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 connectors
• LAN wake capabilities
• Instantly Available PC technology
• Resume on Ring
• Wake from USB
• Wake from PS/2 keyboard
• PME# signal wake-up support
LAN wake capabilities and Instantly Available PC technology require power from the
+5 V standby line. The sections discussing these features describe the incremental
standby power requirements for each.
