Replacing an E4SA CRU

Identifying the Communications Lines and
SWAN Concentrators That Use an E4SA CRU
The ServerNet LAN Access Method (SLSA) subsystem provides access to the
Ethernet 4 ServerNet adapter (E4SA) CRU. The following NonStop subsystems and
utilities may be configured to access an E4SA CRU through the SLSA subsystem:
The TCP/IP subsystem, which can interface to the SLSA subsystem to provide
connectivity to TCP/IP networks. The following NonStop subsystems and utilities
can interface to the TCP/IP subsystem to use an E4SA CRU:
The WAN subsystem, which interfaces to the TCP/IP subsystem to provide
access to ServerNet wide area network (SWAN) concentrators, and the
WAN subsystem input/output processes (IOPs) that use the SWAN
concentrators.
●
The Expand subsystem, which interfaces to the TCP/IP subsystem to
provide Expand-over-IP connections.
❍
Telserv and the File Transfer Protocol (FTP), which use the socket library
to establish remote connections and communicate through the TCP/IP
subsystem.
❍
Other NonStop subsystems, such as Remote Server Call (RSC), that can
be configured to establish connections through the TCP/IP subsystem.
❍
●
The Port Access Method (PAM) subsystem, which can interface to the SLSA
subsystem to provide an independent interface to Ethernet networks, and the
user applications written using the PAM subsystem port interface.
●
The IPX/SPX subsystem, which can interface to the SLSA subsystem to provide
access to Novell NetWare networks. The following NonStop utilities and
subsystems can interface to the IPX/SPX subsystem to use an E4SA CRU:
Telserv and FTP, which use the socket library to establish remote
connections and communicate through the IPX/SPX subsystem.
●
NonStop subsystems, such as Remote Server Call (RSC), that can be
configured to establish connections through the IPX/SPX subsystem.
❍
●
The SNAX/XF and SNAX/APN subsystems, which can interface to the SLSA
subsystem to provide SNAX/Ethernet connectivity.
●
The figure illustrates how some of these subsystems and utilities use the SLSA
subsystem to access an E4SA CRU.
The following procedure should help you identify the NonStop subsystems and utilities
that are configured to use an E4SA CRU. Specific instructions are provided for
