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.
