X8SIT-F User’s Manual
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blink-
ing to indicate that the CPU is in the suspend mode. When the user presses any
key, the CPU will wake-up and the LED indicator will automatically stop blinking
and remain on.
BIOS Support for USB Keyboard
If the USB keyboard is the only keyboard in the system, it will function like a normal
keyboard during system boot-up.
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system
suspend button. When the user presses the power button, the system will enter
a SoftOff state. The monitor will be suspended and the hard drive will spin down.
Press the power button again to wake-up the whole system. During the SoftOff
state, the ATX power supply provides power the system to keep the required cir-
cuitry "alive". In case the system malfunctions and you want to turn off the power,
just press and hold the power button for 4 seconds. The power will turn off and no
power will be provided to the motherboard.
1-5 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 X8SIT-F can only accommodate Supermicro proprietary power supply. Please
refer to Section 3-6 for more information.
1-6 Super I/O
The X8SIT-F provides one high-speed, 16550-compatible serial communication
ports (UARTs). This UART includes a 16-byte send/receive FIFO, a programmable
baud rate generator, complete modem control capability and a processor interrupt
system. 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 sup-
port higher speed modems.
The Super I/O provides functions that comply with ACPI (Advanced Configuration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through a SMI or SCI function pin. It also features auto power management
to reduce power consumption.
