Power Supply - Supermicro X7DBT-INF User Manual

Main Switch Override Mechanism
When a power supply is used, the power button can function as a system suspend
button to make the system enter a SoftOff state. The monitor will be suspended
and the hard drive will spin down. Pressing the power button again will cause the
whole system to wake up. During the SoftOff state, the 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 Boot Features Section under Advanced
Setup in the BIOS.
External Modem Ring-On
Wake-up events can be triggered by a device such as the external modem ringing
when the system is in the SoftOff state. Note that external modem ring-on can only
be used with an ATX 2.01 (or above) compliant power supply.
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, updates and asset-
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. In addition, an onboard LAN controller can also support WOL
without any connection to the WOL header. The 3-pin WOL header is to be used
with a LAN add-on card only.
