Wake On Lan Support; Alert On Lan Support - HP Compaq D315 Technical Reference Manual

NOTE: For the WOL and AOL features to function as described in the following
paragraphs, 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 WOL and
AOL functionality.

5.9.1 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.

5.9.2 ALERT ON LAN SUPPORT

Alert-On-LAN (AOL) support allows the NIC to communicate the occurrence of certain events
over a network even while the system unit is powered off. In a system-off (powered down)
condition the network function of the 82801 ICH component receives auxiliary +3.3 VDC power
(derived from the +5 VDC auxiliary power from the power supply assembly). Certain events
(listed in Table 5-24) will result in the network function of the ICH to transmit an appropriate pre-
constructed message over the network to a system management console.
Reportable AOL events are listed in the following table:

The AOL implementation requirements are as follows:
1. Intel PRO/100 VM Network Connection drivers 3.80 or later (available from Compaq).
2. Intel Alert-On-LAN Utilities, version 2.5 (available from Compaq).
3. Management console running one of the following:
a. HP OpenView Network Node Manager 6.x
b. Intel LANDesk Client Manager
c. Sample Application Console from the Intel AOL Utilities (item #2 above)
Table 5-24.
