Wake-up Devices and Events

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.

Table 9 provides an overview of the devices or events that can wake the computer from specific states.

Table 9. Wake-up Devices and Events

These devices/events can wake up the computer…	…from this state

Power button	S1, S3, S4 (Note 1), S5
RTC alarm	S1, S3, S4 (Note 1), S5
LAN	S1, S3, S4 (Note 1), S5
PCI via PME# signal	S1, S3, S4 (Note 1), S5
Resume on Ring (back panel Serial Port A)	S1, S3

USB	S1, S3

PS/2	S1, S3

Notes:

1.For LAN and PME#, S5 is disabled by default in the BIOS Setup program. Setting this option to Power On will enable a wake-up event from LAN in the S5 state.

✏NOTE

The use of these wake-up events from an ACPI state requires an operating system that provides full ACPI support. In addition, software, drivers, and peripherals must fully support ACPI wake events.

LAN Wake

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 wakes up the computer from ACPI S1, S3, S4, and S5 state.

Depending on the LAN implementation, the S875WP1-E 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

PCI via PME# Wake-up Support

When the PME# signal on the PCI bus is asserted, the computer wakes from an ACPI S1, S3, S4, or S5 state (with Wake on PME enabled in BIOS).
