Compaq W4000 manual Wake on LAN Support, Alert on LAN Support, AOL Events, Event Description

Technical Reference Guide

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 ICH2 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 ICH2 to transmit an appropriate pre-constructed message over the network to a system management console.

Reportable AOL events are listed in the following table:

Table 5–24. AOL Events

	Table 5-24.
	AOL Events
Event	Description
BIOS Failure	System fails to boot successfully.
OS Problem	System fails to load operating system after POST.
Missing/Faulty Processor	Processor fails to fetch first instruction.
Thermal Condition	Thermal ASIC reports high temperature.
Heartbeat	Indication of system’s network presence (sent approximately every 30
	seconds in normal operation).

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)
