Intel Desktop Board D850MD/D850MV Technical Product Specification
1.14.2.3 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. Refer to Section 2.11.3 on
page 80 for additional information.
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 MII. 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 D850MD and D850MV boards support LAN wake
capabilities in the following ways, which are with ACPI only:
Through the PCI bus PME# signal for PCI 2.2–compliant LAN designs
Through the onboard LAN subsystem
Through a CNR-based LAN subsystem
1.14.2.4 Instantly Available Technology
CAUTION
For Instantly Available 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 technology can damage the power supply. Refer to
Section 2.11.3 on page 80 for additional information.
Instantly Available technology enables the D850MD and D850MV boards 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 fan 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 11 on page 41 lists the devices and events that can wake the computer from the S3
state.
The D850MD and D850MV boards support the PCI Bus Power Management Interface
Specification. For information on the versions 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 technology requires operating system support and
PCI 2.2–compliant add-in cards and drivers.
