Desktop Board Features LAN Wake Capabilities CAUTION For LAN wake capabilities, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature 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 board supports LAN wake capabilities with ACPI in the following ways: • The PCI Express WAKE# signal • The PCI bus PME# signal for PCI 2.3 compliant LAN designs • By Ping • Magic Packet • The onboard LAN subsystem Desktop Board DQ35JO supports waking the Intel Management Engine over the network. This can be enabled in the BIOS and allows Intel AMT to be remotely turned on through a wake packet generated by a management console application or a ping. The client system will be in a low power state until a management console alert requests Intel AMT functionality. Instantly Available PC Technology CAUTIONS For Instantly Available PC technology, the 5 V standby line for the power supply must be capable of delivering adequate +5 V standby current. Failure to provide adequate standby current when using this feature can damage the power supply and/or effect ACPI S3 sleep state functionality. Power supplies used with this Desktop Board must be able to provide enough standby current to support the standard Instantly Available (ACPI S3 sleep state) configuration. If the standby current necessary to support multiple wake events from the PCI and/or USB buses exceeds power supply capacity, the Desktop Board may lose register settings stored in memory. Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-toRAM) sleep state. While in the S3 sleep state, the computer will appear to be off. If the computer has a dual-colored power LED on the front panel, the sleep state is indicated by the LED turning amber. When signaled by a wake-up device or event, the computer quickly returns to its last known awake state. 27

LAN Wake Capabilities
CAUTION
For LAN wake capabilities, the 5 V standby line for the power supply must be capable
of delivering adequate +5 V standby current.
Failure to provide adequate standby
current when using this feature 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 board supports LAN wake capabilities with ACPI in the following
ways:
•
The PCI Express WAKE# signal
•
The PCI bus PME# signal for PCI 2.3 compliant LAN designs
•
By Ping
•
Magic Packet
•
The onboard LAN subsystem
Desktop Board DQ35JO supports waking the Intel Management Engine over the
network.
This can be enabled in the BIOS and allows Intel AMT to be remotely turned
on through a wake packet generated by a management console application or a ping.
The client system will be in a low power state until a management console alert
requests Intel AMT functionality.
Instantly Available PC Technology
CAUTIONS
For Instantly Available PC technology, the 5 V standby line for the power supply must
be capable of delivering adequate +5 V standby current.
Failure to provide adequate
standby current when using this feature can damage the power supply and/or effect
ACPI S3 sleep state functionality.
Power supplies used with this Desktop Board must be able to provide enough standby
current to support the standard Instantly Available (ACPI S3 sleep state) configuration.
If the standby current necessary to support multiple wake events from the PCI and/or
USB buses exceeds power supply capacity, the Desktop Board may lose register
settings stored in memory.
Instantly Available PC technology enables the board to enter the ACPI S3 (Suspend-to-
RAM) sleep state.
While in the S3 sleep state, the computer will appear to be off.
If
the computer has a dual-colored power LED on the front panel, the sleep state is
indicated by the LED turning amber.
When signaled by a wake-up device or event, the
computer quickly returns to its last known awake state.
