Wake on LAN Technology (Optional)
CAUTION
For Wake on LAN 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 Wake on LAN technology can damage the power supply.
The optional Wake on LAN technology connector can be used with PCI bus network adapters that
have a remote wake-up connector. Network adapters that are PCI 2.2 compliant assert the wake-up
signal using the PCI bus signal PME# (pin A19 on the PCI bus connectors). See Figure 30 on
page 82 for the location of the Wake on LAN technology connector on the desktop board.
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 Wake on LAN technology can damage the power supply.
CAUTION
If the standby current necessary to support multiple wake events from the PCI and/or USB buses
exceeds power supply capacity, the desktop board may lose register settings stored in memory.
Instantly Available 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. When signaled by a wake-up
device or event, the system quickly returns to its last known awake state.
The desktop board standby power indicator, shown in Figure 3, is lit when the memory modules
and PCI bus connectors have power, even when the computer appears to be off.
If the system has a dual-colored power LED on the front panel, the sleep state is indicated by the
LED turning amber. For more information about front panel LED states, see the Intel
