the system to keep the required circuitry "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.
Power supply
A stable power source is necessary for proper and reliable operation. It is even more
important for processors that have high CPU clock rates of 1 GHz and faster.
The X8SIL/X8SIL-F/X8SIL-V accommodates ATX12V standard power supplies. Although most
power supplies generally meet the specifications required by the CPU, some are inadequate. A
2-Amp of current supply on a 5V Standby rail is strongly recommended.
It is strongly recommended that you use a high quality power supply that meets ATX12V
standard power supply Specification 1.1 or later. It is also required that the 12V 8-pin power
connection (JPW2) be used for adequate power supply. In areas where noisy power
transmission is present, you may choose to install a line filter to shield the computer from
noise. It is recommended that you also install a power surge protector to help avoid problems
caused by power surges.
DIVAR IP 7000 does not have a function to determine pre-failure of a power supply. The power
supply will have the LED to show it is “OK” or “failed” by showing the color green or amber for
the respective status. When the power supply fails, it shows amber, when it is functioning
correctly it shows green.
Super I/O
The disk drive adapter functions of the Super I/O chip include a floppy disk drive controller
that is compatible with industry standard 82077/765, a data separator, write pre-
compensation circuitry, decode logic, data rate selection, a clock generator, drive interface
control logic and interrupt and DMA logic. The wide range of functions integrated onto the
Super I/O greatly reduces the number of components required for interfacing with floppy disk
drives. The Super I/O supports two 360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data
transfer rates of 250 Kb/s, 500 Kb/s or 1 Mb/s.
It also provides two high-speed, 16550-compatible serial communication ports (UARTs). Each
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 support 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 management through a SMI or
SCI function pin. It also features auto power management to reduce power consumption.
iSCSI support
The X8SIL/X8SIL-F/X8SIL-V motherboard supports the iSCSI Internet Protocol. iSCSI is an IP
networking standard used to link and manage data storage, and transfer data across the
internet and private intranets through long distance. iSCSI can be used to transmit data over
local area networks (LANs), wide area networks (WANs), or the Internet. It can enable
location-independent data storage and retrieval.
iSCSI allow clients to issue SCSI commands to remote SCSI storage devices and allow data
centers to consolidate remote storage devices into storage arrays, giving an illusion of locally-
attached disks to host servers. Unlike fiber-optic networks that require special cabling, iSCSI
can run over long distance using existing networks.
