The NIC supports the Wired-for-Management (WfM) standard of Wake-On-LAN (WOL) that 
allows the system to be booted up from a powered-down or low-power condition upon the 
detection of special packets received over a network. The NIC receives 3.3 VDC auxiliary power 
while the system unit is powered down in order to process special packets. The detection of a 
Magic Packet by the NIC results in the PME- signal on the PCI bus to be asserted, initiating 
system wake-up from an ACPI S1 or S3 state. 

Alert Standard Format (ASF) support allows the NIC to communicate the occurrence of certain 
events over a network to an ASF 1.0-compliant management console and, if necessary, take 
action that may be required. The ASF communications can involve the following:

■

Alert messages sent by the client to the management console.

■

Maintenance requests sent by the management console to the client.

■

Description of client's ASF capabilities and characteristics.

The activation of ASF functionality requires minimal intervention of the user, typically requiring 
only booting a client system that is connected to a network with an ASF-compliant management 
console.  

The NIC features Wired-for-Management (WfM) support providing system wake up from 
network events (WOL) as well as generating system status messages (AOL) and supports ACPI 
power management environments.  The controller receives 3.3 VDC (auxiliary) power as long as 
the system is plugged into a live AC receptacle, allowing support of wake-up events occurring 
over a network while the system is powered down or in a low-power state.

The Advanced Configuration and Power Interface (ACPI) functionality of system wake up is 
implemented through an ACPI-compliant OS and is the default power management mode. The 
following wakeup events may be individually enabled/disabled through the supplied software 
driver: 

■

Magic Packet—Packet with node address repeated 16 times in data portion

✎

The following functions are supported in NDIS5 drivers but implemented through remote 
management software applications (such as LanDesk).

■

Individual address match—Packet with matching user-defined byte mask

■

Multicast address match—Packet with matching user-defined sample frame

■

ARP (address resolution protocol) packet

■

Flexible packet filtering—Packets that match defined CRC signature 

The PROSet Application software (pre-installed and accessed through the System Tray or 
Windows Control Panel) allows configuration of operational parameters such as WOL and 
duplex mode.
