LAN Wake Capabilities, Instantly Available PC Technology, Upon detecting a Magic Packet

Page 31 highlights

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 S845WD1H server 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 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. The S845WD1H server board supports the PCI Bus Power Management Interface Specification. Add-in Board 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. The standby power indicator LED shows that power is still present even when the computer appears to be off. Figure 4 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. Description 31

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 S845WD1H server 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
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.
The S845WD1H server board supports the
PCI Bus Power Management Interface Specification
.
Add-in Board 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.
The standby power indicator LED shows that power is still present even when the computer
appears to be off.
Figure 4 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.
