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.
Ÿ
The total length of all Ethernet cables connecting the
systems in the ASM Interconnect network should not
exceed 300 feet.
Ÿ
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
