Replacing an ATM3SA CRU

Identifying the Communications Lines That
Use an ATM3SA CRU
The Asynchronous Transfer Mode (ATM) subsystem provides access to the ATM
ServerNet adapter (ATM3SA) CRU. The following NonStop subsystems and utilities
may be configured to access an ATM3SA CRU through the ATM subsystem:
The TCP/IP subsystem, which can interface to the ATM subsystem to provide
connectivity to TCP/IP networks. The following NonStop subsystems and utilities
can interface to the TCP/IP subsystem to use an ATM3SA CRU:
The Expand subsystem, which can be configured to establish
Expand-over-IP connections through the TCP/IP subsystem.
●
Telserv and the File Transfer Protocol (FTP), which use the socket library
to establish connections through the TCP/IP subsystem.
❍
Other NonStop subsystems that can be configured to establish connections
through the TCP/IP subsystem.
❍
●
The Expand subsystem, which can interface to the ATM subsystem to provide
Expand-over-ATM connections.
●
The figure illustrates how these subsystems and utilities use the ATM subsystem to
access an ATM3SA CRU.
The following procedure should help you identify the NonStop subsystems and utilities
that are configured to use an ATM3SA CRU. Specific instructions are provided for
identifying Expand-over-IP and Expand-over-ATM lines.
Tip: You will need to make a note of the information you obtain during this
procedure. You can record this information on the planning worksheet provided or you
can use the SCF LOG command to capture both the command and the display that is
produced to a file. To start logging, type LOG <logfilename> at the SCF prompt. To
stop logging, type LOG at the SCF prompt.
