Product Description 1.13.2.3 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* 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 bus PME# signal for PCI 2.2 compliant LAN designs • The onboard LAN subsystem 1.13.2.4 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 13 on page 34 lists the devices and events that can wake the computer from the S3 state. The board supports the PCI Bus Power Management Interface Specification. For information on the version of this specification, see Section 1.5. 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. 1.13.2.5 +5 V Standby Power Indicator LED The +5 V standby power indicator LED shows that power is still present even when the computer appears to be off. Figure 3 shows the location of the standby power indicator LED. CAUTION If AC power has been switched off and the standby power indicator is still lit, disconnect the power cord before installing or removing any devices connected to the board. Failure to do so could damage the board and any attached devices. 37

1.13.2.3
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* 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 bus PME# signal for PCI 2.2 compliant LAN designs
•
The onboard LAN subsystem
1.13.2.4
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 13 on
page 34 lists the devices and events that can wake the computer from the S3 state.
The board supports the
PCI Bus Power Management Interface Specification
.
For information on
the version of this specification, see Section 1.5.
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.
1.13.2.5
+5 V Standby Power Indicator LED
The +5 V standby power indicator LED shows that power is still present even when the computer
appears to be off.
Figure 3 shows the location of the standby power indicator LED.
CAUTION
If AC power has been switched off and the standby power indicator is still lit, disconnect the power
cord before installing or removing any devices connected to the board.
Failure to do so could
damage the board and any attached devices.
