Hardware Support - Intel BOXD2700DC Specification

Intel Desktop Board D2700DC Technical Product Specification
1.11.2

Hardware Support

The board provides several power management hardware features, including:
• Power connector
• Fan header
• LAN wake capabilities
• Instantly Available PC technology
• Wake from USB
• Power Management Event signal (PME#) wake-up support
• WAKE# signal wake-up support
• +5V 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 technologies from an ACPI state requires an operating
system that provides full ACPI support.
1.11.2.1 Fan Header
The function/operation of the fan header is as follows:
• The fan is on when the board is in the S0 state.
• The fan is off when the board is off or in the S3, S4, or S5 state.
• The system fan header supports closed-loop fan control that can adjust the
fan speed and is wired to a fan tachometer input.
• The fan header supports +12 V, 3-wire fans at 1 A maximum.

1.11.2.2 LAN Wake Capabilities
LAN wake capabilities enable remote wake-up of the computer through a network.
The LAN subsystem network adapter monitors network traffic at the Media
Independent Interface. The board supports LAN wake capabilities with ACPI in the
following ways:
• By Ping
• By Magic Packet
Upon detecting the configured wake packet type, the LAN subsystem asserts a wake-
up signal that powers up the computer.
