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
appropriate Windows operating systems. For detailed information regarding OS support,
please 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.
Several busbars from power distribution boards provide power to the X13DGU motherboard.
The power distribution boards in the system are connected to Supermicro proprietary power
supplies.
It is strongly recommended that you only use Supermicro approved redundant power supply
units for the Supermicro system chassis.
1.7 System Reboot
This motherboard, intended to be used in a Supermicro GPU server, supports an innovative
cooling technology, which will continue cooling down the system even after shutting down.
After the system is shutdown, the power button LED on the front panel will start to blink green,
indicating that the cooling procedure is in progress. This cooling procedure will take 120
seconds to complete. When the procedure is complete, the power button LED will turn solid
amber. We recommend the user to allow this cooling procedure to complete before issuing
a power-on command or removing power cable(s) from the system.
1.8 Serial Port
The X13DGU motherboard supports one serial port via a header on the I/O board. COM Port
(JCOM1) is used for input/output. The UART provides legacy speeds with a baud rate of up
to 115.2 Kbps.
