H8DA6+/I+(-F) Serverboard User’s Manual
Main Switch Override Mechanism
The power button can function as a system suspend button. When the user de-
presses the power button, the system will enter a SoftOff state. The monitor will be
suspended and the hard drive will spin down. Depressing the power button again
will cause the whole system to wake-up. During the SoftOff state, the power sup-
ply provides power to keep the required circuitry in the system alive. In case the
system malfunctions and you want to turn off the power, just depress and hold the
power button for 4 seconds. The power will turn off and no power will be provided
to the motherboard.
Wake-On-LAN (WOL)
Wake-On-LAN is defi ned as the ability of a management application to remotely
power up a computer that is powered off. Remote PC setup, up-dates and access
tracking can occur after hours and on weekends so that daily LAN traffi c is kept
to a minimum and users are not interrupted. The motherboard has a 3-pin header
(WOL) to connect to the 3-pin header on a Network Interface Card (NIC) that has
WOL capability. Wake-On-LAN must be enabled in BIOS.
Wake-On-Ring Header (WOR)
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the SoftOff state.
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 H8DA6+/I+(-F) requires the use of proprietary power supplies. Please refer
to the pinout information for the power connectors in Section 6 of Chapter 2 for
detailed information on power requirements.
In areas where noisy power transmission is present, you may choose to install a
line fi lter 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.
Warning:
To prevent the possibility of explosion, do not use the wrong type of
onboard CMOS battery or install it upside down.
