Power and Signal Distribution
The wake up sequence for each event occurs as follows:
Wake-On-LAN
The network interface controller (NIC) can be configured for detection of a “Magic Packet” and
wake the system up from sleep mode through the assertion of the PME- signal on the PCI bus.
Refer to Chapter 5, “Network Support” for more information.
Modem Ring
A ring condition on a serial port can be detected by the power control logic and, if so configured,
cause the PS On signal to be asserted.
Power Management Event
A power management event that asserts the PME- signal on the PCI bus can be enabled to cause
the power control logic to generate the PS On. Note that the PCI card must be PCI ver. 2.2 (or
later) compliant to support this function.
