Chapter 5 Input/Output Interfaces

As shown in the following figure, support with an AOL-compliant NIC PCI card (such as the Intel PRO/100+ Management Adapter Solution) requires no auxiliary cable since the communication of alert events is handled through the PCI bus interface.

Figure 5-12.AOL Implementation (Generic Representation)

The 82801 ICH initiates event notification by transmitting an alert message over the SMBus-type Alert Clock/Alert Data interface to a NIC card. On these systems the Alert Clock/Alert Data signals are wired-Or’d with the SMBus signals and use the SDONEn/SBOn signals lines for routing to a NIC card on the PCI bus.

The ICH’s alert message will be the result of a signal from a sensor (thermal or CPU state) or from the ICH’s detection of the system’s running status. Upon receiving the alert message from the ICH the NIC transmits the appropriate, pre-constructed message over the network.

The AOL implementation requirements are as follows:

1.Intel PRO/100 network drivers 4.11 or later (available from Compaq).

2.Intel Alert-On-LAN Utilities, version 2.6 (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)
