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* frame, the LAN subsystem
asserts a wake-up signal that powers up the computer. Depending on the LAN
implementation, the VIG390S motherboard supports 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


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 VIG390S motherboard 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
coloured, or off if single coloured.) When signalled by a wake-up device or event, the
system quickly returns to its last known wake state.

The use of Instantly Available PC technology requires operating system support and
PCI 2.2 compliant add-in cards and drivers.

Resume on Ring

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

• 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
