Required Hardware and Software
Several hardware and software components are required in addition to the Expand-
over-IP line-handler process to provide Expand-over-IP connectivity.
Figure 8-1 shows the relationship between the Expand subsystem, the NonStop
TCP/IP subsystem and the LAN adapter. The TCP/IP process in this configuration can
be either a NonStop TCP/IP or NonStop TCP/IPv6 (TCP6SAM process). (However, in
the case of NonStop TCP/IPv6, the architecture is somewhat different in that the
TCP6SAM process is actually not providing the connectivity. For simplicity, it is shown
here as interchangeable with the NonStop TCP/IP process for Expand purposes. For
more information about the architectures of this subsystem, see the TCP/IPv6
Configuration and Management Manual.)
