The following subsections describe the management interfaces and network
components shown in Figure 2-1
.
The NonStop TCP/IP product for NonStop servers provides transparent connections to
IEEE 802.3 Ethernet LANs and IEEE 802.5 token-ring LANs through the SLSA
subsystem. NonStop TCP/IP uses the WAN subsystem to interface to X.25 packet-
switched networks. For more information about the WAN subsystem, refer to the WAN
Subsystem Configuration and Management Manual. NonStop TCP/IP uses the ATM
subsystem to interface to ATM networks. For more information about the ATM
subsystem, refer to the ATM Configuration and Management Manual.
ATM3SA
A ServerNet adapter that provides access to Asynchronous Transfer Mode (ATM)
networks from a NonStop S-series server. The ATM3SA supports the ATM
User-Network Interface (UNI) specification over a 155-megabit per second (Mbps)
OC-3 Sonet (Synchronous Optical Network) connection.
DSM
An interface and set of tools used to configure, control, and manage NonStop servers
and Expand networks. DSM includes the SPI interface-to-management process, in
addition to other tools that assist in the development of applications.
E4SA
A ServerNet adapter for Ethernet local area networks (LANs) that contains four
Ethernet ports.
Fast Ethernet ServerNet Adapter (FESA)
A single-port ServerNet adapter that supports 100-Mbps and 10-Mbps Ethernet data-
transfer rates on a NonStop S-series server. The FESA installs into an Ethernet port.
One FESA is supported for each system enclosure.
G4SA
A multiport ServerNet adapter that provides 1000 megabits/second (Mbps) data
transfer rates between NonStop S-series servers, Integrity NonStop NS-series servers,
and Ethernet LANs. The G4SA is the only LAN adapter supported for the I/O Adapter
Module (IOAM) enclosure, and it is installed in slots 1, 2, 3, 4, and 5 of an IOAM.
Although the G4SA supersedes the Ethernet 4 ServerNet adapter (E4SA), Fast
Ethernet ServerNet adapter (FESA), and the Gigabit Ethernet ServerNet adapter
(GESA), it cannot be installed in an HP NonStop S-series I/O enclosure.
