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:
•
•
•
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
40 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.
The operation of Resume on Ring can be summarized as follows:
•
•
•
USB bus activity wakes the computer from ACPI S1 or S3 states.
Wake from USB requires the use of a USB peripheral that supports Wake from USB.
PS/2 device activity wakes the computer from an ACPI S1 or S3 state.
When the PME# signal on the PCI Conventional bus is asserted, the computer wakes from an ACPI
S1, S3, S4, or S5 state (with Wake on PME enabled in BIOS).
NOTE
The PCI Express WAKE# signal
The PCI Conventional bus PME# signal for PCI 2.3 compliant LAN designs
The onboard LAN subsystem
Resumes operation from ACPI S1 or S3 states
Detects incoming call similarly for external and internal modems
Requires modem interrupt be unmasked for correct operation
