Product Description

1.12.2.3

LAN Wake Capabilities

CAUTION

For LAN wake capabilities, the +5 V standby line from 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 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

•

The onboard LAN subsystem

1.12.2.4

Instantly Available PC Technology

CAUTION

For Instantly Available PC technology, the +5 V standby line from 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 10 on page 43 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 and drivers.

1.12.2.5

Resume on Ring

The operation of Resume on Ring can be summarized as follows:

•

Resumes operation from ACPI S3 state

•

Detects incoming call similarly for external and internal modems

•

Requires modem interrupt be unmasked for correct operation
