In addition, software, drivers, and peripherals must fully support ACPI wake events. 1.11.2 Hardware Support CAUTION Ensure that the power supply provides adequate +5 V standby current if LAN wake capabilities and Instantly Available PC technology features are used. 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. The board provides several power management hardware features, including: • Power connector • Fan headers • LAN wake capabilities • Instantly Available PC technology • Wake from USB • PCI Express WAKE# signal support • Wake from S5 • +5 V Standby Power Indicator LED LAN wake capabilities and Instantly Available PC technology require power from the +5 V standby line. NOTE The use of Wake from USB from an ACPI state requires an operating system that provides full ACPI support. 35

Hardware Support
CAUTION
Ensure that the power supply provides adequate +5 V standby current if LAN wake
capabilities and Instantly Available PC technology features are used.
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.
The board provides several power management hardware features, including:
•
Power connector
•
Fan headers
•
LAN wake capabilities
•
Instantly Available PC technology
•
Wake from USB
•
PCI Express WAKE# signal support
•
Wake from S5
•
+5 V Standby Power Indicator LED
LAN wake capabilities and Instantly Available PC technology require power from the
+5 V standby line.
NOTE
The use of Wake from USB from an ACPI state requires an operating system that
provides full ACPI support.
