WHITE PAPER (cont'd) Compaq Professional Workstation - Key Technologies Supported Alerts The Alert on LAN solution supports the alerts listed in Table 1. Table 1. Alerts supported by the Intel PRO/100+ Management Adapter Alert Description Benefits BIOS Hang The NIC issues a BIOS hang alert if the PC determines that the system BIOS has hung up during POST. Enables a proactive response to failed automated processes. OS Hang The NIC issues an OS hang alert if the PC determines that the OS has failed to load. Enables a proactive response to failed automated processes. Missing Processor The missing processor alert occurs if the chipset does not detect the processor during the initial boot. Enables a quick response to theft, intrusion, improper processor seating, or a defective processor; minimizes costly losses and downtime. Thermal The NIC issues a thermal alert if the PC's Thermal and Fan Control (TAFI) integrated circuit detects an over-temperature condition. Enables a proactive response to specific thermal problems; minimizes damage and downtime caused by overheating. Chassis Intrusion The NIC issues a chassis intrusion alert if someone removes the PC's cover (hood) and activates the hood sensor switch. Enables a quick response to theft or intrusion. NOTE: Even if disconnected from utility power, the PC can store a chassis intrusion event. When power is restored, the NIC issues the appropriate alert. Heartbeat This real-time monitor checks for the presence of the PC on the LAN and issues an alert if the PC is not present. Enables a quick response if the PC has been disconnected from the network for any reason. The high-level process for reporting a NIC alert (for example, a chassis intrusion alert) using the Intel PRO/100+ Management Adapter on a Compaq Professional Workstation is: 1. The PC's hood is removed. 2. This activates the hood sensor switch, which sends a Hood Sense signal to the PC's input/output controller hub (ICH). 3. The ICH passes information about this event to the NIC via the NIC's PCI connector. 4. The NIC decodes the information from the ICH, identifies the event, and transmits the appropriate alert packet over the network to the management console. 12
