32 Intel Server Board S845WD1-E Product Guide
Power Connector
When used with an ATX12V or EPS-12 V compliant power supply that supports remote power
on/off, the S845WD1-E server board can turn off the system power through software control.
When the system BIOS receives the correct command from the operating system, the BIOS turns
off power to the computer.
With soft-off enabled, if power to the computer is interrupted by a power outage or a disconnected
power cord, when power resumes, the computer returns to the power state it was in before power
was interrupted (on or off). The computer’s response can be set using the After Power Failure
feature in the BIOS Setup program’s Boot menu.
Fan Connectors
Table 8 summarizes the function/operation of the fan connectors.
Table 8. Fan Connector Function/Operation
Connector Description
Processor fan (CPU
FAN)
• +12 V DC connection for a processor fan or active fan heat sink.
• Fan is on in the S0 or S1 state.
Fan is off when the system is off or in the S3, S4, or S5 state.
• Wired to a fan tachometer input of the Hardware Management ASIC.
Front and rear chassis
fans (FAN1, FAN2,
and FAN3)
• +12 V DC connection for a system or chassis fan.
• Fan is on in the S0 or S1 state.
Fan is off when the system is off or in the S3, S4, or S5 state.
• Wired to a fan tachometer input of the Hardware Management ASIC.
LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the 5 V standby line for the power supply must
be capable of providing adequate +5 V standby current. Failure to provide
adequate standby current when implementing LAN wake capabilities can
damage the power supply.
LAN wake capabilities enable remote wake-up of the computer through a network. The LAN
subsystem PCI bus network adapter monitors network traffic at the Media Independent Interface.
Upon detecting a Magic Packet
†
frame, the LAN subsystem asserts a wake-up signal that powers up
the computer.
Depending on the LAN implementation, the S845WD1-E server board supports LAN wake
capabilities with ACPI in the following ways:
• The PCI bus PME# signal for PCI 2.2 compliant LAN designs
• The onboard LAN subsystem
