The ASM Interconnect network must be set up as a bus, not as a ring. Make sure the servers are connected to the ASM Interconnect network in series, with a beginning point and an end point. The total length of all Ethernet cables connecting the systems in the ASM Interconnect network should not exceed 300 feet. Each Advanced System management PCI Adapter or Advanced System Management Processor that is connected to the ASM Interconnect network bus counts as 1 connection. For example, if you have installed an Advanced System Management PCI Adapter option in a system that has an Advanced System Management Processor, the Processor and the Adapter are connected to each other using an ASM Interconnect connection and each count as a connection on the ASM Interconnect network bus. Advanced System Management Interconnect alert forwarding: Advanced System Management PCI Adapters and Advanced System Management Processors that are connected to an ASM Interconnect network share resources and system management information. This section provides information on how alerts are shared and forwarded in the ASM Interconnect network. During normal operation, each Advanced System Management Processor or PCI Adapter on the ASM Interconnect network communicates with the other processors and adapters on the network. Processors or adapters that have a modem, Ethernet, or Token Ring connection "tell" the other processors and adapters that these communications resources are available for use by other systems on the ASM Interconnect network. These communications resources can now be used as ASM Interconnect network resources, enabling any Advanced System Management Processor or PCI Adapter on the ASM Interconnect network to send alerts to a modem or an IP address, even if they do not have a modem or network connection physically attached. As they generate alerts, the alerts are forwarded to the Advanced System Management Processor or PCI Adapter on the ASM Interconnect network that has the communications resources necessary to forward the alert. If no system on the ASM Interconnect network meets the requirements, the alert is not forwarded and is discarded. If multiple modems or multiple network connections exist in the ASM Interconnect network, you cannot specify which system will receive an alert or which will use its modem or network connection to forward the alert. If an alert is forwarded to another Advanced System Management Processor or PCI Adapter that is unable to deliver the alert 82 Netfinity Server HMM
