Power Supply; Serial Port - Supermicro X11SRA User Manual

Super X11SRA/-F/-RF User's Manual
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 configuration control. ACPI leverages the Plug and Play BIOS data structures,
while providing a processor architecture-independent implementation that is compatible with
Windows 7, Windows 8, and Windows 2012 Operating Systems.

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 X11SRA/-F/-RF motherboard accommodates a 24-pin ATX power supply. Although most
power supplies generally meet the specifications required by the CPU, some are inadequate.
In addition, one 12V 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
power supplies that contain 24-pin and 8-pin power connectors. Be sure to connect
the power supplies to the 24-pin power connector (JPWR2) and the 8-pin power
connector (JPWR1) on the motherboard. Failure in doing so may void the manu-
facture warranty on your power supply and motherboard.
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. (For more information,
please refer to the website at http://www.ssiforum.org/). Additionally, in areas where noisy
power transmission is present, you may choose to install a line filter to shield the computer
from noises. It is recommended that you also install a power surge protector to help avoid
problems caused by power surges.

1.7 Serial Port

The X11SRA/-F/-RF motherboard supports one serial communication connection. COM1
header 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.
