Intel Desktop Board D845PEBT2 Technical Product Specification 1.16.2.3 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. Refer to Section 2.11.3 on page 80 for additional information. 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 Desktop Board D845PEBT2 supports LAN wake capabilities with ACPI in the following ways: • PCI bus PME# signal for PCI 2.2 compliant LAN designs • Onboard LAN subsystem 1.16.2.4 Instantly Available PC Technology CAUTION For Instantly Available PC technology, 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 Instantly Available PC technology can damage the power supply. Refer to Section 2.11.3 on page 80 for additional information. Instantly Available PC technology enables the Desktop Board D845PEBT2 to enter the ACPI S3 (Suspend-to-RAM) sleep-state. While in the S3 sleep-state, the computer will appear to be off (the power supply is off, and the front panel LED is amber if dual colored, or off if single colored.) When signaled by a wake-up device or event, the system quickly returns to its last known wake state. Table 8 on page 40 lists the devices and events that can wake the computer from the S3 state. The Desktop Board D845PEBT2 supports the PCI Bus Power Management Interface Specification. For information on the version of this specification, see Section 1.4. Add-in boards that also support this specification can participate in power management and can be used to wake the computer. The use of Instantly Available PC technology requires operating system support and PCI 2.2 compliant add-in cards and drivers. 42

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.
Refer to Section 2.11.3 on
page 80 for additional information.
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 Desktop Board D845PEBT2
supports LAN wake capabilities with ACPI in the following ways:
•
PCI bus PME# signal for PCI 2.2 compliant LAN designs
•
Onboard LAN subsystem
1.16.2.4
Instantly Available PC Technology
CAUTION
For Instantly Available PC technology, 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 Instantly Available PC technology can damage the power supply.
Refer to
Section 2.11.3 on page 80 for additional information.
Instantly Available PC technology enables the Desktop Board D845PEBT2 to enter the ACPI S3
(Suspend-to-RAM) sleep-state.
While in the S3 sleep-state, the computer will appear to be off (the
power supply is off, and the front panel LED is amber if dual colored, or off if single colored.)
When signaled by a wake-up device or event, the system quickly returns to its last known wake
state.
Table 8 on page 40 lists the devices and events that can wake the computer from the
S3 state.
The Desktop Board D845PEBT2 supports the
PCI Bus Power Management Interface
Specification
.
For information on the version of this specification, see Section 1.4.
Add-in boards
that also support this specification can participate in power management and can be used to wake
the computer.
The use of Instantly Available PC technology requires operating system support and PCI 2.2
compliant add-in cards and drivers.
