Input/Output Interfaces

✎For the features in the following paragraphs to function as described, the system unit must be plugged into a live AC outlet. Controlling unit power through a switchable power strip will, with the strip turned off, disable any wake, alert, or power management functionality.

5.8.1Wake-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 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.

5.8.2 Power Management Support

The NIC supports WOL and ACPI power management environments. The controller receives

3.3VDC (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:

■Wake on Pattern Match (Windows 7)

■Wake on Directed Packets (Windows XP and Windows Vista)

The PROSet Application software (pre-installed and accessed through the NIC Properties (inside Device Manager) allows configuration of operational parameters such as WOL and duplex mode.

5.8.3 NIC Connector

Figure 5-11 shows the RJ-45 connector used for the NIC interface. This connector includes the two status LEDs as part of the connector assembly.
