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
subsystem PCI bus network adapter monitors network traffic at the Media Independent Interface.
Upon detecting a Magic Packet
up the computer. Depending on the LAN implementation, the Desktop Boards support 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
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 Desktop Boards 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 12 on page 33 lists the devices and events that can wake the computer from the
S3 state.
The Desktop Boards support 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.
