Technical Reference Guide

I.2.1 AOL FUNCTION

The adapter’s Alert-On-LAN (AOL) function provides a AOL-compliant system unit with the ability to communicate system status to a management console, even while the system is powered down. When installed in an AOL-compliant system, the adapter receives alert messages from the system’s I/O Controller Hub (ICH) over the PCI bus. Each alert message decoded by the adapter results in a pre-constructed status message being transmitted over the network to a management console.

Alert-On-LAN functionality occurs independent of software, driver, or even processor intervention. The adapter can report following conditions:

♦System tampering – Removal of the chassis cover

♦BIOS failure – System fails to boot successfully

♦OS problem – System fails to load operating system after boot

♦Missing/faulty processor – Processor fails to fetch first instruction

♦Thermal condition – High temperature detected in system

♦Heartbeat – Indication of system’s presence on the network (sent approximately every 30 seconds)

NOTE: The system unit must be plugged into a live AC outlet for the AOL function to be

operative. Controlling a system unit’s power through an AC outlet strip will, when the strip is turned off, disable AOL functionality.

The AOL implementation requirements are as follows:

1.System unit featuring the 810, 810e, 820, or 850 (or later) chipset.

2.Intel PRO/100+ Management Adapter Driver 3.1 or later (available from Compaq).

3.Client-side utility agent software (available from Compaq).

4.Management console running one of the following:

a.HP OpenView Network Node Manager 6.x.

b.Intel LANDesk Client Manager.

c.Compaq Insight Manager.

I.2.2 WAKE UP FUNCTIONS

The adapter provides two types of wake-up signaling: the PME- signal and the WOL signal.

The adapter provides PME- signal support for systems compliant with PCI ver. 2.2. The detection of any wake event results in the adapter’s assertion of the PME- signal, which can be used by the system unit to initiate the power-up sequence. System software is responsible for the clearing the PME- signal.

The adapter also includes a WOL interface for systems supporting that method of wake-up. The adapter asserts the WOL signal for 50 milliseconds upon detection of a Magic Packet. The WOL signal is routed to the system unit (through a three-conductor cable connection) for initializing a power-up sequence.
