1.13.2 Hardware Support

CAUTION
If Wake on LAN and Instantly Available technology features are used, ensure that the power
supply provides adequate +5 V standby current. Failure to do so can damage the power supply.
The total amount of standby current required depends on the wake devices supported and
manufacturing options. Refer to Section 2.11.3 on page 71 for additional information.
The board provides several hardware features that support power management, including:
Power connector
Fan connectors
Wake on LAN technology (optional)
Instantly Available technology
Resume on Ring
Wake from USB
Wake from PS/2 keyboard
PME# wakeup support
Wake on LAN technology and Instantly Available technology require power from the +5 V
standby line. The sections discussing these features describe the incremental standby power
requirements for each.
Resume on Ring enables telephony devices to access the computer when it is in a power-managed
state. The method used depends on the type of telephony device (external or internal) and the
power management mode being used (APM or ACPI).
NOTE
The use of Resume on Ring technology from an ACPI state requires the support of an operating
system that provides full ACPI functionality.
1.13.2.1 Power Connector
When used with an ATX-compliant power supply that supports remote power on/off, the board can
turn off the system power through software control. To enable soft-off control in software,
advanced power management must be enabled in the BIOS Setup program and in the operating
system. When the system BIOS receives the correct APM command from the operating system,
the BIOS turns off power to the computer.
With soft-off enabled, if power to the computer is interrupted by a power outage or a disconnected
power cord, when power resumes, the computer returns to the power state it was in before power
was interrupted (on or off). The computer's response can be set using the After Power Failure
feature in the BIOS Setup program's Boot menu.
