Input/Output Interfaces
5.10.1 Wake-On-LAN Support
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.
5.10.2 Alert Standard Format Support
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.
5.10.3 Power Management Support
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.
