Hardware Support

The S845WD1-E server 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# 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.
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).
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.
✏
NOTE
The use of Resume on Ring and Wake from USB technologies from an ACPI
state requires an operating system that provides full ACPI support.
