1.12.2.3 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.
LAN wake capabilities enable remote wake-up of the computer through a network. The LAN
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 Conventional bus PME# signal for PCI 2.3 compliant LAN designs
•
The onboard LAN subsystem
1.12.2.4 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.
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 (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 9 on
page 41 lists the devices and events that can wake the computer from the S3 state.
The board supports the PCI Bus Power Management Interface Specification. 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 2.3
compliant add-in cards, PCI Express add-in cards, and drivers.
