Overview and Specifications
Power Supply
1.6.1 Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start blinking
to indicate that the CPU is in suspend mode. When the user presses any key, the
CPU will wake-up and the LED will automatically stop blinking and remain on.
1.6.2 Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a system sus-
pend button to make the system enter a SoftOff state. The monitor will be suspended
and the storage drive will spin down. Pressing the power button again will cause the
whole system to wake-up. During the SoftOff state, the ATX power supply provides
power to keep the required circuitry in the system “alive.” In case the system mal-
functions and you want to turn off the power, just press and hold the power button
for 4 seconds. This option can be set in the Power section of the BIOS Setup routine.
1.7 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 RES-32XR3/FIO motherboard can accommodate 24-pin ATX power supplies.
Although most power supplies generally meet the specifications required by the
CPU, some are inadequate. In addition, the 12V 8-pin power connections are also
required to ensure adequate power supply to the system. Also your power supply
must supply 1.5A for the Ethernet ports.
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 web site at http://www.ssiforum.org/). Additionally,
in areas where noisy power transmission is present, you may choose to install a line
Caution: To prevent damage to your power supply or motherboard, please use a
power supply that contains a 24-pin and two 8-pin power connectors. Be sure to
connect these power connectors to the 24-pin and the two 8-pin power connectors
on your motherboard for adequate power supply to your system. Failure to do so
will void the manufacturer warranty on your power supply and motherboard.
