Chapter 5  Input/Output Interfaces 

 
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 both 
APM and 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 occuring over a network while the system is powered down or in a low-power state. 

 

 

 
The Advanced Power Management (APM) functionality of system wake up is implemented 
through the system’s APM-compliant BIOS and the controller’s Magic Packet-compliant 
hardware.  This environment bypasses operating system (OS) intervention allowing a plugged in 
unit to be turned on remotely over the network (i.e., “remote wake up”). In APM mode the 
controller will respond upon receiving a Magic Packet, which is a packet where the node’s 
address is repeated 16 times. Upon Magic packet detection, the controller initiates the boot 
sequence.  

 

 
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 

 

NOTE: 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.
