures to avoid damaging these components when installing the motherboard to
the chassis.
